What would happen if I enter Canada without a passport and no ID?
Wellif you get caught, and you dont cooperate with authorities in ascertaining exactly who you are, or authorities cant find out for whatever reason then you will wind up detained indefinitely. They wont let you go because you might be an escaped mass murderer, war criminal or some other shady character. They wont send you back to where you came from because no one else will take you either under those circumstances. There are several cases of people who actually did this, including a man who tried to enter Canada with a fake US passport. The man eventually told Canadian authorities he was actually from Cameroon and told then his name (or what he says was his name) ; the problem is Cameroon claimed he wasnt one of theirs, and that they had no record of him. In the meantime Canada tried to deport him to Guinea, Haiti and the USA where he came to Canada from but they refused to take him also. Basically Cameroon wouldnt cooperate with Canadian authorities ,because they apparently didnt want him back and Canada had to send an investigator there who actually found his birth record. He was then finally deported to Cameroon. He spent almost 10 years locked up in immigration detention in Canada.
