What are Cabinet committees?

Cabinet committees are sub-groups of the federal Cabinet that handle specific policy areas, prepare Cabinet decisions, and reduce the workload of full Cabinet meetings. The structure and membership of Cabinet committees is set by the Prime Minister, who appoints the chair and members of each committee. Cabinet committees operate under terms of reference prepared by the Privy Council Office and meet regularly during sittings of Parliament. Most policy proposals are discussed in Cabinet committee before going to full Cabinet for approval.

Under Prime Minister Mark Carney's 2025 Cabinet, the principal Cabinet committees include Treasury Board (the only statutorily required committee, established under the Financial Administration Act); Priorities and Strategy (chaired by the Prime Minister, sets overall direction); Operations (chaired by the Deputy Prime Minister, manages day-to-day government); Economic Growth and Affordability; Climate, Energy and the Environment; Foreign Affairs and Defence; Indigenous Reconciliation and Self-Determination; Health; Social Innovation; Public Safety; and the Cabinet Committee on Canadian Sovereignty (created 2025 to manage Canada-US tensions). Specific committee structures change with each Prime Minister's preferences.

Cabinet committees provide three main benefits. First, specialisation: ministers with expertise or strong interest in a topic concentrate on it, while other ministers focus on their own portfolios. Second, deliberation: smaller groups can debate proposals more thoroughly than a full Cabinet of 30 to 40 ministers. Third, efficiency: routine decisions are made at committee level (with Cabinet ratifying summary decisions), freeing full Cabinet for the most important or politically sensitive items. Cabinet committee meetings are private, with deliberations protected by Cabinet confidence.

Each Cabinet committee is supported by a Privy Council Office secretariat that prepares background materials, drafts minutes, and tracks implementation. The PCO's Cabinet Affairs branch coordinates the overall Cabinet process. Federal departments propose Memoranda to Cabinet (MCs) through their portfolio Cabinet committee, which can recommend approval (with or without modifications), defer for further work, or reject. Approved proposals go to full Cabinet for final approval, after which the decision is implemented through Orders in Council, departmental action, or new legislation. Notable historical Cabinet committees have included the 1968 to 1979 Trudeau Cabinet's collegial committee system, Brian Mulroney's expanded committee structure, and Stephen Harper's smaller, more centralised committee system.
