<human>: Hi, I'm curious if anyone knows how strict the ban on Americans traveling to Cuba is. I'm an American citizen attending a Canadian school and got asked to go on a brief (1 week) trip to Cuba for reading week and heard Americans sometimes go through Canada and just don't stamp their passports. But it clearly says on the Department of State's [site] that the American govt will confiscate my passport if they figure out what I'm doing. Just wondering how strict this is, and if the stories I heard about the rules being pretty lax are true or really just stories.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: OP wants to know if the embargo on Americans traveling to Cuba through Canada is strictly enforced. If anybody has ever done so then please PM me
