An entertaining and theatrical speaker, John G. Diefenbaker was a Canadian populist who combined conservative politics with social justice issues. Of neither French nor English ancestry, Diefenbaker worked hard to include Canadians of other ethnic backgrounds. Diefenbaker gave western Canada a high profile, but Quebecers considered him unsympathetic.

John Diefenbaker had mixed success on the international front. He championed international human rights, but his confused defense policy and economic nationalism caused tension with the United States.

Birth and Death

Born on Sept. 18, 1895, in Neustadt, Ontario, to parents of German and Scottish descent, John George Diefenbaker moved with his family to Fort Carlton, Northwest Territories, in 1903 and Saskatoon, Saskatchewan, in 1910. He died on Aug. 16, 1979, in Ottawa, Ontario.


Diefenbaker received a bachelor's degree from the University of Saskatchewan in 1915 and a master's in political science and economics in 1916. After a brief enlistment in the army, Diefenbaker then returned to the University of Saskatchewan to study law, graduating with an LL.B. in 1919.

Highlights as Prime Minister

Diefenbaker was Canada's 13th prime minister, from 1957 to 1963. His term followed many years of Liberal Party control of the government. Among other accomplishments, Diefenbaker appointed Canada's first female federal Cabinet minister, Ellen Fairclough, in 1957. He prioritized extending the definition of "Canadian" to include not only those of French and English ancestry. Under his prime ministership, Canada's aboriginal peoples were allowed to vote federally for the first time, and the first native person was appointed to the Senate. He also found a market in China for prairie wheat, created the National Productivity Council in 1963, expanded old-age pensions, and introduced simultaneous translation in the House of Commons.
