Have you ever heard of?

So, had a conversation with my MIL over coffee this morning that ended with her saying, "Maybe its just a Canadian thing." Is it common in Canada to take your boyfriend's last name if he wont marry you? Do you know anyone who has done this? They are common law with 3 children, but wedding plans have been off more than they have been on. It kind of struck me as controlling and a bit stalkerish, but she seemed surprised I felt that way, so I'm curious.
