What kinda of part, size, weight, etc. If you paid for it and had it shipped to a Canadian member on here then he or she could forward it to you. I know it sounds like a lot of trouble and of course extra shipping costs but it depends on how bad you want/need it. Another idea, maybe you can get them to ship to a company in the Toronto Ontario area called "cross boarder pick up". They have a depot on both sides of the boarder and you could have them ship or you pick it up from there. Again extra work and money. Let me know if you want more info.
Good luck
