How do I change my address with CRA?

Log in to the CRA My Account service and click 'Change my address and phone numbers' under Related Services. You can also contact the CRA directly by calling 1-800-955-8281. Alternatively, you can change the mail address by completing and submitting Form RC325 Address Change, or send a signed letter to the CRA that includes your SIN#, new address, and moving date.
