If you can't redeem your gift card in the App Store or iTunes ...*

*Code must be redeemed in a different country or region

If you see a message that says the code must be redeemed in another storefront, the card was probably purchased in another country or region. You can't redeem Apple Gift Cards or App Store & iTunes Gift Cards outside of the country or region of purchase. For example, if you bought an App Store & iTunes Gift Card in France, you can't redeem it in the App Store in the United States.

If you need more help, contact Apple Support. <<<Try contacting Apple? You could always sell it to someone in Canada who could use it.

Since the two stores are apparently independent of each other (you cannot buy Canadian items from the US store) then I suspect they cannot exchange them since they would not have the Canadian equivalent in the US store. You are welcome to contact Apple but my earlier post seems to pretty clearly state their position on this.

Refer to this document for ways to contact Apple --> Choose your country or region - Official Apple Support

Select your country (also look for "other" regions), then a product. If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.

or:

Contact Apple for support and service by telephone --> Contact Apple for support and service - Apple Support
