The prime minister of Canada (French: premier ministre du Canada)[note 1] is the first minister of the Crown. The prime minister acts as the head of government for Canada, chairs and selects the membership of the Cabinet, and advises the Crown on the exercise of executive power and much of the royal prerogative. As prime ministers hold office by virtue of their ability to command the confidence of the elected House of Commons, they typically sit as a member of Parliament (MP) and lead the largest party or a coalition in the House of Commons.
Justin Trudeau is the 23rd and current prime minister of Canada. He took office on November 4, 2015, following the 2015 federal election where his Liberal Party won a majority of seats and was invited to form the 29th Canadian Ministry. Trudeau was subsequently re-elected following the 2019 and 2021 elections with a minority of seats.
Not outlined in any constitutional document, the office exists only per long-established convention (originating in Canada's former colonial power, the United Kingdom) that stipulates the monarch's representative, the governor general, must select as prime minister the person most likely to command the confidence of the elected House of Commons; this individual is typically the leader of the political party that holds the largest number of seats in that chamber.[note 2] Canadian prime ministers are appointed to the Privy Council and styled as the Right Honourable (French: Le très honorable),[note 3] a privilege maintained for life.
The prime minister is supported by the Prime Minister's Office and heads the Privy Council Office. The prime minister also effectively appoints individuals to the Senate of Canada and to the Supreme Court of Canada and other federal courts, along with choosing the leaders and boards, as required under law, of various Crown corporations. Under the Constitution Act, 1867, government power is vested in the monarch (who is the head of state), but in practice the role of the monarch—or their representative, the governor general (or the administrator)—is largely ceremonial and only exercised on the advice of a Cabinet minister. The prime minister also provides advice to the monarch of Canada for the selection of the governor general.
The position of prime minister is not outlined in any Canadian constitutional document and is mentioned only in passing in the Constitution Act, 1982, and the Letters Patent, 1947 issued by King George VI. The office and its functions are instead governed by constitutional conventions and modelled on the same office in the United Kingdom.
The prime minister, along with the other ministers in Cabinet, is appointed by the governor general on behalf of the monarch. However, by the conventions of responsible government, designed to maintain administrative stability, the governor general will call to form a government the individual most likely to receive the support, or confidence, of a majority of the directly elected members of the House of Commons; as a practical matter, this is often the leader of a party whose members form a majority, or a very large plurality, of the House of Commons.
While there is no legal requirement for prime ministers to be MPs themselves, for practical and political reasons the prime minister is expected to win a seat very promptly. However, in rare circumstances individuals who are not sitting members of the House of Commons have been appointed to the position of prime minister. Two former prime ministers—John Joseph Caldwell Abbott and Mackenzie Bowell—served in the 1890s while members of the Senate. Both, in their roles as Government Leader in the Senate, succeeded prime ministers who had died in office—John A. Macdonald in 1891 and John Sparrow David Thompson in 1894. That convention has since evolved toward the appointment of an interim leader from the commons in such a scenario.
Prime ministers who are not MPs upon their appointment (or who lose their seats while in office) have since been expected to seek election to the House of Commons as soon as possible. For example, William Lyon Mackenzie King, after losing his seat in the 1925 federal election (that his party won), briefly "governed from the hallway" before winning a by-election a few weeks later. Similarly, John Turner replaced Pierre Trudeau as leader of the Liberal Party in 1984 and subsequently was appointed prime minister while not holding a seat in the House of Commons; Turner won a riding in the next election but the Liberal Party was swept from power. Turner was the last prime minister to not occupy a House of Commons seat while in office as prime minister.
Should a serving prime minister today lose his or her seat in the legislature, or should a new prime minister be appointed without holding a seat, the typical process that follows is that a junior member in the governing political party will resign to allow the prime minister to run in the resulting by-election. A safe seat is usually chosen; while the Liberal and Conservative parties traditionally observed a convention of not running a candidate against another party's new leader in the by-election, the New Democratic Party and smaller political parties typically do not follow the same convention. However, if the governing party selects a new leader shortly before an election is due, and that new leader is not a member of the legislature, he or she will normally await the upcoming election before running for a seat in Parliament.

The prime minister serves At Her Majesty's pleasure, meaning, the post does not have a fixed term, and that once appointed and sworn in by the governor general, the prime minister remains in office until they resign, are dismissed, or die. In practice, under the system of responsible government, the prime minister (by convention) resigns should they lose the confidence of the elected House of Commons. This can happen if the government loses an important vote, such as on the budget (loss of supply), or more explicitly if a motion of no confidence is passed. A loss of confidence is rare if the government enjoys a majority. Majority governments typically last about four years (since elections are normally held every four years). Minority governments are more liable to lose the confidence of the House of Commons and generally last for a shorter period of time.
While the lifespan of a parliament is constitutionally limited to five years, a 2007 amendment to the Canada Elections Act, Section 56.1(2) limited the term of a majority government to four years, with election day being set as the third Monday in October of the fourth calendar year after the previous polling date The governor general may still, on the advice of the prime minister, dissolve parliament and issue the writs of election prior to the date mandated by the constitution or Canada Elections Act; the King–Byng Affair was the only time since Confederation that the governor general deemed it necessary to refuse his prime minister's request for a general vote.
Following parliamentary dissolution, the prime minister must run in the resulting general election if he or she wishes to maintain a seat in the House of Commons. Should the prime minister's party subsequently win a majority of seats in the House of Commons, it is unnecessary to re-appoint the prime minister or again swear him or her into office. If, however, an opposition party wins a majority of seats, the prime minister may resign or be dismissed by the governor general. Should the prime minister's party achieve a minority while an opposition party wins a plurality (i.e., more seats than any other party but less than a majority), the prime minister can attempt to maintain the confidence of the House by forming a coalition with other minority parties, which was last entertained in 1925 or by entering into a confidence-and-supply agreement.
Two official residences are provided to the prime minister—24 Sussex Drive in Ottawa and Harrington Lake, a country retreat in Gatineau Park—as well an office in the Office of the Prime Minister and Privy Council building (formerly known as Langevin Block), across from Parliament Hill. For transportation, the prime minister is afforded an armoured car (a car allowance of $2,000) and shared use of two official aircraft—a CC-150 Polaris for international flights and a Challenger 601 for domestic trips. The Royal Canadian Mounted Police also furnish constant personal security for the prime minister and their family. All of the aforementioned is provided through budgets approved by Parliament, as is the prime minister's total annual compensation of CA$357,800 (consisting of an MP's salary of CA$178,900 and the prime minister's salary of CA$178,900).
Should a serving or former prime minister die, he or she is accorded a state funeral, wherein their casket lies in state in the Centre Block of Parliament Hill. Only Bowell and the Viscount Bennett were given private funerals, Bennett also being the only former prime minister of Canada to die and be buried outside the country and Bowell the only whose funeral was not attended by politicians. John Thompson also died outside Canada, at Windsor Castle, where Queen Victoria permitted his lying-in-state before his body was returned to Canada for a state funeral in Halifax.
In earlier years, it was traditional for the monarch to bestow a knighthood on newly appointed Canadian prime ministers. Accordingly, several carried the prefix Sir before their name; of the first eight premiers of Canada, only Alexander Mackenzie refused the honour of a knighthood from Queen Victoria. Following the 1919 Nickle Resolution, however, the House of Commons motioned that it should be against the policy of the Canadian Sovereign (and Her Canadian Majesty's government advising the Monarch when such honours are not within the Monarch's personal gift) to bestow aristocratic or chivalric titles to Canadians. The Crown in right of Canada (but not the Crown in right of the United Kingdom, which has periodically bestowed such Imperial honours on such citizens) has since adopted this policy generally, such that the last prime minister to be knighted near appointment was Robert Borden, who was the prime minister at the time the Nickle Resolution was debated in the House of Commons (and was knighted before the resolution). Still, Bennett was, in 1941, six years after he stepped down as prime minister, elevated to the peerage of the United Kingdom by King George VI as Viscount Bennett, of Mickleham in the County of Surrey and of Calgary and Hopewell in Canada. No prime minister has since been titled.
The Canadian Heraldic Authority (CHA) has granted former prime ministers an augmentation of honour on the personal coat of arms of those who pursued them. The heraldic badge, referred to by the CHA as the mark of the Prime Ministership of Canada, consists of four red maple leaves joined at the stem on a white field ("Argent four maple leaves conjoined in cross at the stem Gules"); the augmentation has, so far, been granted either as a canton sinister or centred in the chief. To date, former prime ministers Joe Clark, Pierre Trudeau, John Turner, Brian Mulroney, Kim Campbell and Jean Chrétien were granted arms with the augmentation.
Canada continues the Westminster tradition of using the title Prime Minister when one is speaking to the federal head of government directly; the Department of Canadian Heritage advises that it is incorrect to use the term Mr. Prime Minister. The written form of address for the prime minister should use his or her full parliamentary title: The Right Honourable [name], [post-nominal letters], Prime Minister of Canada. However, while in the House of Commons during Question Period, other members of parliament may address the prime minister as the Right Honourable Member for [prime minister's riding] or simply the Right Honourable Prime Minister. Former prime ministers retain the prefix the Right Honourable for the remainder of their lives; should they remain sitting MPs, they may be referred as the Right Honourable Member for [member's riding], by their portfolio title (if appointed to one), as in the Right Honourable Minister of National Defence, or should they become opposition leader, as the Right Honourable Leader of the Opposition.
In the decades following Confederation, it was common practice to refer to the prime minister as Premier of Canada, a custom that continued until the First World War, around the time of Robert Borden's premiership. While contemporary sources will still speak of early prime ministers of Canada as premier, the modern practice is such that the federal head of government is known almost exclusively as the prime minister, while the provincial and territorial heads of government are termed premiers (in French, premiers are addressed as premier ministre du [province], literally translated as prime minister of [province]).

The prime minister–designate of Canada refers to the person who has been designated as the future prime minister by the governor general, after either winning a general election, forming a confidence and supply government, or forming a coalition government. The term does not apply to incumbent prime ministers.
After exiting office, former prime ministers of Canada have engaged in various pursuits. Some remained in politics: Bowell continued to serve as a senator, Stephen Harper returned to the House of Commons as a backbench MP, and Bennett moved to the United Kingdom after being elevated to the House of Lords. A number served as leaders of the Official Opposition: John A. Macdonald, Arthur Meighen, Mackenzie King, and Pierre Trudeau, all before being re-appointed as prime minister (Mackenzie King twice); Alexander Mackenzie and John Diefenbaker, both prior to sitting as regular Members of Parliament until their deaths; Wilfrid Laurier dying while still in the post; and Charles Tupper, Louis St. Laurent, and John Turner, each before they returned to private business. Meighen was also appointed to the Senate following his second period as prime minister, but resigned his seat to seek re-election and moved to private enterprise after failing to win a riding. Also returning to civilian life were: Robert Borden, who served as Chancellor of Queen's and McGill Universities, as well as working in the financial sector; Lester B. Pearson, who acted as Chancellor of Carleton University; Joe Clark and Kim Campbell, who became university professors, Clark also consultant and Campbell working in international diplomacy and as the director of private companies and chairperson of interest groups; while Pierre Trudeau and Jean Chrétien returned to legal practice. Former prime ministers also commonly penned autobiographies—Tupper, for example—or published their memoirs—such as Diefenbaker and Paul Martin.
