Well I dunno.. but the guy who took the Mercury out of my lawn didn't have any paperwork other than his printout of the eBay auction before he took the car. He just showed them the sales reciept for the car at the border (a handwritten, non notorised reciept) and into the great white north he went with no problem. This was just last fall. He did tell them it was a parts vehicle.
I suspect had he had a new BMW on a trailer they might have asked him more questions, but this was a old 1970 car with mismatched tires on it and no motor.
