What to Do with Your Business Mail When You Close Your Physical Office
Closing your Montreal office? Here is exactly how to handle business mail — Canada Post, CRA, Revenu Quebec, and corporate records — so nothing slips through the cracks.
The day you hand back the keys is not the day your mail stops arriving at the old address. For most small businesses and teams in Montreal, the office closure itself takes an afternoon. The mail problem takes months, and for some businesses it creates real legal and financial consequences that show up long after the moving boxes are gone.
This guide is for businesses that are closing a physical office while continuing to operate. If you are winding down the company entirely, you will need additional steps around dissolution and final filings. What follows covers the more common situation: the lease ends, the team goes remote or moves to a lighter space, and the business keeps running. At that point, you have a mail problem that Canada Post forwarding alone will not solve.
Whether you are a solo founder closing your home-base office, a small team going fully remote, or a growing team moving into coworking or a smaller space in Griffintown, this guide walks through every category of mail and every registry that needs updating, in the order that matters.
The Moment the Lease Ends, Your Mail Problem Begins
Most businesses treat mail as a low priority during an office closure. There is space to clean out, equipment to move, people to settle, and a dozen other urgent tasks. Mail gets scheduled for "later this week" and then stays there. This is how small-business mail problems start.
What "closing the office" actually means for mail
When your lease ends and you vacate, your business mail does not automatically redirect. Any piece sent to your old address will arrive at that building, be received by whoever takes over the space, and either be held, forwarded, or discarded depending on the new tenant's goodwill. You have no control over any of it unless you take explicit action before you leave.
The other thing most businesses underestimate: Canada Post business mail forwarding lasts a maximum of 12 months and does not cover all mail types. It is a useful buffer, not a permanent solution. Every business closing an office needs a plan that extends past the forwarding window, and the time to build that plan is before you hand back the keys.
The scope of this guide is "business continues, physical office closes." Not dissolution. The mail problem is different when the company itself keeps operating, because the registries, compliance obligations, and banking relationships stay live and keep generating correspondence that needs to reach you.
The four categories of mail that cause real damage when they go missing
Not all business mail carries the same risk. Some of it is annoying to miss. Some of it is genuinely costly. The four categories that can cause real harm if they go to an old address are:
Tax and government correspondence. CRA assessment notices, audit letters, GST/HST correspondence, and payroll remittance confirmations are all sent to the address on file. Missing one of these does not pause the clock. Interest and penalties accumulate from the date the notice was sent, not from the date you eventually discover it existed.
Legal documents. Under the Canada Business Corporations Act (CBCA), a summons or other legal process served at your registered office address is deemed delivered, whether or not anyone receives it. If a supplier files a claim and the process server shows up at your old address after you have moved, the service is legally valid. You may not know about the proceeding until a default judgment exists against you.[4]
Banking and financial mail. Business card renewals, cheque books, and loan correspondence are mailed to the address on file with each institution. A replacement card mailed to a vacated office is not the bank's problem. Nor is a returned cheque from a client who mailed payment to the old address.
Client and vendor mail. Signed contracts, invoices, and purchase orders are still sent by paper mail in many industries. A missed signed contract or a cheque that goes to the wrong address creates cash flow and relationship problems that have nothing to do with the law and everything to do with operations.
Why the "I'll just forward everything" plan falls apart
Canada Post business mail forwarding sounds like the complete solution. It is not, and the limitations matter enough to address directly before anything else.
Canada Post's forwarding service covers Lettermail (standard envelopes) and Registered Mail within Canada. It does not cover parcels of any type, including Priority, Xpresspost, Expedited Parcel, and Regular Parcel. It does not cover prepaid reply envelopes, newspapers, advertising mail, or flyers.[1] Any piece marked "Do not forward" by the sender also stays at the old address.
There is another limitation that specifically affects businesses that were in coworking spaces, executive suites, or any building where multiple businesses shared a postal address. If more than two businesses share an address, Canada Post will not forward mail from that address at all. This catches many tenants by surprise.[1] If your Montreal business address was in a multi-tenant building with a shared postal code and more than two registered occupants, you may not be eligible for forwarding at all.
The plan this guide recommends is not "skip forwarding." It is to use forwarding as a short-term buffer while you work through the registry updates below, and then transition to a permanent solution before the 12-month window closes.

Before You Hand Back the Keys: A 48-Hour Checklist
The window between "I know I'm closing this office" and "the keys are back with the landlord" is the most valuable time you have. Once you have vacated, your leverage over the situation drops significantly.
The pre-departure mail audit
Before your last day in the space, go through the mailbox and sort everything into four categories: keep and act on, forward to the new address, return to sender, and shred. Do not leave anything in the mailbox for the next tenant to deal with.
Separately, take a few minutes to document every government registry where your business address appears. The list is longer than most small businesses expect. It includes CRA My Business Account (one entry per BN program account), Revenu Quebec, the Registraire des entreprises du Quebec (NEQ), and for incorporated businesses, Corporations Canada. These are four independent systems. None of them talk to each other. Updating one does not update the others.
Screenshot each account's registered address before you leave the space. This gives you a baseline to work from and evidence of what was on file at the time of the move, which can matter if a dispute arises later about whether a notice was sent to a valid address.
If your business address appears on your registered business address in any of these registries, the address shown is where government agencies and courts will send notices, and where process servers will attempt service. Getting this list right before you move is more valuable than any amount of forwarding.
Notify Canada Post before day one, not after
The forwarding order needs to be placed before or on the day you vacate. Canada Post does not apply forwarding retroactively to mail already delivered to the old address during the gap between your move-out date and the date the forwarding order activates.
You can place a Business Mail Forwarding order through Canada Post's online portal or at any post office. Forwarding periods are available in three-month, six-month, and twelve-month blocks. The maximum is twelve months with no renewal option. Choose the longest period you can, because the forwarding window is the time you have to complete all the registry updates below.
The cost is modest. The cost of not having it during a registry update period that takes two to three months is much higher. See the full breakdown of what forwarding covers in the next section.
For businesses that used a Montreal mailbox or virtual address at their office location, confirm with the building or mailbox provider what happens to mail addressed to your suite after your lease ends. Many commercial buildings will not hold mail for departed tenants beyond a short grace period.
Update your team's contact information immediately
On the day you move out, or ideally the day before, update every public-facing contact record that shows your old address. This includes every team member's email signature, voicemail greeting, LinkedIn profile, website contact page, and Google Business Profile.
The Google Business Profile update matters more than most businesses realize. Google's local search results and AI Overviews pull the address from your GBP listing. An outdated address in your GBP means that prospective clients who search for your business get directed to a space you no longer occupy. This creates a first impression problem that has nothing to do with your actual office situation and everything to do with how your business appears in search before anyone picks up the phone.
Update the GBP address to your new registered business address. If you do not have a new address yet, that is a reason to expedite the process described in the sections below, because operating with no current address on GBP also creates visibility problems. A coworking space address in Griffintown or a virtual mailbox address is a valid GBP address and gives you a professional Montreal location to display while you work through the transition.
Canada Post Business Mail Forwarding: The Full Picture
What Canada Post will forward from a business address
Canada Post's forwarding service is useful and worth using, but it covers a narrower range of mail than most businesses assume. Here is what the service actually includes and excludes, drawn directly from Canada Post's own guidance.[1]
Forwarded: Lettermail (standard letter-sized envelopes), Registered Mail within Canada, and magazines or periodicals with valid subscriptions.
Not forwarded: all parcel services without exception (Priority, Xpresspost, Xpresspost Certified, Expedited Parcel, Regular Parcel), prepaid reply envelopes, newspapers, advertising mail and flyers, personal mail at a business address, mail at any address shared by more than two businesses, mail handled through a privately-administered mailbox company (such as The UPS Store or Pakmail), and any piece the sender has marked "Do not forward."
This list matters because it means that any physical product sample, large-format document, or parcel your business receives will not be forwarded, regardless of the forwarding order. For businesses that regularly receive couriered contracts, product samples, or equipment, this gap requires a separate plan.
The shared-address trap that catches coworking tenants
The two-business limit on shared addresses is the most common forwarding limitation that catches Montreal businesses by surprise. If your old office was in a building where more than two businesses shared a single postal address, Canada Post will not forward mail from that address at all. The forwarding service simply cannot operate at an address with more than two occupants.
Many businesses that used a coworking space, executive suite, or multi-tenant commercial building as their registered address are in this situation. If this is your case, you will need to rely entirely on updating your registries directly rather than on forwarding as a buffer. This is also the situation where a virtual mailbox for your Montreal business becomes immediately relevant: a virtual mailbox provides a dedicated mailing address that belongs to you alone, with no sharing restrictions.
The 12-month ceiling and what happens when it expires
The maximum Canada Post business mail forwarding period is 12 months. There is no option to renew or extend beyond that. When the forwarding period expires, mail addressed to your old address is either returned to the sender or discarded by the postal carrier. There is no safety net and no notification that the window has closed.
This means you have at most 12 months from the day you leave to update every registry that matters. Set a calendar trigger at the 10-month mark to do a final sweep of all registries and confirm that no correspondence is still being forwarded. By month 12, the permanent solution needs to be in place, whether that is a new physical office address or a virtual mailbox in Montreal.

The CRA Address Update: What to Do and in What Order
Why CRA address updates are not one action
This is the most common misconception about CRA compliance during an office closure. Updating your address with CRA is not a single action. The Canada Revenue Agency maintains separate address records for each Business Number program account, and each one must be updated independently.[2]
A typical small incorporated business in Quebec might have three separate BN program accounts: GST/HST, payroll, and corporate income tax. Each of those has its own registered address on file. Updating the GST/HST address does not update the payroll address. Updating the corporate income tax address does not update either of the others.
For solo proprietors or freelancers with only a GST/HST account, the update is simpler: one program account, one update. For teams with payroll and corporate accounts as well, the update is three separate actions, and all three need to happen.
CRA's guidance says to notify them "as soon as possible" when an address changes.[2] There is no stated grace period, which means the risk window for a missed notice starts immediately when you vacate the old address.
How to update your CRA address: three paths
Online via My Business Account (fastest and recommended). Log in to CRA My Business Account, go to Profile, then Manage Addresses. Changes take effect immediately. If you do not already have a My Business Account registered, this is the moment to set one up: the online mail transition described in the next section makes My Business Account essential for every business operating in Canada as of mid-2025.
By phone. Call 1-800-959-5525, Monday to Friday, 8 a.m. to 8 p.m. Eastern time. This works well for sole proprietors who prefer to confirm changes verbally, but wait times vary.
By mail. The slowest path, with a processing lag of four to six weeks. Not recommended for an address change where you need the update reflected quickly. If you use this path, keep a copy of your mailed request and the date it was sent, because the effective date of the change will be the date CRA processes it, not the date you mailed it.
After updating each BN program account address in My Business Account, take a screenshot or print a confirmation. If CRA later sends a notice to an address you updated, a timestamped record of your update request is your evidence.
What CRA accepts as a new business address
This detail resolves a question many businesses ask when they are weighing their post-closure address options. CRA does not accept a Post Office Box or a rural route number as the registered business mailing address for most BN program account types.[2] A Canada Post PO Box is not a valid CRA business address.
A virtual mailbox address is different from a PO Box because it provides a real street address, not a numbered box. A virtual mailbox service operating from a Griffintown address, for example, gives your business a real Montreal street address that satisfies CRA's requirements. This is one of the key practical differences between a PO Box and a virtual office address in Montreal, and it is the reason that "just get a PO Box" does not work as a post-closure address solution for most businesses.
The CRA Online Mail Transition: The Change Most Businesses Miss
This section covers the single most significant and least-known compliance change affecting Canadian businesses in 2025. If you take nothing else from this guide, take this.
What changed in May and June 2025
Effective May 12, 2025 for new business registrations and June 16, 2025 for existing businesses with a My Business Account, the Canada Revenue Agency changed its default delivery method for business correspondence. CRA now sends correspondence online through My Business Account by default, rather than by paper mail.[3]
The critical phrase in CRA's announcement: correspondence is "considered received on the date posted to My Business Account."[3] Not on the date you read it. Not on the date you log in. On the date CRA posts it to your portal.
This changes the risk calculus for a business closing its office. The bigger risk is no longer a piece of paper going to an old address. The bigger risk is a business with a stale or inactive My Business Account email address that never receives the notification that a new document has been posted. CRA considers that document delivered on the day they posted it. Response deadlines run from that date.
What this means for businesses closing their office right now
A business closing its physical office in 2025 or 2026 needs to complete two steps at CRA, not one.
First, update the physical address in My Business Account for each BN program account, as described in the previous section.
Second, confirm that the email address registered in My Business Account is current and actively monitored. This is the email address CRA uses to notify you that new correspondence has been posted to your portal. If this email address was tied to an old office email domain, or to an account that a departing team member managed, it needs to be updated to an address someone checks regularly.
Missing either of these creates a gap. A correct physical address with a stale notification email means CRA can post documents to your portal without anyone knowing. A current notification email pointed at a My Business Account with a stale physical address means the next piece of paper CRA sends will still go to the wrong place.
For businesses that want to keep receiving paper mail from CRA rather than using the online portal, the opt-in process requires filing Form RC681 or selecting the paper mail option within My Business Account. Note that this opt-in must be renewed every two years.[3] For most businesses going through an office closure, defaulting to online delivery via My Business Account is actually the safer option: it removes dependence on a physical mailing address entirely, provided the notification email is current.
Building a durable address into this system
A virtual mailbox in Griffintown provides a stable physical address that satisfies CRA's street address requirement and does not change when your team's working arrangements change. This makes it a natural fit for the CRA physical address field: the address is consistent regardless of whether your team is remote, hybrid, or in a new coworking space. The My Business Account email address handles the actual notification; the street address is the compliance field that confirms you have a real business location.

Federal Corporate Registration: The 15-Day Clock
This section applies to federally incorporated businesses. If your business is not incorporated under the Canada Business Corporations Act, you can skip to the Revenu Quebec section. If you are not sure, check your incorporation documents or your entry in the Corporations Canada registry.
CBCA registered office requirements and the 15-day deadline
Under the Canada Business Corporations Act, section 19(4), federally incorporated businesses are required to file a change of registered office with Corporations Canada within 15 days of the change.[4] This is not a suggestion. It is a legal requirement with a specific deadline that most small incorporated businesses do not know about until after they have missed it.
The filing is Form 3 (Notice of Change of Registered Office Address). It is free to file, completed online through the Corporations Canada portal, and takes approximately one business day to process. The new registered office address cannot be a PO Box: a real street address is required.[4]
Why does the registered office address matter so much? Because it is the legally designated location where legal documents, including court summons and regulatory notices, can be served on your corporation. A process server who leaves documents at your registered office address has legally served your company, even if no one receives the documents, and even if the space is no longer occupied by your business. Updating this address within the 15-day window is the protection against that risk.
The 15-day clock starts on the day the actual move occurs, not on the day the lease ends or the day you planned to move.
Same-province versus cross-province moves
For the majority of Montreal businesses closing an office and staying in Quebec, the filing is straightforward: a directors-only resolution authorizing the address change, followed by Form 3. No shareholder vote is required when the registered office stays within the same province.
A move to a different province is more involved. It requires a special resolution approved by at least two-thirds of shareholders, and the filing is Form 4 rather than Form 3. Form 4 carries a $200 filing fee.[4] For a Montreal business staying in Quebec, this scenario does not apply.
Corporations Canada does not notify CRA
This is the gap that causes the most downstream problems. Updating your registered office with Corporations Canada does not notify the Canada Revenue Agency. These are two completely independent government systems. Updating one does not trigger any change to the other.
The full update for a federally incorporated Quebec business is: Corporations Canada (Form 3, 15-day deadline), CRA My Business Account (each BN program account separately, plus notification email), and Revenu Quebec (separate again, covered in the next section). Three systems, three independent updates, none of which will carry over to the others automatically.
Revenu Quebec: The Step Montreal Businesses Most Often Skip
Why updating CRA is not enough in Quebec
The most common misconception among Quebec business owners is that updating their address with CRA handles their provincial obligations as well. It does not.
The Canada Revenue Agency administers federal taxes (GST/HST, federal corporate income tax, federal payroll source deductions). Revenu Quebec administers Quebec provincial taxes (QST, Quebec income tax, Quebec payroll source deductions). These are separate governments with separate systems. An address update with CRA touches nothing in the Revenu Quebec system.[7]
Any business with Quebec tax obligations, which is nearly every business operating in Montreal, needs to update Revenu Quebec separately.
How to update Revenu Quebec
The fastest path is online through Revenu Quebec's business portal (clic Sequr). Log in, navigate to your business file, and update the registered address and mailing address. If the mailing address differs from the registered address, both need to be updated independently.
By phone: 1-800-567-4692, Monday to Friday during regular business hours.
Update the registered address, the mailing address if different, and the business contact information including the email address on file for Revenu Quebec correspondence. Revenu Quebec has also been expanding its online correspondence capabilities, so keeping the contact email current matters here as well.
NEQ update: the Quebec Enterprise Register
Every business registered with the Registraire des entreprises du Quebec (REQ) is required to update their business address in the Quebec Enterprise Register within 30 days of the change.[8] The NEQ registry is the publicly accessible record that clients, suppliers, financial institutions, and courts use to verify your business's existence and contact information.
Update your NEQ entry through the registreentreprises.gouv.qc.ca portal. The process is online and authenticated through clicSEQUR.
The 30-day deadline for the NEQ update is separate from the 15-day CBCA deadline for federally incorporated businesses. A business that is both federally incorporated and Quebec-registered has two deadlines: 15 days for Corporations Canada, 30 days for the REQ.

Banking, Insurance, and Vendor Notifications
Financial institutions
Each bank or credit union where your business holds accounts maintains its own address record. Updating CRA does not notify your bank. Updating your bank does not notify CRA. These are independent updates.
For each business bank account: update the registered address through the bank's online portal or by calling the commercial banking line directly. Many business banking portals default to a personal address field rather than a business address field during address updates; confirm that you are updating the business account address, not the individual account holder address.
Business credit card issuers, equipment lenders, and any financing arrangements your business has all maintain separate address records as well. A renewal card mailed to a closed office is a practical problem. A loan default notice mailed to a closed office is a more serious one.
Insurance and professional associations
Your business liability insurance policy lists a registered address, and that address is relevant to claims processing and policy renewal. Contact your broker or insurer directly to update the registered address on the policy. Do not assume the insurer will pick up a GBP or NEQ address change on their own.
Montreal businesses with members in professional orders (CPA Quebec, Barreau du Quebec, Ordre des architectes du Quebec, and others) need to update their membership address separately. Professional orders typically send renewal notices, continuing education requirements, and regulatory correspondence by paper mail. A lapsed address at the order means a lapsed membership without warning, which creates its own professional practice complications.
Key vendors and clients
If any clients pay by paper cheque, notify them of the new mailing address immediately. A cheque mailed to a closed office is not a payment that has arrived. Until it is in your account, it has not arrived.
For vendors that send invoices by mail, update your contact record with each of them. For subscription services that mail physical items (industry publications, document courier services, anything that ships regularly), update each separately.
If your business has any outstanding Canada Post couriered return addresses or any prepaid reply envelopes in circulation, those also need to be updated or voided.
For Solo Founders and Freelancers: Your Simplest Path Forward
If you are a solo founder or freelancer closing your office, the mechanics are simpler than for a multi-person team. That simplicity can be a liability as much as an advantage, because there is no team member to catch what you miss.
Why the solo closure is the least complex but has its own risks
A sole proprietor or single-person incorporated business typically has one GST/HST BN account, possibly one payroll account if they pay themselves through payroll, and no corporate income tax account if they operate as a sole proprietor rather than a corporation. Fewer registry entries means fewer updates.
The risk for the solo founder is not complexity. It is the fact that there is no one else checking. A two-person team has at least a second person who might notice that mail has stopped arriving. A solo founder going remote often treats mail as a background task during the transition and discovers six months later that a CRA notice has been sitting in an unmonitored My Business Account portal for four of those months.
Statistics Canada's 2025 data shows that 91.1% of Canadian employer businesses have between one and nineteen employees.[9] The overwhelming majority of businesses making this transition are doing it as solo founders or very small teams, without a dedicated operations person to manage it. The checklist approach below is designed for exactly this situation.
The solo mail solution stack
Step one: place a Canada Post Business Mail Forwarding order for twelve months before you vacate.
Step two: log into CRA My Business Account and update the physical address for each BN program account. While you are there, confirm that the notification email address is current.
Step three: update your GST/HST BN account address specifically, even if you already updated the main profile. They are separate records.
Step four: if you are NEQ-registered, update the Registraire des entreprises du Quebec within 30 days.
Step five: if you are federally incorporated, file Corporations Canada Form 3 within 15 days of the move.
Step six: update banking, insurance, and key vendor contact records.
Step seven: evaluate a virtual mailbox as your permanent registered address. The forwarding window closes in 12 months. A virtual mailbox address gives you a consistent street address that does not change when your working arrangements change again.
When using a home address creates new problems
A home address is technically permissible as the registered business address for many business types in Canada. But it creates its own complications that are worth understanding before you use it as the default.
Quebec's NEQ registry is publicly accessible. Any client, competitor, or curious party can look up your business address in the Registraire des entreprises du Quebec. Listing your home address there is a personal privacy decision, not just a compliance decision.
Google Business Profile also displays your registered address publicly in local search results and on Google Maps. A home address on GBP means anyone searching for your business can see where you live. A virtual mailbox address in Montreal lets you maintain a professional Griffintown address on GBP while keeping your home address out of public directories entirely. The difference in how your business appears to a prospective client before the first conversation is significant.
For more on the specific considerations around home-based business addresses, the 2727 article on using a home address for business covers the full landscape.

For 2-4 Person Teams: Managing Multiple Recipients and the Shared Mail Problem
The multiple-recipient problem that solo solutions do not solve
When your business has two, three, or four people, mail arrives addressed to multiple names. Canada Post forwarding follows the address: it redirects everything going to the old address to the new one. But if the team is now working from different locations, or if the "new address" is a personal home rather than a team workspace, that forwarding destination does not work the same way for everyone.
The practical problem is who receives the mail, who opens it, and who routes it to the right person. In an office, this happened naturally. In a distributed or remote setup, it requires an explicit decision about where mail lands and who handles it.
A virtual mailbox for your Montreal team solves this directly. The mail arrives at a staffed address, is scanned, and appears digitally in a shared portal that every authorized team member can access from wherever they are. The physical location of the forwarding destination becomes irrelevant because the content is available to everyone online.
The incorporated small team: your full registry update checklist
If you instead have a small team of two to four people that's federally incorporated and operating in Quebec, the minimum registry update count is more than you'd expect.
Corporations Canada: one filing (Form 3, 15-day deadline). Revenu Quebec: one update. NEQ/REQ: one update (30-day deadline). CRA My Business Account: one update per BN program account. If you have GST/HST, payroll, and corporate income tax accounts, that's three separate CRA updates, plus confirmation that the notification email address is current.
That's a minimum of six separate registry actions for a typical small incorporated team. More if your business has additional BN program accounts. Treating it as "one address change" is how gaps happen. Treating it as a checklist with six or more items, each checked off individually, is how it gets done correctly.
External links for each: Corporations Canada portal, CRA My Business Account, Revenu Quebec business portal, Registraire des entreprises du Quebec.
The transition period plan: who owns the mail
Designate one person as the mail owner for the transition period. This person is responsible for checking the Canada Post forwarding is active, scanning physical mail, and routing each piece to the right team member. If you are setting up a virtual mailbox, that person is also the primary account holder who sets up access for the rest of the team.
Set a calendar reminder at the 10-month mark to confirm that all registry updates have been completed and that no correspondence is still arriving at the old address. By month 12, the forwarding expires. If any registry still shows the old address, mail from that source stops at month 12 without warning.
For teams that still need occasional physical presence during the transition, a day pass or flex desk in Griffintown gives the team a place to work, meet clients, and receive any mail or packages that require in-person handling, without committing to a full office lease.
For 5-10 Person Teams: Building a Mail Protocol Your Whole Team Follows
Why individual solutions do not scale to a 10-person team
If you're leading a team of five to ten people, the mail transition is not a personal task. It's an operations task that requires a written protocol and a designated owner. Without one, the gap between "we said we would handle it" and "we actually handled it" tends to widen.
Montreal's Q1 2026 office market data from Colliers International shows an overall GMA vacancy rate of 17.2%, with Class B vacancy reaching 19.2% across the city. The softness is concentrated in lower-tier inventory while premium space has tightened to a 6.0% vacancy rate for Class AAA downtown. Teams in this size range are frequently the ones closing Class B offices during this cycle, often moving to coworking, hybrid arrangements, or lighter spaces rather than going fully remote. The mail transition is the operational step that makes the move clean.
At this size, you likely have an admin or EA who managed incoming mail at the old office. That person's responsibilities do not automatically extend to the new arrangement. Making it explicit who handles mail after the closure, and what the process is, is part of your transition plan.
The team mail protocol: what it covers
If this is your team, your written mail protocol should specify: who is the designated mail handler, where is the Canada Post forwarding order directed, who has login access to the virtual mailbox if one is set up, who owns each registry update on the checklist and what the deadline is for each, and when the 90-day check-in happens to confirm everything is live.
If you have an existing admin or EA, update their responsibility scope explicitly. The role description that covered "office mail" at the old office does not automatically translate to the distributed setting. Giving them the virtual mailbox credentials and the registry update checklist gives them clear ownership.
For teams considering a lighter physical presence rather than going fully remote, a private office in Griffintown provides a team hub and mail reception point without the overhead of a full corporate lease. The day pass options at 2727 also give team members on-demand access to professional workspace for the days they need to be in person.
The payroll address wrinkle
This is the registry update you're most likely to forget in the middle of a broader office transition.
Your CRA payroll BN account has a registered address that is separate from your business mailing address. This is the address CRA uses to send payroll audit notices, remittance processing confirmations, and T4 summary correspondence. Employees receive their T4s at their own home addresses, so the payroll account address does not affect individual T4 delivery. But it does affect where CRA sends business-level payroll correspondence.
If you close your office in the middle of a quarter and miss the payroll BN address update, you risk missing a remittance confirmation or audit notice. CRA will apply interest and penalties from the date the notice was sent, not from the date you eventually discover it. Update the payroll BN address in CRA My Business Account at the same time as the other program accounts, and confirm it separately.
When it makes sense to upgrade the address, not just forward it
At your size, the cost-benefit calculation for a permanent professional address shifts. One virtual mailbox that covers your entire team is less expensive than the fragmentation of managing mail individually for multiple people, and it gives your business a consistent registered address that works across all registries regardless of how your team's working arrangements evolve.
If your team is growing rather than contracting, a private office in Griffintown is worth considering seriously. The section below covers that scenario in more detail.

Virtual Mailboxes: The Durable Solution After Office Closure
What a virtual mailbox actually does
A virtual mailbox is a service where your business registers a real street address at a staffed facility. Physical mail addressed to that address is received, logged, and either scanned digitally for online access, held for pickup, or forwarded to another location. The address is a real street address, not a Post Office Box, which is the feature that makes it usable across government registries.
CRA requires a real street address for most BN program accounts. Corporations Canada requires a real street address for the registered office. The NEQ requires a real street address. A virtual mailbox satisfies all of these. A Canada Post PO Box does not.[2]
The scanning feature is what makes the service operationally useful for a distributed team. Mail that arrives at the address is scanned and available in a secure online portal. Every authorized team member can see every piece of mail from wherever they are working. For a Montreal business going remote or hybrid, this removes the dependency on anyone being physically present to receive and route mail.
Why the address location matters: Griffintown specifically
A virtual mailbox address in Griffintown carries neighbourhood-level credibility for Montreal-based businesses. Griffintown is Montreal's emerging tech and professional services district, positioned at the edge of Old Montreal and the downtown core, with direct STM bus access and a growing concentration of professional services firms, creative agencies, and tech companies.
For a solo founder or small team, the registered address on file with CRA, the NEQ, and Corporations Canada is one of the first signals a prospective client, financial institution, or new vendor checks. A Griffintown address signals an operational Montreal business. A home address or a postal code that does not match a commercial district signals something different, even if the business is doing excellent work.
This is not about optics for their own sake. It is about the practical friction that a non-commercial address creates in certain business relationships: banking applications, vendor terms, client due diligence, and professional association membership all involve address checks. A virtual office address in Montreal at a recognized commercial location removes that friction.
What to compare when evaluating virtual mailbox providers
When evaluating any virtual mailbox service, confirm these specifics before signing up:
Street address versus box number. Ask explicitly whether the address provided is a real street address with a suite number, or whether it is a PO Box formatted as a street address. For government registry purposes, these are not the same thing.
Scan quality and turnaround. Some services scan incoming mail the same day it is received. Others batch-scan weekly. For time-sensitive correspondence, same-day scanning matters.
Package handling. Most virtual mailbox services handle Lettermail. Not all handle parcels. Confirm explicitly what the service accepts and how you are notified when a package arrives.
Authorized names. Government correspondence, legal documents, and financial mail is addressed to specific people or the specific legal name of the business. Confirm how many authorized recipient names the plan supports.

Day Passes and Flex Desks: When You Still Need to Show Up
The partial presence problem
Some businesses closing their office still need occasional physical presence: a client meeting in a professional space, a document that requires in-person signing, a notarized document that needs to be picked up in person, or a package that requires a recipient to be on site. Fully remote does not solve these moments.
A full private office is too much for a business that needs physical presence two or three days a month. A day pass or flex desk covers exactly this use case: professional workspace available on-demand, without a lease commitment.
How a flex desk and a virtual mailbox work together
For a 2-4 person team going hybrid after an office closure, the combination of a virtual mailbox address and on-demand day pass access covers nearly everything a physical office address provided:
The virtual mailbox handles all incoming physical mail as a permanent registered address, with digital access for the whole team. Day pass access handles the occasional physical presence requirements: client meetings, package pickups, team working days, and any in-person tasks that remote work cannot accommodate.
The combined cost is significantly less than maintaining even a minimal private office. For teams where the driver of the office closure was cost reduction, this combination achieves the reduction while maintaining a professional Montreal address and physical access when needed.
What to look for in a flex space in Griffintown
Proximity matters for client-facing work. Griffintown sits at the boundary of Old Montreal and the downtown core, making it accessible from across the island and from the South Shore via the Champlain Bridge corridor. The neighbourhood's concentration of design, tech, and professional services firms also means that clients in those sectors are already familiar with it as a professional destination.
For on-demand coworking access, look for: conference room availability for client meetings (not just open-plan desks), reliable high-speed internet, and a booking process that allows last-minute reservations without penalty. For a business that needs to book a space the night before for a client meeting the next morning, flexibility in the booking model matters as much as the space itself.

Private Offices: When the Closure Was the Beginning of Something Larger
The business that closes one office to open a better one
Not every office closure is a retreat. Some teams close a lease that no longer fits because it is too big, in the wrong location, or in a building class that no longer matches where the business is going. They are not going remote: they are looking for a better space.
Colliers International's Q1 2026 Montreal data captures exactly this dynamic. The report describes the market shifting from "flight-to-quality" to a "fight-for-quality," as premium space has become scarce enough that top-tier landlords are experiencing activity across all their available spaces for the first time since the pandemic. Class B vacancy reached 19.2% GMA-wide in Q1 2026. Class AAA downtown vacancy sits at 6.0%.
A team closing a Class B office in a less desirable location is entering the soft part of the market as a tenant. The premium end, which includes well-positioned Griffintown private offices with amenities and professional services infrastructure, is competitive. Teams that have already closed their old office and are looking for a new space are entering that market as ready-to-move tenants, which is a strong position. The window for finding premium private office space in Montreal at reasonable terms is narrowing, not widening.
Private office versus home office and virtual mailbox: the practical comparison
For teams of five or more people, the cost of distributed work adds up in ways that are easy to underestimate: collaboration software, ad-hoc meeting room rentals when the home setup is not appropriate for a client, the productivity drag of isolation for team members who work better in a shared environment, and the overhead of managing a distributed team across multiple home setups.
A private office in Griffintown provides a team hub, a professional address, client meeting space, and mail reception in one monthly cost. For a team of five to ten people, the per-person cost of a well-sized private office often compares favorably with the aggregate cost of distributed work tools and occasional coworking or meeting room rentals.
The address is also a factor. A Griffintown private office provides a commercial address for CRA, Corporations Canada, the NEQ, Google Business Profile, and client-facing materials. It replaces the closed office's address across all of these registries with a single update.
The Master Checklist: What to Update, in What Order, by When
The 30-day timeline
This is the sequence that minimizes risk across all the registry types covered above.
Days 1 to 2: Place the Canada Post Business Mail Forwarding order for 12 months. Log into CRA My Business Account and update the physical address for each BN program account, plus confirm the notification email address. If federally incorporated, prepare and file Corporations Canada Form 3. The 15-day CBCA clock starts on move-out day.
Days 3 to 7: Update Revenu Quebec through the clic Sequr business portal. Update the NEQ/REQ entry through registreentreprises.gouv.qc.ca. (The 30-day deadline for the REQ gives you time, but earlier is better.) Update each business banking institution. Update Google Business Profile address. Update all team email signatures and the website contact page.
Days 8 to 30: Contact business insurance broker to update policy address. Update each professional association membership address. Notify accounts-receivable clients who pay by cheque. Update key vendor contact records. Update any subscription services that mail physical items.
The only hard legal deadline in this list is the 15-day CBCA deadline for federally incorporated businesses. Everything else carries real risk but not a hard statutory deadline. Treat the 15-day deadline as the drop-everything priority.
The ongoing watch list: months 2 through 12
Month 3: Confirm Canada Post forwarding is still active. Check My Business Account for any CRA correspondence posted since the move. Log in to Revenu Quebec to confirm no new correspondence has been sent to the old address.
Month 6: Do a full registry sweep. Log into Corporations Canada, CRA My Business Account (each BN program account), Revenu Quebec, and the REQ to confirm that all address records reflect the new address.
Month 10: Begin the final registry sweep before the 12-month Canada Post forwarding window closes. Any registry still showing the old address needs to be updated now. After month 12, there is no forwarding buffer, and Canada Post will not extend or renew.
Month 12: Forwarding expires. All registries must reflect the current business address, whether a new office, a coworking address, or a virtual mailbox in Montreal.
Keeping a documented update record
For each registry you update, record: the registry name, the date you made the update, and the confirmation number or screenshot reference. Keep this record somewhere accessible to more than one person on the team.
The reason this matters: CRA's June 2025 online mail transition means that correspondence is deemed received on the date it is posted to My Business Account, regardless of when the business reads it. If a dispute arises about whether a notice was sent to a valid address, a timestamped update record showing when you updated each registry is your evidence that the address you were notified at was one you had properly updated before the notice was sent.
This record is also useful for audits. CRA or Revenu Quebec audits sometimes surface notices from years earlier. Being able to show precisely when each address was updated, and what address was on file when each notice was sent, resolves those questions quickly.

Common Questions, Honest Answers
Can I use a family member's address temporarily?
Technically, using a family member's residential address as a temporary business registered address is permissible for some registry types. But it creates its own complications: it exposes that address in the publicly accessible NEQ registry, it creates a mismatch between the address your clients expect and the address on government records, and the "temporary" solution often becomes permanent through inaction.
The better path, at a comparable or lower cost, is a virtual mailbox. It provides a professional street address, keeps the family member's personal information out of public registries, and is explicitly designed for exactly this use case.
What happens if I miss the Corporations Canada 15-day deadline?
Missing the CBCA 15-day filing deadline for Form 3 does not trigger an automatic penalty in most cases. But it creates ongoing legal exposure: the old address remains the legally valid service address for your corporation until the update is filed. Any legal documents served at the old address during the gap between the actual move and the Form 3 filing are deemed delivered. If you have missed the 15-day window, file Form 3 as soon as possible rather than waiting further. The risk accumulates with every day the old address remains on file.
Does CRA auto-update when I update my NEQ?
No. CRA and the Registraire des entreprises du Quebec are completely independent systems. Updating one does not trigger any change to the other. The same is true for every pairing in the registry list: Corporations Canada and CRA, CRA and Revenu Quebec, Revenu Quebec and the NEQ. Three registries means three separate updates, with no automatic coordination between any of them.
Frequently Asked Questions
Does Canada Post forward all my business mail automatically when I close my office?
No. Canada Post Business Mail Forwarding covers Lettermail and Registered Mail within Canada. It does not cover any parcel services, prepaid reply envelopes, advertising mail, or mail at addresses shared by more than two businesses. Any piece marked "Do not forward" by the sender also stays at the old address. Forwarding is a useful buffer during the registry update period, not a complete solution.[1]
How long does Canada Post business mail forwarding last?
The maximum forwarding period for business mail is 12 months. There is no renewal or extension option after the 12-month window expires. Once it closes, mail addressed to the old address is returned to the sender or discarded. All registry updates and permanent address solutions need to be in place before that deadline.[1]
Does updating my address with CRA update my address with Revenu Quebec?
No. The Canada Revenue Agency (federal) and Revenu Quebec (provincial) are separate systems operated by separate levels of government. An address update with CRA touches nothing in the Revenu Quebec system. Both must be updated independently, through their respective online portals or phone lines.[7]
Can I use a PO Box as my registered business address after closing my office?
Generally no. CRA does not accept a Post Office Box or rural route number as the registered business mailing address for most BN program account types.[2] Corporations Canada similarly requires a real street address for the registered corporate office. A virtual mailbox provides a real street address that satisfies these requirements, where a PO Box does not.
How soon do I need to update my federal corporate registered office after moving?
Under the Canada Business Corporations Act, a federally incorporated business must file Form 3 with Corporations Canada within 15 days of the change of registered office. The filing is free, completed online, and takes approximately one business day to process. The registered office address cannot be a PO Box.[4]
What happens to CRA mail if I do not update my address?
As of June 16, 2025, CRA defaults to sending business correspondence online through My Business Account, not by paper mail. CRA considers this correspondence received on the date it is posted to the portal. If your My Business Account notification email is stale or inactive, CRA considers the document delivered even if no one from your business has seen it. Response deadlines, interest, and penalties run from that date. Updating both the physical address and the notification email address in My Business Account is essential.[3]
Can I get a professional Montreal address without renting a full office?
Yes. A virtual mailbox service provides a real street address at a staffed facility in Montreal for mail receipt, scanning, and portal access, without an office lease. 2727's virtual mailbox plans in Griffintown start at $35 per month for a basic mailbox with envelope photos and notifications, up to $165 per month for a Virtual Office plan that includes meeting room access and a dedicated phone number.
What is a virtual mailbox and how is it different from a PO Box?
A virtual mailbox provides a real street address at a staffed facility, where physical mail and packages are received, logged, and either scanned digitally or held for pickup. A PO Box is a numbered box at a Canada Post location. The critical difference for business purposes is that a real street address satisfies CRA, Corporations Canada, and NEQ registration requirements; a PO Box number does not. A virtual mailbox in Griffintown also presents as a professional Montreal commercial address in client-facing contexts, where a PO Box does not.
Do I need to notify anyone about my employees' T4 addresses when I close the office?
T4 slips are issued to employees at their own home addresses. The office closure does not affect individual T4 delivery. However, the business's CRA payroll BN account address determines where CRA sends business-level payroll correspondence: remittance confirmations, audit notices, and payroll program account correspondence. Update the payroll BN account address in CRA My Business Account at the same time as the other program accounts. The payroll account is a separate BN program record and must be updated independently.[2]
Does a virtual mailbox address work for Google Business Profile?
Yes, in most cases. Google Business Profile requires a real street address for local business listings. A virtual mailbox address at a staffed facility satisfies this requirement. Confirm with the provider that their address is not on any suppression lists in Google's system. Reputable virtual mailbox providers in established commercial locations handle this proactively. A 2727 Griffintown virtual mailbox address provides a recognized commercial Montreal location that works for GBP and for the local search visibility that comes with it.
