House of Commons of Canada in the context of "Government of Canada"

The Constitution Act, 1867 (French: Loi constitutionnelle de 1867), originally enacted as the British North America Act, 1867 (BNA Act), is a major part of the Constitution of Canada. The act created Canada, a federal country, and defines much of its structure, including the Parliament of Canada (composed of the monarch, the House of Commons, and the Senate), the executive, parts of the court system, and the division of powers between the federal government and the provinces. The act also created two new provinces, Ontario and Quebec, and set out their constitutions.

In 1982, with the patriation of the Constitution, the British North America Acts which were originally enacted by the British Parliament, including this act, were renamed the Constitution Acts. However, the acts are still known by their original names in records of the United Kingdom. Amendments were also made at this time: section 92A was added, giving provinces greater control over non-renewable natural resources.

The Parliament of Canada (French: Parlement du Canada) is the federal legislature of Canada. The Crown, along with two chambers: the Senate and the House of Commons, form the bicameral legislature.

The 343 members of the lower house, the House of Commons, are styled as Members of Parliament (MPs), and each elected to represent an electoral district (also known as a riding). The 105 members of the upper house, the Senate, are styled senators and appointed by the governor general on the advice of the prime minister. Collectively, MPs and senators are known as parliamentarians.

Before 1982, modifying the Constitution of Canada primarily meant amending the British North America Act, 1867. Unlike most other constitutions, however, the Act had no amending formula; instead, changes were enacted through Acts of the Parliament of the United Kingdom (or "Imperial Parliament") called the British North America Acts.

Other Commonwealth countries had taken over the authority for constitutional amendment after the Statute of Westminster 1931, but at the time, Canada decided to allow the Parliament of the United Kingdom to retain the power "temporarily". Between 1931 and 1982, the federal government, on behalf of the House of Commons of Canada and the Senate, would issue an address to the British government requesting an amendment. The request would include a resolution containing the desired amendments, which in turn were always passed by the British Parliament with little or no debate.

The Canada Act 1982 (1982 c. 11) (French: Loi de 1982 sur le Canada) is an act of the Parliament of the United Kingdom and one of the enactments which make up the Constitution of Canada. It was enacted at the request of the Senate and House of Commons of Canada to patriate Canada's constitution, ending the power of the British Parliament to amend the constitution. The act also formally ended the "request and consent" provisions of the Statute of Westminster 1931 in relation to Canada, whereby the British parliament had a general power to pass laws extending to Canada at its own request.

Annexed as Schedule B to the act is the text of the Constitution Act, 1982, in both of Canada's official languages (i.e. English and French). Because of the requirements of official bilingualism, the body of the Canada Act itself is also set out in French in Schedule A to the act, which is declared by s. 3 to have "the same authority in Canada as the English version thereof".

The Senate of Canada (French: Sénat du Canada) is the upper house of the Parliament of Canada. Together with the Crown and the House of Commons, they compose the bicameral legislature of Canada.

The Senate is modelled after the British House of Lords, with its members appointed by the governor general on the advice of the prime minister. The appointment is made primarily by four divisions, each having twenty-four senators: the Maritime division, the Quebec division, the Ontario division, and the Western division. Newfoundland and Labrador is not part of any division, and has six senators. Each of the three territories has one senator, bringing the total to 105 senators. Senate appointments were originally for life; since 1965, they have been subject to a mandatory retirement age of 75.

A member of Parliament (post-nominal letters: MP; French: député, [depyte]) is an elected politician in the House of Commons of Canada, the lower house of the Parliament of Canada.

An electoral district in Canada is a geographical constituency upon which Canada's representative democracy is based. It is officially known in Canadian French as a circonscription but frequently called a comté ('county'). In Canadian English it is also colloquially, and more commonly known as a riding or constituency.

Each federal electoral district returns one Member of Parliament (MP) to the House of Commons of Canada; each provincial or territorial electoral district returns one representative—called, depending on the province or territory, Member of the Legislative Assembly (MLA), Member of the National Assembly (MNA), Member of Provincial Parliament (MPP) or Member of the House of Assembly (MHA)—to the provincial or territorial legislature.

The prime minister of Canada is the head of government of Canada. Under the Westminster system, the prime minister governs with the confidence of a majority of the elected House of Commons; as such, the prime minister typically sits as a member of Parliament (MP) and leads the largest party or a coalition of parties. As first minister, the prime minister selects ministers to form the Cabinet.

Not outlined in any constitutional document, the prime minister is appointed by the monarch's representative, the governor general, and the office exists per long-established convention. Constitutionally, executive authority is vested in the monarch (who is the head of state), but the powers of the monarch and governor general are nearly always exercised on the advice of the Cabinet, which is collectively responsible to the House of Commons. Canadian prime ministers are appointed to the Privy Council and styled as the Right Honourable (French: le très honorable), a privilege maintained for life.
