Korean War

The Korean War began 25 June 1950, when North Korean armed forces invaded South Korea. The war’s combat phase lasted until an armistice was signed 27 July 1953. As part of a United Nations (UN) force, 26,791 Canadian military personnel served in the Korean War, during both the combat phase and as peacekeepers afterward. After the two world wars, Korea remains Canada’s third-bloodiest overseas conflict, taking the lives of 516 Canadians and wounding more than 1,200.
