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
Cuba at the 2008 Summer Olympics by placing in the top two at the 2006 Americas Olympic Qualifying Event. The Cuba national baseball team has historically been very successful at the Olympics, winning the gold medal in three of the four tournaments held so far and taking the silver in 2000. Cuba qualified ten boxers for the Olympic boxing tournament. The light heavyweight class was the only one in which Cuba did not qualify a boxer. Nine of the ten Cuban qualifiers did so at the first American qualifying tournament. For the first time since the 1988 Olympic Games, Cuba did not win a gold medal.
