Got any favourite Canadian celebrities?

Michael J Fox is my absolute favorite actor of all time: Back to the Future, Family Ties, etc. I also like Shania Twain. She is probably my second favorite country artist, behind Taylor Swift, although I've been listening to Shania more recently. I didn't actually know Dan Ackroyd and Jim Carrey were Canadian, but they are funny too. Justin Bieber of course is great, lol, only kinda, but better than me.
