It is working exactly as designed, even if you as a passenger don’t like it (yes - it can be annoying, but can have its advantages, at times, as well).

are you talking about a workaround for an upgrade specifically, or just to buy a ticket? If it’s just buying a ticket, you can go to a Canadian OTA to buy the ticket at the Canadian price and they (at least most), will accept a US (or foreign) card payment.

if it’s for an upgrade, I’m not sure there’s a workaround.
