List of prime ministers of Canada

The Prime Minister of Canada is the official who serves as the main minister of the Crown, chair of the Cabinet, and head of government of Canada. 24 people (23 men and 1 woman) have been prime minister, serving 29 distinct terms. Officially, the prime minister is appointed by the Governor General of Canada, but the prime minister must have the confidence of the elected House of Commons. Normally, this is the leader of the party with the greatest number of seats in the house.

A prime minister holds a seat in parliament and, since the early 20th century, this has more specifically meant the House of Commons.

Prime ministers

In Canada, they count the individuals who were prime minister, not by terms.

LSParty won the election, but prime minister lost own seat *The Interpretation Act of 1967 states that "where an appointment is made effective or terminates on a specified day, that appointment is considered to be effective or to terminate after the end of the previous day." Under the Act, prime ministers' tenures are therefore credited as having concluded at the end of their last full day in office, although their resignation was received by the governor general on the following day. This provision applies to P. Trudeau in 1979 and 1984, Clark, Turner, Mulroney, Campbell, Chrétien, Martin, Harper, and J. Trudeau.
