This article is the Electoral history of Pierre Trudeau, the fifteenth Prime Minister of Canada. A Liberal, he served two terms as Prime Minister (1968–1979; 1980–1984). He led the Liberal Party in five general elections, winning four (1968, 1972, 1974 and 1980) and losing one (1979). He won majority governments in 1968, 1974 and 1980, and a minority government in the 1972 election. With a total of fifteen years and 164 days in office, he is the third longest serving prime minister, after William Lyon Mackenzie King and Sir John A. Macdonald. Trudeau succeeded Lester B. Pearson as prime minister in 1968. After Joe Clark won the 1979 election, Trudeau resigned and became Leader of the Opposition.
