If you want to incorporate your business, depending on whether you want to incorporate provincially, territorially, or federally, you should contact your provincial incorporating authority, or Industry Canada-Strategis.
When you incorporate with the province of Ontario, Manitoba, British Columbia, Nova Scotia, New Brunswick, or Industry Canada your business will automatically be registered for a Business Number (BN) and a corporation income tax program account.
Within 45 days of incorporation, you should receive a notice confirming your BN and summary of program accounts.
If you require your BN before we send you the confirmation notice, contact us at 1-800-959-5525. Have a copy of your certificate of incorporation on hand, since we may ask you for it.
When you incorporate with any other province or territory you will have to register for a BN and corporate income tax program account by contacting the CRA. For more information, go to How to register.
Non-resident corporations that register for a Business Number with CRA will also be registered with a corporate tax account.
