How do I change the address information on my Apple ID from the US to Canada?
Change your iTunes Store country or region - https://support.apple.com/HT201389 - In small, faint print, "You might not be able to redownload some of your purchases from your original country or region." This may also mean any subscription services you use may no longer work (e.g., Apple Music).
