Effective November 3, 2025, most new CRA business number registrations and additions of program accounts must be completed through Business Registration Online (BRO).

Exceptions requiring phone or paper registration:

• Reactivating a previously closed account
• Businesses with only non-resident owners
• Businesses owned by another business (e.g., corporations or partnerships)

Action: Expect online registration to be the default and plan accordingly when setting up new entities or accounts.
