Amazon.ca: view your gift certificate balance

Very strange; amazon.ca doesn’t officially let you see your gift certificate balance (though they claim you can from the help pages). You can see your balance if you go here: https://www.amazon.ca/gp/css/account/payment/view-gc-balance.html. (You might want to copy the URL and paste it so you can see there’s no trickery going on when you are asked for your password.)

This is just the amazon.com balance page with the .com changed to .ca, but there’s no link from the Your Account page.
