Starting in spring 2025, the Canada Revenue Agency (CRA) will transition to online mail as the default method of delivering most business correspondence. This means you’ll start receiving most of your business notices and other correspondence through the CRA’s secure online portal, My Business Account, instead of by mail.

As we celebrate Small Business Week from October 20 to 26, the Canada Revenue Agency (CRA) is here to support Canada’s small business community. This week is dedicated to helping you connect, learn, and grow your business knowledge. We’re excited to share tax resources, tools, and services to help you tackle the challenges of running a business and keeping your tax affairs in check.
