# Electoral history of William Lyon Mackenzie King

This article is the electoral history of William Lyon Mackenzie King, the tenth Prime Minister of Canada. A Liberal, he was Canada's longest-serving prime minister, with three separate terms as prime minister (1921–1926, 1926–1930 and 1935–1948), for a total of 21 years and 154 days. He defeated Prime Ministers Arthur Meighen and R.B. Bennett at different times, and was succeeded by Prime Minister Louis St. Laurent in 1948.
King was elected to the House of Commons of Canada twelve times (1908, 1909, 1919, 1921, 1922, 1926 (twice), 1930, 1935, 1940, and 1945).
He was elected leader of the Liberal Party of Canada in 1919, by the first leadership convention for a federal party in Canada.

## Summary

King was the longest-serving Prime Minister, in office for a total of 21 years, 154 days. He led the Liberal Party of Canada in seven consecutive general elections, winning six times (1921, 1925, 1926, 1935, 1940, 1945) and losing once (1930). He won minority governments three times (1925, 1926 1945) and majority governments three times (1921, 1935, and 1940). He is in a three-way tie with Sir John A. Macdonald and Sir Wilfrid Laurier for the number of general elections he contested as leader of a party.
His unbroken term in office from October 23, 1935 to November 14, 1948 (just over thirteen years) is the second-longest unbroken term, coming after Laurier's unbroken term in office of over fifteen years (July 11, 1896 to October 6, 1911) and just ahead of Macdonald's longest unbroken term of just under thirteen years (October 17, 1878 to June 6, 1891).
King was the third of four prime ministers to serve non-consecutive terms, the others being Macdonald, Meighen, and Pierre Trudeau.
King was the fourth of five prime ministers from Ontario, the others being Sir John A. Macdonald, Alexander Mackenzie, Sir Mackenzie Bowell, and Lester Pearson.
King stood for election to the House of Commons of Canada sixteen times, in ten general elections and six by-elections. He was elected twelve times and defeated four times. Three of the by-elections were ministerial by-elections, triggered by King entering the federal Cabinet, once as Minister of Labour (1909) and twice as prime minister (1922, 1926). Two of the by-elections were in response to his defeats in his own constituency in general elections, which compelled him to seek election to a safe seat to re-enter the Commons. One by-election was after his election as leader of the Liberal Party, where he stood for election in a vacant seat to enter the House of Commons as quickly as possible.
King was a member of the House of Commons for five different constituencies, from three different provinces (Ontario, Prince Edward Island and Saskatchewan), a more diverse electoral record than any other prime minister. He served in the House of Commons for a total of 32 years and 7 days.

## Federal general elections, 1921 to 1945

King led the Liberal Party in seven general elections, winning six (three majority governments and three minority governments) and was defeated once.

### Canadian federal election, 1921

The 1921 election resulted in the a razor-thin majority government for King. King was able to maintain his government for four years, with the support of the Progressives in the Commons.

### Canadian federal election, 1925

Although Arthur Meighen and the Liberal-Conservatives won more seats than King and the Liberals, King was able to form a minority government with the support of the Progressives. King was also defeated in his own seat of York North, Ontario and had to seek election in a safe seat, Prince Albert, Saskatchewan. However, he was forced to resign over a federal procurement scandal less than a year into office, leading to his replacement as prime minister by Arthur Meighen, leader of the Liberal-Conservatives. These events triggered a constitutional crisis, the King–Byng Affair, and the general election of 1926.

### Canadian federal election, 1926

This general election was called on the advice of Prime Minister Meighen, appointed prime minister by the Governor-General, Viscount Byng, after King resigned as prime minister. King's resignation triggered a constitutional crisis, the King–Byng Affair. King and the Liberals won the greatest number of seats in the election, but were short of a majority. King formed a minority government with support from some Progressives, particularly the Liberal-Progressives. His minority government lasted for four years.
