To change your province of residence, you will need to submit a T1-ADJ form to the Canada Revenue Agency (CRA). The T1-ADJ form is used to make adjustments to your tax return, including changing your province of residence. You can download and print the T1-ADJ form from the CRA website: T1-ADJ T1 Adjustment Request. Complete it, and mail it to the CRA.
For faster service, submit your request electronically using Change my Return in My Account or ReFILE. Once you have logged in, select "Change My Return" and then "Change My Answers". You will then be able to update your primary residence.
For more information please visit the CRA website: T1-ADJ T1 Adjustment Request.
