common law and the
civil law; accepts compulsory
International Court of Justice jurisdiction, with reservations. Common law is used in all provinces and territories except Quebec, which is a civil law jurisdiction, using the
Civil Code of Quebec.

Monarchy Head of state ,
of Canada (since ).
Governor General Mary Simon,
Governor General of Canada (since July 26, 2021). Canada is a constitutional monarchy, wherein the role of the reigning
sovereign is both legal and practical, but not political. The
monarch is formally vested with all powers of state, which are in practice exercised only by the various institutions of government acting under the sovereign's authority. The executive is thus formally referred to as the
King-in-Council, the legislature as the
King-in-Parliament, and the courts as the
King-on-the-Bench. Though the person who is monarch of Canada (currently ) is also the monarch of
14 other countries in the
Commonwealth of Nations, he nevertheless reigns separately as
of Canada, an office that is "truly Canadian" and "totally independent from that of the
monarch of the United Kingdom or the other Commonwealth realms." On the advice of the Canadian prime minister, the sovereign appoints a federal
viceregal representative—the
governor general (currently
Mary Simon)—who, since 1947, is permitted to exercise almost all of the monarch's
royal prerogative; though, there are some duties which must be specifically performed by the monarch themselves (such as assent of certain bills). In case of the governor general's absence or incapacitation, the
administrator of Canada performs the Crown's most basic functions.
Royal assent is required to enact laws. As part of the royal prerogative, the
royal sign-manual gives authority to
letters patent and
orders-in-Council. The royal prerogative also includes summoning,
proroguing, and
dissolving Parliament in order to
call an election and extends to foreign affairs, which include the negotiation and ratification of treaties, alliances, international agreements, and
declarations of war; the accreditation of Canadian diplomats and receipt of foreign diplomats; and the
issuance of passports. Despite the wide theoretical extent of the sovereign's powers, in actual practice the sovereign exercises them only through or with the advice of the Prime Minister and
Cabinet. Within the
constitutional conventions of the
Westminster system, the sovereign's freedom of action or personal choice in any area of governance is quite limited.
Executive power from 1867 to 1963. The
Prime Minister of Canada serves as the
head of government.
Head of government Mark Carney,
Prime Minister of Canada (since March 14, 2025).
Cabinet Ministers (usually around thirty) chosen by the prime minister and appointed by the governor general to lead various ministries and agencies, generally with regional representation. Traditionally most, if not all, cabinet ministers will be members of the leader's own party in the House of Commons or Senate (see
Cabinet of Canada); however this is not legally or constitutionally mandated, and occasionally, the prime minister will appoint a cabinet minister from another party.
Elections The monarchy is hereditary. The governor general is appointed by the monarch on the advice of the Prime Minister for a non-specific term, though it is traditionally approximately five years. Following legislative elections, the leader of the majority party in the House of Commons is usually designated by the governor general to become prime minister.
Legislative power The
bicameral Parliament of Canada consists of three parts: the
monarch, the
Senate, and the
House of Commons. The Senate, which is frequently described as providing regional representation, has 105 members appointed by the Governor-General on the advice of the Prime Minister to serve until age 75. It was created with equal representation from the three regions of Ontario, Quebec, and the Maritimes (originally New Brunswick and Nova Scotia, expanded in 1873 to include Prince Edward Island). In 1915, a new Western division was created, with six senators from each of the four western provinces, so that each of the four regions had 24 seats in the Senate. When Newfoundland and Labrador joined Confederation in 1949, it was not included in an existing region and was assigned six seats. Each of the three territories has one seat. It is not based on representation-by-population. The normal number of senators can be exceeded by the Governor General at the direction of the monarch on the advice of the Prime Minister, as long as the additional senators are distributed equally with regard to region (up to a total of eight additional senators). This power of additional appointment has only been used once, when Prime Minister
Brian Mulroney petitioned
Queen Elizabeth II to direct that eight seats be added to the Senate so as to ensure the passage of the
Goods and Services Tax legislation. is one of three components of the
Parliament of Canada. The House of Commons currently has 343 members elected in
single-member districts in a
plurality voting system (first past the post), meaning that members must attain only a
plurality (the most votes of any candidate) rather than a
majority. The
electoral districts are also known as
ridings. Mandates cannot exceed five years; an election must occur by the end of this time. This fixed mandate has been exceeded only once, when Prime Minister
Robert Borden perceived the need to do so during World War I. A
constitutional amendment was passed, extending the life of the Parliament by one year, by the unanimous consent of the House of Commons. The size of the House and
apportionment of seats to each province is revised after every decennial census, conducted every ten years, and is based on population changes and approximately on representation-by-population.
Elections and government formation Canadians vote for the election of their local
member of parliament (MP) only. A vote is cast directly for a candidate. Most candidates affiliate themselves to a
political party, but candidates can run as
independents. The candidate in each riding who receives a plurality of votes (single member plurality or so-called
first-past-the-post system) is elected, whether or not they receive a majority of district votes. An MP need not be a member of any political party. MPs may sit as
independents. The
Canada Elections Act defines a political party as "an organization one of whose fundamental purposes is to participate in public affairs by endorsing one or more of its members as candidates and supporting their election." Forming and registering a federal political party are two different things. There is no legislation regulating the formation of federal political parties.
Elections Canada cannot dictate how a federal political party should be formed or how its legal, internal and financial structures should operate. Most parties elect their leaders in
instant-runoff elections to ensure that the winner receives more than 50% of the votes. This happens at
leadership conventions. Normally the party leader stands as a candidate to be an MP during an election. Canada's parliamentary system empowers political parties and their party leaders. Where one party gets a majority of the seats in the House of Commons, that party is said to have a "majority government" and by itself has right to form the cabinet and pass laws. Through party discipline, the party leader, who if elected sits in only one riding, exercises control over the cabinet and the parliament. Historically, the
prime minister and senators are selected by the
governor general as a representative of the , though in modern practice the monarch's duties are ceremonial. Consequently, the prime minister, while technically selected by the Governor General, is for all practical purposes selected by the party with the majority of seats (or the party that can get support from a majority of MPs). That is, the party that gets the most seats normally forms the government, with that party's leader becoming prime minister. The prime minister is not directly elected by the general population, although the prime minister is almost always elected as an MP within a single riding. Often elections give one party a majority of the seats in the House of Commons, even if the party did not receive a majority of the vote. However, as there are usually three or more political parties represented in the House of Commons, often no party takes a majority of the seats. A
minority government occurs when no party in the House of Commons holds more seats than the opposition parties combined. However, for the new government to survive and to pass laws, the leader chosen must have the support of the majority of the House, meaning they need the support of the elected members of at least one other party. This can be done on a case-by-case basis, through a coalition government (which has only occurred once at the federal level, the
Unionist government formed during the First World War) or through a
confidence-and-supply agreement (such as the one the Liberals and the NDP signed in 2022). If a party in power does not get support of a majority of MPs in a vote in the House of Commons, the defeated ministry may choose to stay in office until defeated on a vote of confidence in the House, or it may resign. If it resigns, the governor general may call an election immediately or may ask the leader of an opposition party to form a government. And again that new governing party has to aggregate support of a majority of MPs in the House of Commons, if it is to hold its position as governing party. ==Federal-provincial relations==
