# Electoral history of Lester B. Pearson

This article is the Electoral history of Lester B. Pearson, the fourteenth Prime Minister of Canada.
A Liberal, he served one term as prime minister (1963–1968). He led the Liberal Party in four general elections, losing two (1958 and 1962) to John Diefenbaker, and winning two (1963 and 1965), defeating Diefenbaker both times. Both victories resulted in hung parliaments and he formed two minority governments. He retired in 1968 and was succeeded by Pierre Trudeau.
Pearson stood for election to the House of Commons of Canada eight times, all for the riding of Algoma East in northern Ontario. He was elected each time.

## Summary

Pearson ranks twelfth out of twenty-three prime ministers for time in office, serving one term of four years and 364 days.
Pearson was the fifth of five prime ministers from Ontario, the others being Sir John A. Macdonald, Alexander Mackenzie, Sir Mackenzie Bowell, and William Lyon Mackenzie King.
Before entering politics, Pearson was a career diplomat in the Department of External Affairs, including being the Canadian Ambassador to the United States. Prime Minister Mackenzie King invited Pearson several times to join King's government, an invitation Pearson finally accepted in 1948, at the end of King's time in office. King appointed him Minister of External Affairs and Pearson entered Parliament shortly afterwards by a by-election in the northern Ontario riding of Algoma East.
Pearson served in the government of Louis St. Laurent as Minister of External Affairs from 1948 to 1957. Following the defeat of the Liberals in the 1957 general election, Pearson succeeded St. Laurent as leader of the Liberal Party of Canada, becoming Leader of the Opposition in 1958. He was unsuccessful in the first two general elections he contested as leader (1958, 1962), with Diefenbaker continuing in office, but in the general election of 1963 he won a minority government, defeating Diefenbaker. Pearson was returned to office in the 1965 election, again defeating Diefenbaker, again with a minority government.
Pearson stood for election to the House of Commons eight times and was elected in all eight elections (1948 (by-election), 1949, 1953, 1957, 1958, 1962, 1963 and 1965). Throughout his parliamentary career, he represented the riding of Algoma East in northern Ontario. He won each election by a majority of more than 50% of the votes, even in multi-candidate elections. He served in the Commons for 19 years, 7 months, and 30 days.
In 1968, Pearson announced his retirement and was succeeded as Liberal leader and prime minister by Pierre Trudeau.

## Federal general elections: 1958 to 1965

### Federal election, 1958

After winning the Liberal leadership, Pearson challenged the legitimacy of Diefenbaker's minority government. In response, Diefenbaker called a snap election.
