Ontario Articles of Amendment: change your corporation
The filing that changes what's in your articles of incorporation.
Verified. Last reviewed 2026-10-05. Always confirm with the official source before filing.
Step by step
- Pass a special resolution. Shareholders approve the change, usually by two-thirds of votes cast or in writing by all shareholders.
- Get a NUANS report if changing to a word name. A new word name needs an Ontario-biased NUANS report dated within 90 days.
- File in the OBR. Sign in with your company key and file Articles of Amendment. The fee is shown at checkout.
- Update your records. Put the certificate of amendment in your minute book and update CRA, your bank and your licences.
Changes that need Articles of Amendment
- Changing the corporate name, including from a number to a word name.
- Adding, removing or changing share classes or their rights.
- Changing the number of directors set in the articles.
- Adding or removing restrictions on business or share transfers.
Changes that don't
Changing directors, officers or your registered office address is done with a Notice of Change, not Articles of Amendment.
Frequently asked questions
How do I change my numbered company to a name?
Get an Ontario-biased NUANS report for the new name, pass a special resolution, then file Articles of Amendment in the OBR.
Do I need a lawyer?
Not legally. Simple name changes are often filed directly. Share-structure changes have tax and legal effects worth reviewing with a professional.
Do I need to tell the CRA?
Yes. Update your business number records with the CRA after a name change.
