A bill of sale as parts will work but depending on the particular crossing people what makes it parts and not a whole can vary. I've heard of people being denied if the whole vehicle is present, dissassembled or not. Others apparently have come through with cut in half frames. As far as I know the exemption should apply regardless the form, but a whole vehicle will still need a showing of it's origin. That means a title from oone of the Canadian provinces.
