Amending or cancelling an Ontario Business Name registration

To ensure the Public Record is accurate, you must notify the Central Production and Verification Services Branch when the information in your registration has changed. Changes in address, business activity or partners (as long as one of the original partners remains the same), must be filed on the Ministry form within 15 days after the change. There is no filing fee. However, changing the name of your business registration is considered a new registration and the relevant fee applies. Changing the type of registration, e.g. a partnership registration to a sole proprietorship, or changing all the partners in a partnership, is also considered a new registration.

If the business ceases to operate, you should cancel your business name registration. There is no filing fee for the cancellation of a business name.

The amended or cancelled registration can be submitted to the Branch by mail or in person at the Public Office in Toronto. Alternatively, the registrant can amend or cancel a business name registration online through the ServiceOntario website at Ontario.ca. The registrant will receive confirmation of the changes by mail in approximately three weeks.
