How to Change a Registered Business Office in Canada

An outdated registered office means missed legal service and lost good standing. A summons served to your old address is still valid, so a corporation can lose a lawsuit by default. Here is the core answer: a federal corporation changes its address within the same province by a directors’ resolution and a free Form 3 filed with Corporations Canada within 15 days.

Changing the province itself is different. That requires Articles of Amendment (Form 4) and a special resolution of shareholders, then a companion Form 3 for the new street address. The 15-day deadline comes from Section 19 of the Canada Business Corporations Act (CBCA), which governs every federal corporation’s registered office.

What Is a Registered Office Address in Canada?

A registered office is the corporation’s official legal address for service of documents, including lawsuits, Canada Revenue Agency letters, and Corporations Canada notices. CBCA Section 19(1) requires a federal corporation to have a registered office at all times in the province specified in its articles, per the Justice Laws statute text. It must be accessible during normal business hours.

The address can be the company’s own premises, a lawyer’s or accountant’s office, or a registered office service provider’s address used with their consent. It stays bound to the province named in the articles.

What Is the Difference Between a Registered Office and a Head Office?

The registered office is the statutory legal address tied to the province in the articles under CBCA Section 19(1). The head office is where the business actually operates day to day and can be anywhere, including outside Canada. They can be the same address or different addresses.

A corporation can hold its registered office in Ontario while running operations from British Columbia. Corporate records such as the minute book and registers are typically kept at the registered office or another place in Canada designated by the directors.

Can the Registered Office Be a PO Box in Canada?

No. The registered office must be a physical civic address with a street name and number, city, province or territory, and postal code, per Corporations Canada’s Form 2 instructions, which state the address cannot be a post office box. A PO Box may be listed in addition to a physical location, never instead of one.

Who Approves a Registered Office Change Under the CBCA?

Directors alone approve any address change within the province stated in the articles, using a board resolution and Form 3. CBCA Section 19(3) lets directors change the place and address of the registered office within that province with no shareholder vote. A special resolution of shareholders (a two-thirds majority) is required only when the province itself changes.

Type of changeApproval neededFilingSource
Same city, same provinceBoard resolutionForm 3 within 15 daysCBCA s.19(3) / Corporations Canada
Different city, same provinceBoard resolution only (no shareholders)Form 3 within 15 daysCBCA s.19(3)
Different provinceSpecial resolution of shareholders (two-thirds)Form 4 + Form 3CBCA s.173(1)(b) / Corporations Canada

The two-thirds threshold comes from the CBCA definition of a special resolution as a majority of not less than two-thirds of the votes cast, per Section 2 of the CBCA. The board resolution records the new address, effective date, and authorization to file, and it stays in the minute book rather than being filed with the government.

How Do You File Form 3 With Corporations Canada? (Step by Step)

File Form 3 online through Corporations Canada’s Online Filing Centre, free of charge and usually processed within one business day, per the Corporations Canada fee and processing schedule. Email and mail are slower alternatives. Follow these steps in order.

  1. Pass the board resolution authorizing the change and naming an officer to file.
  2. Verify the new address is physical, in-province, accessible, and yours to use.
  3. Complete Form 3 with the corporation name, corporate number, new complete address, effective date, and authorization details.
  4. Submit through the Online Filing Centre.
  5. Keep the confirmation Corporations Canada issues.
  6. Verify the update on the Federal Corporation Search database.

The official Form 3 (Change of Registered Office Address) is the prescribed form under CBCA Section 19(4) and confirms a street address is required.

How Do You Change the Registered Office to a Different Province?

File Form 4 (Articles of Amendment) after a special resolution of shareholders to change the province named in the articles, then file Form 3 to set the actual street address in the new province. That is two filings for two distinct purposes, per Corporations Canada’s guide to amending articles.

Form 4 costs CAD $200 online with one-business-day processing, or CAD $250 by email or mail with 10-day processing, per the Corporations Canada fee schedule. A four-hour express option adds CAD $100. Changing province may also trigger updates to your extra-provincial registrations, so plan for that knock-on effect.

What Is the 15-Day Rule for Registered Office Changes?

The CBCA requires notice of a registered office address change to reach the Director within 15 days of the change. CBCA Section 19(4) states the corporation shall send the Director a notice, in the prescribed form (Form 3), within fifteen days of any change of address, per the Justice Laws text.

This deadline is federal and applies to CBCA corporations. Provincial statutes set their own registrars, forms, and timelines.

Do You Need to Notify the CRA of a Registered Office Change?

Yes, separately. Corporations Canada does not automatically update the corporation’s address with the Canada Revenue Agency (CRA). Update the address through CRA My Business Account or by phone, not by filing Form RC1, which registers a new Business Number rather than changing an address.

Check each Business Number (BN) program account individually, since GST/HST, payroll, and corporate income tax accounts can each carry their own address. Corporations operating in Québec should also update Revenu Québec.

Who Else Do You Need to Notify After the Change?

Notify the extra-provincial registries in every province where the corporation is registered, plus the CRA, banks, insurers, and key counterparties. A federal corporation registered extra-provincially must keep those filings current, a step many businesses miss entirely.

Revenu QuébecUpdate Québec tax accounts if registeredVaries, check registrarRevenu Québec
Banks and insurersKnow Your Customer (KYC) records and correspondencePer institution policyInstitution policy

Missing any of these can delay filings or interrupt banking and licensing relationships.

What Are the Penalties for Not Updating Your Registered Office?

Missing the 15-day notice puts the corporation in default with Corporations Canada. Continued non-compliance across notices and annual returns can lead to loss of good standing and, eventually, dissolution for default. Dissolution is the end of a chain, never an instant trigger from one late filing.

The real risk is legal service. A summons served at the old registered address is deemed effective, so a corporation can lose a lawsuit by default because it never saw the documents.

What Are the Most Common Mistakes When Changing a Registered Office?

The most common mistakes are procedural failures that a compliance-literate team can avoid. Each one maps to a specific step in the CBCA process. Fix them before you file.

  • Missing the 15-day notice window under CBCA Section 19(4).
  • Listing a PO Box instead of a physical civic address.
  • Filing Form 3 when a province change needs Form 4, or forgetting the companion Form 3 after Form 4.
  • Assuming Corporations Canada tells the CRA automatically.
  • Forgetting extra-provincial registration updates.
  • Failing to record the change in the minute book.

Registered Office Change Checklist for Corporate Secretaries

Work this checklist in sequence to keep the change clean and auditable.

  • [ ] Pass a board resolution, or a special resolution of shareholders if the province changes.
  • [ ] File Form 3 (and Form 4 first if the province changes) with Corporations Canada.
  • [ ] Save the confirmation from Corporations Canada and verify on Federal Corporation Search.
  • [ ] Update the CRA and every BN program account (GST/HST, payroll, corporate income tax).
  • [ ] Update extra-provincial registries and Revenu Québec where applicable.
  • [ ] Notify banks and insurers.
  • [ ] Record the change in the minute book with the effective date.
  • [ ] Update stationery, invoices, and the website footer.

Should You Outsource Your Registered Office Change?

Corporations with multiple jurisdictions or no in-house company secretary commonly use corporate secretarial or managed registered office services. These providers supply a compliant service address and handle the filings, including the CRA cascade and extra-provincial updates.

The honest counterpoint: a single-entity corporation with a stable address can file Form 3 itself for free in minutes through the Online Filing Centre. Outsourcing earns its keep when the number of jurisdictions or entities grows.
