# Electoral history of Louis St. Laurent

This article is the electoral history of Louis St. Laurent, the twelfth prime minister of Canada (1948–1957).
A Liberal, St. Laurent served one term as prime minister (1948–1957), succeeding William Lyon Mackenzie King. He won two general elections (1948, 1953) and lost one (1957). John Diefenbaker succeeded him as prime minister, while Lester Pearson became the leader of the Liberal Party.
He stood for election to the House of Commons of Canada five times, all successfully.

## Summary

St. Laurent ranks ninth out of twenty-three prime ministers for time in office, serving one term of eight years and 218 days.
St. Laurent was the third of eight prime ministers from Quebec, the others being Sir John Abbott, Sir Wilfrid Laurier, Pierre Trudeau, Brian Mulroney, Jean Chrétien, Paul Martin and Justin Trudeau. He was also the second of five francophone prime ministers, the others being Laurier, Pierre Trudeau, Chrétien, and Justin Trudeau.
A late-comer to politics, St. Laurent was a well-respected lawyer when Prime Minister Mackenzie King recruited him to the federal government, to replace Ernest Lapointe, King's long-time Quebec lieutenant, who had died suddenly. St. Laurent served in King's government as Minister of Justice and Minister of External Affairs, as well as King's political Quebec lieutenant. When King retired after his lengthy time in office, he supported St. Laurent for the leadership of the Liberal Party. St. Laurent won on the first ballot and automatically became prime minister.
St. Laurent led the Liberal Party in two general elections in 1949 and 1953, winning majority governments each time. However, in his third general election, the major issue was the building of a trans-Canada gas pipeline, with financing from the federal government. The financing proposal triggered a controversial debate in the House of Commons, which St. Laurent's government ended by the use of closure to push the measure through the Commons. St. Laurent and the Liberals were defeated in the general election of 1957, with John Diefenbaker forming a minority government. St. Laurent stayed on as Liberal leader and Leader of the Opposition for half a year after the election. He resigned as Liberal leader early in 1958 and retired from politics. He was succeeded as Liberal leader by Lester B. Pearson.
St. Laurent stood for election to the Canadian House of Commons five times, all for the riding of Quebec East. He was elected each time (1942 (by-election), 1945, 1949, 1953 and 1957). He served in the Commons for a total of 16 years, 1 month, 20 days.
