I’m not too sure about that. That’s a generalisation on far positive side. If you read reviews for land border landings for some of the borders you will see there are “alleged” rude agents. So much so some refusing to process PR card unless you’re settling for good. So at the end its up to an individual agent. Plus there have been ample example of rude agents on call. So yeah Canadians can be rude because they are also people.That's what we want to think. Even when Canadians are rude, they're still nice I would say.
