i think shawn i would just call canada customs.or better yet your right there in windsor go over to canada customs where all the trucks go after crossing the border.they are right off of huron church.head down there just don't go in where the trucks go with your car.then when you walk in the building just go down to the main counter and wait there and ask for the panflet explaining duty,and ask a customs agent directly if you pay duty on a sled.just explain your trying to find out before you buy down there.also be very polite to the officers in there,they tend to be a little moody. and please let us know what you found out,as there are probably alot of folks curious about this. THANKS MAN
