Canada in The Cold War - Canada-U.S. Tensions

Canada-U.S. Tensions

To defend North America against a possible enemy attack, Canada and the United States began to work very closely together in the 1950s. The North American Aerospace Defense Command (NORAD) created a joint air-defense system. In northern Canada, the Distant Early Warning Line (Dew Line) was established to give warning of Soviet bombers heading over the north pole. Great debate broke out while John Diefenbaker was Prime Minister as to whether Canada should accept U.S. nuclear weapons on its territory. Diefenbaker had already agreed to buy the BOMARC missile system from the Americans, which would be not as effective without nuclear warheads, but balked at permitting the weapons into Canada.

In the 1963 Canadian election, Diefenbaker was replaced by the famed diplomat Lester B. Pearson, who accepted the warheads. Further tensions developed when Pearson criticized the American role in the Vietnam War in a speech he gave at Temple University in Philadelphia, Pennsylvania. See also Canada and the Vietnam War.

Canada also maintained diplomatic and economic ties with Cuba following the Cuban Revolution.

Canada also refused to join the Organization of American States, disliking the support and tolerance of the Cold War OAS for dictators. Under Pearson’s successor Pierre Trudeau, US-Canadian policies grew further apart. Trudeau removed nuclear weapons from Canadian soil, formally recognized the People's Republic of China, established a personal friendship with Castro, and decreased the number of Canadian troops stationed at NATO bases in Europe.
