This is because they think American tourists have to do it in the USA so they expect to do it everywhere they travel. They don't realize that we don't do that in Canada and class us all as North Americans.Maybe some day they will figure it out and realize that most countries don't require that for security anymore.It was comical to see a man lose his pants when he removed his belt, and then have to walk through in his underwear and bare feet! He was just a tad embarrassed.(no pun intended)
