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
Puerto Rico at the 2008 Summer Olympics won six medals (one silver and five bronze). The last medal earned by a Puerto Rican was a bronze medal by Daniel Santos at the 1996 Summer Olympics in Atlanta. No medals were won by Puerto Ricans at Beijing. During the course of the 2008 Olympics, 22 athletes represented Puerto Rico—17 men and five women—in eight sports (track and field, boxing, artistic gymnastics, judo, shooting, swimming, taekwondo, and weightlifting). The size of the delegation was 21 athletes smaller than the Puerto Rican delegation that arrived at the 2004 Summer Olympics in Athens, and 58 athletes smaller than Puerto Rico's largest
