Canada's official diplomatic position in relation to the Vietnam War was that of a non-belligerent, which imposed a ban on the export of war-related items to the combat areas. Nonetheless, Canadian industry was also a major supplier of equipment and supplies to the American forces, not sending these directly to South Vietnam but to the United States. Sold supplies included items like boots, but also munitions, napalm and commercial defoliants. Canadian industry sold $2.47 billion in materiel to the United States between 1965 and 1973. Canadian and American Defense departments worked together to test chemical defoliants for use in Vietnam and Canada also allowed the US to use Canadian facilities and bases for training exercises and weapons testing as per existing treaties. Between 28 January 1973 and 31 July 1973, Canada provided 240 peacekeeping troops to Operation Gallant, the peace keeping operation associated with the International Commission of Control and Supervision (ICCS) Vietnam, along with Hungary, Indonesia, and Poland. Their role was to monitor the cease-fire in South Vietnam per the Paris Peace Accords. About 30,000 Canadians volunteered to fight in southeast Asia. Among the volunteers were fifty Mohawks from the Kahnawake reserve near Montreal. One-hundred and ten Canadians died in Vietnam, and seven remain listed as Missing in Action. Canadian Vietnam veterans groups have held many events to have their participation in the Vietnam War. Canadian Peter C. Lemon was awarded the U.S. Medal of Honor for his valour in the conflict.
