Starting in May 2025, the Canada Revenue Agency (CRA) transitioned to online mail as the default method of delivering most business correspondence. This means you now receive most of your business notices and other correspondence through the My Business Account portal in your CRA account, instead of by paper mail.
This change applies to all of the following businesses:
-New business number and CRA program account registrations
-Existing businesses already registered for My Business Account
-Existing businesses who have given online access to an authorized representative, who can view or modify information on their behalf in Represent a Client
