Yeah I had that problem before also. I was going to purchase a S2000 from the states a while ago however they said warrenty would be void. Couple of people in another forum actually went through this and said warrenty was void. I called couple dealears and they all said if US will honor it, then we will. Basically US would have to send over all the paper work and permission to the Canadian dealers saying this car/guy is worth the warrenty. However this was honda.

Maybe I'll also call a couple other dealerships here in Edmonton and see what the answer is. The first dealer I called just said yes very quick, he said the warrenty is valid in all of North America, but perhaps he didn't think about selling the car and making money off of it.
