It would be nice, though, if there were disclaimers about this when you book a ticket to Canada. I've known several people who got turned away when they got there and had no idea it would come up. If they had known, they wouldn't have bothered. An ex-boyfriend of mine was heading there to be a university exchange student and got turned away for a very minor shoplifting offense when he was like 18. He was stupid to shoplift, and Canada had every right to turn him away, but he had planned a whole semester through a university foreign exchange program and then was SOL. You'd think it would have been part of the program orientation packet or something.
