Canada in the Cold War
In 1945, Canada emerged from the Second World War as a world power with over one million service personnel. The nation transformed from an agricultural dominion into a sovereign state focused on resource extraction and high-technology research. Its military grew to become the fifth largest surface fleet and fourth largest air force globally. Despite drawing down forces after the war, the Canadian military executed Operation Muskox across the Arctic region. This massive deployment trained troops for potential ground and air warfare in the north. Canadians also sent observers to India and Palestine in 1947 and 1948 for United Nations humanitarian efforts.
February 1946 marked a turning point when the Canadian government disclosed Igor Gouzenko's defection from the Soviet Union. Gouzenko was a cipher clerk who revealed a spy ring operating within Ottawa. Historians use this event to mark the beginning of the Cold War era in Canada. The affair triggered another red scare that intensified domestic anti-communist sentiment. The Communist Party of Canada had not been outlawed since Section 98 was repealed by Prime Minister William Lyon Mackenzie King in 1935. The government implemented PROFUNC, a top secret plan to identify and detain communist sympathizers during the height of the Cold War. Surveillance continued despite a comparatively moderate stance compared to American policies.
Canada became a founding member of NATO in 1949 with Prime Minister Louis St. Laurent as a chief architect. The nation maintained military bases in Germany including CFB Baden-Soellingen and CFB Lahr in the Black Forest region. Facilities also existed in Bermuda, France, and the United Kingdom. From the early 1960s until the 1980s, Canada hosted weapon platforms armed with nuclear weapons. These included nuclear-tipped air-to-air rockets, surface-to-air missiles, and high-yield gravity bombs deployed in Western Europe and Canada. The North American Aerospace Defence Command formed in 1958 created a joint air-defense system. Northern radar systems like the Distant Early Warning Line warned of Soviet bombers heading over the north pole.
The Korean War saw Canadian volunteer soldiers make noteworthy contributions to United Nations forces. The Princess Patricia's Canadian Light Infantry served with distinction at the Battle of Kapyong. During the Suez Crisis of 1956, diplomat Lester B. Pearson re-introduced the concept of a UN military force. His Emergency Force separated combatants and enforced a ceasefire between Britain, France, Israel, and Egypt. This was the first peacekeeping force ever deployed globally. Canada provided the greatest amount of UN peacekeepers during the Cold War from 1948 until 1989. Subsequent interventions occurred in the Congo in 1960, Cyprus in 1964, and Vietnam through the International Control Commission.
John Diefenbaker became Prime Minister in 1957 amid debates about accepting US nuclear weapons on Canadian soil. He agreed to buy the BOMARC missile system but balked at permitting warheads into Canada. During the Cuban Missile Crisis in 1962, Diefenbaker refused to put armed forces on immediate war alert status. A tense phone call between President John F. Kennedy and Diefenbaker eventually led to preparations for enemy attack. The crisis left the governing party in disarray over nuclear arms questions. In 1963, Lester B. Pearson replaced Diefenbaker and accepted the warheads despite opposition.
The Nixon shock economic policies of 1971 prompted Canada to articulate a Third Option policy. This plan aimed to diversify trade and downgrade the importance of relations with the United States. Richard Nixon declared the special relationship dead during an Ottawa speech in 1972. Pierre Trudeau removed nuclear weapons from Canadian soil and formally recognized the People's Republic of China. He established personal friendships with Cuban leader Fidel Castro while decreasing troops at NATO bases in Europe. Alexander Yakovlev served as Soviet ambassador to Canada from the mid-1970s for a decade. He and Trudeau became close friends discussing liberalization needs within the Soviet Union.
A 1987 White Paper on Defence signaled intent to reassert sovereignty over Arctic waters. Project Spinnaker monitored submarine traffic by deploying acoustic listening posts on the seafloor. The project required developing Theseus, an autonomous underwater vehicle designed to lay communications cables under permanent ice cover. In spring 1996, Theseus was transported to CFS Alert on Ellesmere Island. It laid 180 kilometers of fiber optic cable on the seafloor in ice-covered waters. By 1994, the last active US military base in Canada, Naval Station Argentia Newfoundland, decommissioned. The facility stored Mk 101 Lulu and B57 nuclear bombs before becoming part of the SOSUS network.
