ORIGIN Gift Card USD Usable in Canada?

First off sorry if this is the wrong topic, but anyway this is a simple "yes" or "no" answer I cannot find anywhere, here is my problem.

So I currently want to buy the Battlefield 1 Premium which costs $65.99 here in Canada (I live in Canada), before taxes. My problem is, I buy video games with visa gift cards and right now I currently have 2 cards, one being $34.86 and the other being $48.64 which = $83.50 total. Now since Origin is not Steam, and for some reason you can't simply add funds to your account with a credit card, and ONLY add funds with a stupid origin gift card (that aren't even available in CAD for some other stupid reason) it seems as if I cannot buy Battlefield 1 Premium. However I could buy a $20 USD ($27.06 CAD) Origin card KEY from walmart with my $34.86 card for example, which is actually about $27 CAD value instead of "$20" which would mean I would have $27 (assuming the conversion works correctly) on my account, then I could just use my $48.64 card to finish off the purchase.

So really what I'm asking is, If I have possession of a ORIGIN Gift Card from USA with USD on it when I live in Canada, with a Canadian IP, on a 100% Canadian account, would I be able to redeem the US Gift card on my Canadian account, or will it be declined due to me using a Canadian account?
