You would be claiming to have a permanent address in the U.S. while actually living in Canada. Wouldn't that be considered fraud?
When my wife and I got married (I'm American, she's Canadian), she had a credit card that was issued in Canada. When we called the credit card issuer, to give them her new address in the U.S., we were told that she had to close the account since she was no longer living in Canada. I would imagine that it would work the same way for you.
