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
Great Britain at the 2012 Summer Olympics medal with Anna Watkins in the women's double sculls, became the first Great Britain female athlete to win four Olympic medals, and at four successive games (having previously won three silver medals). Swimmer Rebecca Adlington equalled the feat of four Olympic medals later on the same day. Sophie Hosking and Katherine Copeland, in the women's lightweight double sculls, completed the hat-trick as part of Super Saturday. Despite the unprecedented success, Great Britain performed much more poorly in the team sports, winning just a single medal when Great Britain captained by Katie Walsh won the bronze medal match against New Zealand
