Canada at the Summer Olympics became the first Canadian Summer Olympian to win a medal in four straight Olympics. After George Hodgson won two gold medals in the 1912 Stockholm games, it would be 72 years before Alex Baumann became the second Canadian swimmer to win Olympic gold, when he won both individual medley events in world record time in the 1984 Los Angeles games. Victor Davis (1984), Anne Ottenbrite (1984), Mark Tewksbury (1992) and Penny Oleksiak (2016) are the only other Canadian swimmers to win gold medals. In 2004, Canada failed to win a medal of any colour in swimming for the first time
