Minister of the Crown in the context of "Chancellor of the Exchequer"

The Government of Canada (French: gouvernement du Canada), formally His Majesty's Government (French: Gouvernement de Sa Majesté), is the body responsible for the federal administration of Canada. The term Government of Canada refers specifically to the executive, which includes ministers of the Crown (together in the Cabinet) and the federal civil service (whom the Cabinet direct); it is corporately branded as the Government of Canada. There are over 100 departments and agencies, as well as over 300,000 persons employed in the Government of Canada. These institutions carry out the programs and enforce the laws established by the Parliament of Canada.

The federal government's organization and structure was established at Confederation, through the Constitution Act, 1867, wherein the Canadian Crown acts as the core, or "the most basic building block", of its Westminster-style parliamentary democracy. The monarch, King Charles III is head of state and is personally represented by a governor general (currently Mary Simon). The prime minister (currently Mark Carney) is the head of government, who is invited by the Crown to form a government after securing the confidence of the House of Commons, which is typically determined through the election of enough members of a single political party in a federal election to provide a majority of seats in Parliament, forming a governing party. Further elements of governance are outlined in the rest of the Canadian constitution, which includes written statutes in addition to court rulings and unwritten conventions developed over centuries.

The prime minister of the United Kingdom is the head of government of the United Kingdom. The prime minister advises the sovereign on the exercise of much of the royal prerogative, chairs the Cabinet, and selects its ministers. Modern prime ministers hold office by virtue of their ability to command the confidence of the House of Commons, so they are invariably members of Parliament.

The office of prime minister is not established by any statute or constitutional document, but exists only by long-established convention, whereby the monarch appoints as prime minister the person most likely to command the confidence of the House of Commons. In practice, this is the leader of the political party that holds the largest number of seats in the Commons. The prime minister is ex officio also First Lord of the Treasury (an office often associated with the premiership between 1721 and 1895, after 1902 always united to it, and, after 1905, an official title of the position), Minister for the Civil Service, the minister responsible for national security, and Minister for the Union. The prime minister's official residence and office is 10 Downing Street in London.

His Majesty's Government, abbreviated to HM Government or otherwise UK Government, is the central executive authority of the United Kingdom of Great Britain and Northern Ireland. The government is led by the prime minister (Keir Starmer since 5 July 2024) who selects all the other ministers. The government is currently supported by the Labour party, which has had a majority in the House of Commons since 2024. The prime minister and his most senior ministers belong to the supreme decision-making committee, known as the Cabinet.

Ministers of the Crown are responsible to the House in which they sit; they make statements in that House and take questions from members of that House. For most senior ministers this is usually the elected House of Commons rather than the House of Lords. The government is dependent on Parliament to make primary legislation, and general elections are held at least once every five years to elect a new House of Commons, unless the prime minister advises the monarch to dissolve Parliament, in which case an election may be held sooner. After an election, the monarch selects as prime minister the leader of the party most likely to command the confidence of the House of Commons, usually by possessing a majority of MPs.

The lord chancellor, formally titled Lord High Chancellor of Great Britain, is a senior minister of the Crown within the Government of the United Kingdom. The lord chancellor is the minister of justice for England and Wales and the highest-ranking Great Officer of State in Scotland and England, nominally outranking the prime minister. The lord chancellor is appointed and dismissed by the sovereign on the advice of the prime minister. Prior to the union of England and Scotland into the Kingdom of Great Britain, there were separate lord chancellors for the Kingdom of England (including Wales) and the Kingdom of Scotland. Likewise, the Lordship of Ireland and its successor states (the Kingdom of Ireland and United Kingdom of Great Britain and Ireland) maintained the office of lord chancellor of Ireland until the establishment of the Irish Free State in 1922, whereupon the office was abolished.

The lord chancellor is a member of the Cabinet and is, by law, the minister of the Crown responsible for the efficient functioning and independence of the courts. The lord chancellor thus leads the Ministry of Justice and is the judiciary's voice within Cabinet. In 2005, there were a number of changes to the legal system and to the office of the lord chancellor. Previously, the lord chancellor was also the presiding officer of the House of Lords, the head of the judiciary of England and Wales and the presiding judge of the Chancery Division of the High Court of Justice. The Constitutional Reform Act 2005 transferred these roles to the lord speaker, the lord chief justice and the chancellor of the High Court respectively.

Deputy minister is a title borne by politicians or officials in certain countries governed under a parliamentary system. A deputy minister is positioned in some way "under" a minister, who is a full member of Cabinet, in charge of a particular standing policy portfolio, and typically oversees an associated civil service department. Depending on the jurisdiction, a "Deputy minister" may be a Cabinet minister who regularly acts as and for a more senior cabinet minister (rare except in the case of "Deputy Prime Minister"), a junior minister assigned to assist a cabinet minister, an elected member of the governing party or coalition assigned to assist a specific cabinet minister "from the back benches" (i.e., not part of the Cabinet, Government or Ministry) or a non-elected head of a civil service department taking political direction from a Cabinet minister.

• Bangladesh: A Deputy minister is junior to a Minister of a Department of State (portfolio minister) and of similar standing to a Parliamentary Secretary.
• Canada: The Deputy minister is the senior civil servant in a government department and takes political direction from an appointed minister of the Crown.
• Japan: A Deputy Minister assists the work of the Cabinet of Japan.
• Malaysia: A Deputy minister is not a member of the Cabinet and also called half minister. It is secondary to and ranked below ministers. Deputy ministers deputise for ministers. A ministry usually has one or two deputy ministers.
• Netherlands: A State Secretary is the title of a junior member of the Cabinet of the Netherlands.
• Poland: The ministries are staffed by secretaries of state and undersecretaries of state, commonly referred to as deputy ministers. Their task is to assist the Minister and replace him if necessary. Main article: Secretary of state (Poland) [pl]
• South Africa: A Deputy Minister is secondary to cabinet ministers. The Official Opposition Shadow Cabinet also has deputy shadow ministers.
• Sri Lanka: A Deputy ministers are junior ministers ranking below that of cabinet minister and State Minister. It is similar to the pre-1972 post of Parliamentary Secretary.
• Tanzania: The Deputy ministers are junior ministers, and are usually not members of the government's cabinet.
• Timor-Leste: The Government, which comprises the Prime Minister, Ministers and Secretaries of State, may include one or more Deputy Prime Ministers and Deputy Ministers.

The Canadian Ministry (French: Conseil des ministres), colloquially referred to as the Cabinet of Canada (French: Cabinet du Canada), is a body of ministers of the Crown that, along with the Canadian monarch, and within the tenets of the Westminster system, forms the government of Canada. Chaired by the prime minister, the Cabinet is part of and acts on behalf of the King's Privy Council for Canada and the senior echelon of the Ministry, the membership of the Cabinet and Ministry often being co-terminal; as of March 2025 there were no members of the latter who were not also members of the former.

For practical reasons, the Cabinet is informally referred to either in relation to the prime minister in charge of it or the number of ministries since Confederation. The current Cabinet is the Cabinet of Mark Carney, which is part of the 30th Ministry. The interchangeable use of the terms cabinet and ministry is a subtle inaccuracy that can cause confusion.
