ElliotTwo lawyers...what a recipe for a disaster. 
As a Canadian, i sort of understand what the purchaser was driving at, although i deplore his tactics. So many sellers jack up the shipping costs to Canada then only put the cards in a regular envelope (which only costs a few cents more than shipping within the U.S.).
PayPal is also a problem for us Canadians, as our addresses can not be confirmed, fortunately most sellers do not seem to be concerned as long as we have good feedback.
The purchaser, since he buys frequently from the U.S., should have a bank account set up at a U.S. bank, since he is correct that sometimes it takes quite long for cheques drawn in Canada to clear. Additionally, if i was a U.S. seller i would refuse to accept these cheques as it is quite possible that my bank would charge me a fee for clearing the cheque.
I think the real problem here has nothing to do with the Canadian/U.S. issue, but rather the purchaser just being "one of those types of buyers" that we all run into. Also, Adam is one of those guys who gets his back up quickly. (Adam, you know I love ya)
