None whatsoever. When I started ordering parts from America around 1972, I spent a lot of time and money at Canada Customs, getting my parcels cleared. At one point in that history, our dollar dropped to 55 cents against the USD so you can imagine what that was like. Now, parts come straight to my door, delivered by a gorgeous 22 years old blonde woman, with a smile. I love getting parcels from America!! And our dollar is nearly at par.
