Happy International Left-Handers Day, Canada! You might be surprised to learn that lefties make up only about 10 per cent of the global population, but there are a few recognizable Canadians contributing to that number.

Here are some Canadian celebrities that are part of the southpaw club.

Céline Dion

The Quebec-born singer is actually a lefthander; she holds her microphone in her left hand when she performs on stage.

Happy #LeftHandersDay to left-handed legend Céline Dion! #DYK Dion's family is musical? Her mother was a violinist, her father an accordionist and many of her 13 older siblings were in show business. https://t.co/EjzD7WXkcL

Justin Bieber

The "One Less Lonely Girl" singer doesn't use his right hand; he signs autographs for fans southpaw-style.

Seth Rogen

The Canadian actor has been spotted signing autographs with his left hand and carrying a bag over his left shoulder, although he frequently uses his right hand to pick up objects on screen.

Keanu Reeves

The Toronto-raised actor is naturally left-handed, although he switched things up by playing bass with his bands Dogstar and Becky in a right-handed manner, per The Wrap.

James Cameron

The Ontario-born director of the Hollywood hit Titanic is actually left-handed. In fact, Cameron drew the famous sketch of a naked Rose wearing the Heart of the Ocean diamond, and the clip had to be altered to match the right-handed Leonardo DiCaprio, per Digital Spy.

Canadian hockey players Sidney Crosby and Wayne Gretzky are both technically right-handed off the ice, but both famous athletes are well-known for shooting left during games, making them honorary members of the southpaw club.

Keep proudly smudging those crosswords, lefties.
