When I went to Quebec and had to go to hospital for an x-ray (ankle wasn't broken! yay!) they asked my parents names for the paperwork, and were super confused that they had the same last name. I didn't speak very good french and the receptionist didn't speak very good english, so it took a bit of back and forth for them to get my mom's maiden name out of me. So I have a health certificate card from Quebec that says my mom's name is something it hasn't been since 1989. I'm still mad that Sophie Grégoire Trudeau had to change her name when her husband went into politics.
