Have already filed my return but need to change address and cant do online via CRA?

 

Getting started

You can't use ReFILE to make changes to personal information on page 1 of an income tax and benefit return, such as your address.

 

This Canada Revenue Agency (CRA) page shows you all the ways you can update your address with them: https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/change...
