We have crossed the border in and out of Canada seven times and never been asked about ownesrhip and, our camper doesn't have the license plate from the truck mounted either. Seems when you call about such things they give you the best sounding answer but when at the border they're worried about fruits and vegetables. We carry our dog and have always had the wellness papers but have never been asked about them either. I would be worried about an unpapered shotgun. They always ask if you have any guns going into Canada.
