Canada, represented by the Canadian Olympic Committee (COC), competed at the 2008 Summer Olympics in Beijing, China, from August 8 to 24, 2008. Canadian athletes had competed in every Summer Olympic Games since 1900 with the exception of 1980, which were boycotted in protest of the Soviet invasion of Afghanistan. Canada sent 332 athletes in 25 sports, the seventh largest team at the games and Canada's largest since 1988. Canada did not send a team in handball, volleyball or basketball. Kayaker and 2004 Summer Olympics gold medalist Adam van Koeverden was the flag bearer at the opening ceremonies; Karen Cockburn bore the flag at the closing.
