Filing Common-Law for 2022 Personal Tax Return - Actual Date of Becoming Common-Law or When the Change Was Made on CRA My Account?

Hello, 

If I started living with my partner on Dec 15, 2021 and technically became common-law on Dec 15, 2022 but changed my marital status on CRA My Account on Jan 13, 2023, do I file the 2022 personal tax returns as common-law? Or would I be filing as a single because I made the change on CRA website on Jan 13, 2023? Or is it still common-law as at Dec 31, 2022 because the effective date that I actually lived with my partner for 12 months is Dec 15, 2022?

Thank you.
