This article is the Electoral history of John Diefenbaker, the thirteenth Prime Minister of Canada. A Progressive Conservative, he served one term as Prime Minister (1957–1963), defeating Louis St. Laurent. He won three general elections (1957, 1958 and 1962), with one majority government and two minority governments. He lost the 1963 election to Lester Pearson, who succeeded him as prime minister. Diefenbaker led the party one last time in the 1965 election, but was again defeated by Pearson. He stood for election to the House of Commons of Canada fifteen times. He was defeated in his first two attempts (1925, 1926), but he was elected on his third try, in 1940. Thereafter, he was elected an additional twelve times, until he died in office in 1979. Diefenbaker sought the leadership of the Progressive Conservative Party three times, unsuccessfully in 1942 and 1948, before winning it in 1957. Following the loss in the election in 1965, the party held a leadership convention in 1967 which he lost, ending his leadership of the Progressive Conservative party. Robert Stanfield succeeded him as party leader. Prior to election to the House of Commons, Diefenbaker was also involved in Saskatchewan provincial politics and municipal politics, but with little success. Summary Diefenbaker ranks tenth out of twenty-three prime ministers for time in office, serving one term of five years and 305 days. Diefenbaker is the only prime minister from Saskatchewan. In 1920, Diefenbaker began his political career, starting with municipal politics. At age 25, he was elected to the village council of Wakaw, Saskatchewan, where he operated his first law practice. Diefenbaker would not win another election for twenty years. In the intervening two decades, he lost five elections: two at the federal level, two at the provincial level, and one at the municipal level. It was not until 1940 that he finally won his second election, to the House of Commons. From that point on, he never lost an election at the constituency level, winning thirteen straight elections to the Commons. Diefenbaker eventually died in office as a Member of Parliament. At the federal level, Diefenbaker stood for election in the general elections of 1925 and 1926, but was defeated both times. In the 1926 election, his Liberal opponent was the former prime minister, William Lyon Mackenzie King. This is the only time two future prime ministers have directly opposed each other in the same
