What Happens to Your Business Address If You Cancel Your Coworking Membership
If your coworking membership is also the address on your incorporation papers, your tax accounts, and the letterhead your clients see, canceling that membership is not just a workspace decision, it is an address change that touches government registries, tax authorities, your bank, and every piece of mail heading your way. This guide walks through exactly what happens on paper when you leave a coworking space that doubles as your registered business address in Quebec: what the Registraire des entreprises du Québec (REQ) requires, what changes federally through Corporations Canada if you are incorporated that way, how to update Revenu Québec and the Canada Revenue Agency (CRA), what actually breaks if you miss a deadline, and how a standalone virtual mailbox can keep your address stable no matter what happens to your desk.
Executive Summary
Quebec-registered and Quebec-incorporated businesses must file a current update declaration with the Registraire des entreprises within 30 days of any change to information on file, including a change of address, and filing that declaration is free [1].
Federally incorporated businesses have a shorter window: under the Canada Business Corporations Act, a corporation must send Corporations Canada a completed Form 3 notifying it of a change of registered office address within 15 days of the change [5].
Failing to keep your Quebec enterprise file current is not a paperwork footnote, an enterprise that misses two consecutive annual updating declarations or fails to respond to a Registraire notice can be struck off ex officio, and for a Quebec-constituted legal person that striking off triggers dissolution [3].
Revenu Québec and the CRA each require a separate address update, updating one government file does not automatically update the others, and both agencies offer free online tools to make the change [8][9].
Canada Post's mail forwarding service is a useful short-term bridge, but it only redirects physical mail, it does not update your address with any of the organizations sending that mail, and it does not forward parcels [12].
A standalone virtual mailbox, the kind that runs independently of any desk or office booking, can keep your registered address stable through a membership cancellation, a move, or indefinitely, since it is not tied to whichever workspace tier you happen to be using [13].
Why This Question Deserves a Straight Answer
Plenty of small businesses, freelancers, and consultants in Montreal use their coworking address for more than a return address on invoices. It is often the domicile address filed with the REQ, the registered office on incorporation documents, the address the CRA and Revenu Québec have on file, and the address printed on contracts. That is a completely normal and legal thing to do, a real coworking or virtual office address, unlike a P.O. box, is an acceptable domicile for Quebec business registration purposes. The complication shows up when the membership ends: your desk goes away, but your business still needs a valid, current address on file with four or five different institutions at once, and none of them find out automatically. Each one needs to be told separately, on its own timeline, or the mail that matters most, tax notices, legal notices, corporate compliance reminders, keeps arriving at a mailbox you no longer have access to.

If Your Business Is Quebec-Incorporated or Registered: The Registraire des Entreprises (REQ)
Every business registered in Quebec's enterprise register, whether it is a sole proprietorship, a general partnership, or a Quebec-incorporated company, has an ongoing legal obligation to keep its file current. When something changes, including your address, you are required to file a "déclaration de mise à jour courante" (current update declaration) within 30 days of the change, and this filing carries no fee [1]. This is separate from your annual updating declaration, which every registered enterprise must file each year regardless of whether anything has changed, sole proprietors eligible for joint filing have until June 15 to file it, while corporations eligible for joint filing generally have up to six months after their fiscal year end [2]. If your address changes between annual filings, the 30-day current update declaration is the mechanism that keeps your file accurate in the meantime, and it is filed online through "My Office" (Mon dossier), under business management [4].
It is worth being precise about what this filing does and does not do. Updating your address at the REQ changes the public record for your business, the address that anyone searching the enterprise register will see. It does not, on its own, change your address with Revenu Québec, the CRA, your bank, or anyone else, each of those needs its own update, covered below.
What Happens If You Do Not Update in Time
This is the part worth taking seriously rather than filing away as an eventual to-do. An enterprise that fails to file two consecutive annual updating declarations, or that fails to comply with a request from the Registraire within the prescribed period, can be struck off the register ex officio [3]. For a legal person constituted in Quebec, that striking off is not a slap on the wrist, it results in dissolution: the company stops existing as a legal entity, which immediately complicates bank accounts, active contracts, and any ongoing legal proceedings. A struck-off business can apply to the Registraire for revocation of the striking off, but that route means filing every missing declaration, paying accumulated fees and penalties, and paying a separate fee for the revocation request itself. An outdated address does not by itself cause this outcome overnight, but it is very often the reason a business misses the notices that would have let it catch a problem before it escalated to that point, which is exactly why the 30-day window exists in the first place.
If Your Business Is Federally Incorporated: Corporations Canada
If you incorporated federally under the Canada Business Corporations Act rather than provincially in Quebec, the process and the deadline are both different, and the deadline is tighter. Subsection 19(4) of the CBCA requires a corporation to notify Corporations Canada of any change to its registered office address within 15 days of the change, using Form 3, Change of Registered Office Address [5]. Form 3 asks for the corporation's name and corporate number, the new complete street address (a post office box is not acceptable on its own), and the effective date, and it needs to be signed by a director, an authorized officer, or an authorized agent of the corporation [7]. There is no fee to file it, and it can be submitted through Corporations Canada's Online Filing Centre, where it is typically processed within a business day.
One wrinkle worth flagging if you are relocating out of Quebec entirely: if your new registered office moves to a different province or territory than the one named in your articles of incorporation, a Form 3 alone is not enough. You also need to file Articles of Amendment (Form 4) to change the province named in your articles, following a special resolution of your shareholders, before or alongside updating the specific street address.
Federal incorporation also carries its own version of the compliance risk described above for Quebec entities. Every CBCA corporation must file an annual return, and Corporations Canada's stated policy is to dissolve a corporation that has not filed for two years, sending a final notice first and generally giving 120 days to catch up before issuing a certificate of dissolution [6]. An address that is no longer current is one of the more common reasons that first notice never reaches the people who need to see it.

Updating Your Tax Accounts: Revenu Québec and the CRA
Corporate registration and tax registration are handled by entirely separate systems, so updating your address at the REQ or with Corporations Canada does not touch either tax authority's records.
Revenu Québec maintains its own address on file for every registered business, and it explicitly asks businesses to inform it "as quickly as possible" whenever that address changes. The most direct route is the online change-of-address service in "Mon dossier" for businesses, and if your business is registered for clicSEQUR-Entreprises, the "Zone entreprise" version of that service can notify Revenu Québec along with several other Quebec government departments and agencies in a single submission [8]. If you would rather not go through the online portal, a paper Notice of Change of Address (form LM-1.AD) works as well. Usefully, Revenu Québec allows you to submit a change of address up to 180 days in advance, so if you already know your coworking membership is ending on a specific date, you do not have to wait until moving day to file.
On the federal side, the CRA's "Manage address" service inside My Business Account is the fastest way to update your mailing address, physical address, and books-and-records address if you are the business owner or hold the right level of account authorization [10]. If you cannot or would rather not use the online account, the CRA also accepts address changes by phone through its business enquiries line, or by mailing in Form RC325, Address Change Request [9]. Getting this one right matters more than it used to: starting in May 2025, the CRA made online mail through My Business Account the default way it delivers most business correspondence, so an outdated address is less likely to mean a lost paper letter and more likely to mean you never realize there is mail waiting in a portal tied to an account you are not checking [11].
What Actually Breaks If You Do Not Update in Time
Pulled together, here is the practical version of what is at stake, roughly in order of how much it tends to hurt:
Missed statutory notices. Both the REQ and Corporations Canada send default notices and compliance reminders to the address on file before taking any serious action. If that address is a coworking mailbox you no longer have access to, you may not see the warning that precedes a striking off or dissolution until it is already underway [3].
Missed tax correspondence. Revenu Québec and CRA notices, assessments, and audit correspondence go to whatever address is on file, and with CRA increasingly delivering notices online rather than on paper, an address problem can compound into a login-and-notification problem [11].
Good-standing and compliance risk. A struck-off or dissolved corporate status shows up publicly on a registry search, which is exactly the kind of thing a bank, a landlord, or a prospective client checks before signing anything with you.
Missed legal notices. Contracts, lawsuits, and formal legal notices are frequently served to the registered or domicile address on file with the corporate registry, not wherever you happen to physically be working that week.
Everyday friction. Beyond the serious risks, an outdated address quietly breaks smaller things too, bank statements, insurance renewal notices, supplier invoices, and courier deliveries that show up at a desk you no longer rent.

Canada Post Mail Forwarding: A Bridge, Not a Fix
If you are moving your physical location, Canada Post's mail forwarding service is worth setting up regardless of what else you do, since it catches mail sent to your old address during the transition. You can start or manage the service through your Canada Post account online or at a post office, and for a business relocation, online orders can take effect as early as 10 days after purchase [12].
Two limitations matter enough to plan around. First, the service forwards letter mail, it does not forward parcels, so a courier delivery to your old coworking address will not automatically find its way to you. Second, and more important for the concern in this guide, mail forwarding only redirects what is already addressed to your old location, it does nothing to update your address with the REQ, Corporations Canada, Revenu Québec, the CRA, your bank, or anyone else sending you that mail in the first place. Think of it as a safety net for the transition window, not a substitute for actually updating your records with each institution.
Using a Virtual Mailbox to Keep Your Registered Address Stable
This is the piece that solves the underlying problem rather than just managing its symptoms. A standalone virtual mailbox is a business address subscription that runs independently of any desk, dedicated seat, or office lease, which means canceling a coworking membership does not have to mean losing the address you built your registration, your bank account, and your client-facing paperwork around.
2727 Coworking's own Mailbox plan, starting at $35 a month, is exactly this kind of product: a real, physical Griffintown business address with mail receipt, pickup, and notifications, sold as its own subscription rather than as a feature bundled into a desk membership [13]. That structure means two different situations are both covered by the same product. If you are canceling a coworking membership but want to keep the same registered address, you can downgrade to the Mailbox plan on its own and keep the address you already filed with the REQ, Revenu Québec, and the CRA exactly as it is, no update filings required anywhere, because the address itself has not changed. Or, if you are leaving Montreal coworking altogether but still need a legitimate, mail-capable Quebec address for registration purposes, a virtual mailbox can serve as that address indefinitely, independent of whether you ever book a desk again. 2727's fuller guide to virtual offices in Montreal walks through how mail handling and address registration fit together in more depth (Virtual Office in Montreal: The Complete Guide).
The one-week move-in and roughly one-month move-out expectations that apply to 2727's desk-based memberships are covered in detail in a separate guide, worth a look if the timing of your cancellation itself, not just the address consequences, is the part you are trying to plan around (How Much Notice Do You Actually Need to Move Into or Out of Coworking Space?).

The Offboarding Checklist: What to Update, in Order
If your coworking membership is ending and it was also your registered business address, this is roughly the order of urgency, weighted toward the items that carry a legal deadline or a compliance consequence first:
Corporate registry. File your current update declaration with the REQ within 30 days of the address change if Quebec-incorporated or registered, or Form 3 with Corporations Canada within 15 days if federally incorporated. These carry actual statutory deadlines, everything else on this list does not.
Tax authorities. Update Revenu Québec (online, or via form LM-1.AD) and the CRA (My Business Account, phone, or Form RC325). Do this as soon as you know your move-out date, Revenu Québec accepts changes up to 180 days ahead of time.
Bank and payment processors. Business bank accounts, merchant accounts, and payment processors often use your registered address for verification and statements, and a mismatch can flag account reviews.
Business insurance. Your policy is typically written against a specific business address, tell your broker or insurer before the old address goes cold, not after a claim depends on it.
Active contracts and clients with formal notice clauses. Some commercial agreements specify that legal notices must go to a stated address, if yours does, update it explicitly with each counterparty rather than assuming they will notice from an invoice.
Suppliers and recurring billers. Anyone shipping physical goods or mailing paper invoices to your old address needs the update directly, this will not happen automatically just because you changed your government filings.
Google Business Profile and local listings. If your coworking address ever appeared on a Google Business Profile, directory listing, or website, update or remove it so customers and delivery drivers are not sent to a desk you no longer occupy.
Letterhead, invoice templates, and email signatures. The lowest-risk item on this list, but also the easiest to forget, and the one most likely to embarrass you in front of a client months later.
Canada Post mail forwarding. Set this up as a safety net that overlaps with your move, not as a substitute for the steps above, it catches what falls through the cracks while everything else gets updated properly.
Frequently Asked Questions
Do I have to update my address with the REQ if I only move within the same coworking building or a different unit at the same operator?
Yes, if the actual street address or suite number on file changes, the REQ's 30-day current update declaration requirement applies regardless of how far you are moving, even a short move within the same building.
Can I keep my old coworking address as my registered address after I cancel my membership?
No, once you no longer have the right to receive mail at that address, it should not stay on file as your domicile or registered office, doing so risks mail from the REQ, Revenu Québec, or the CRA arriving somewhere you cannot retrieve it, which is precisely the situation that leads to missed compliance notices.
If I update my address with the REQ, does that automatically update it with Revenu Québec and the CRA?
No, unless you use Quebec's "Zone entreprise" combined change-of-address service (available if you are registered for clicSEQUR-Entreprises), each government body maintains its own address record and needs to be told separately.
What is the fastest way to avoid any gap in my registered address?
Set up your new address, whether a new physical location or a standalone virtual mailbox, before your coworking membership actually ends, then file the REQ, Corporations Canada, Revenu Québec, and CRA updates in the same window rather than waiting until after the old address is already gone.
Can a virtual mailbox be my permanent registered business address, not just a temporary bridge?
Yes, a virtual mailbox that provides a genuine physical address capable of receiving mail satisfies the same requirements a coworking or office address does for REQ and Corporations Canada registration purposes, and there is no rule requiring it to be temporary.
What actually happens if I just let my old coworking address sit on file after canceling?
Nothing happens immediately, but you are exposed: any notice, tax correspondence, or legal document sent to that address goes to a location you can no longer access, and for a Quebec-incorporated entity, enough missed correspondence can eventually lead to an ex officio striking off and dissolution.
Does Canada Post mail forwarding count as updating my address with the government?
No, it only redirects physical mail that is already addressed to your old location, it does not change your address of record with the REQ, Corporations Canada, Revenu Québec, or the CRA, each of those still needs its own separate update.
If keeping a stable business address feels like the part of canceling a coworking membership you would rather not think about again, 2727 Coworking's virtual mailbox plans, starting at $35 a month, let you decouple your registered address from whichever workspace you use, or stop using, entirely. Call (438) 796-0017 or visit 2727 Coworking to set one up before your current membership ends.
