The following list outlines the structure of the federal government of Canada, the collective set of federal institutions which can be grouped into the legislative, executive, and judicial branches. In turn, these are further divided into departments, agencies, and other organizations which support the day-to-day function of the Canadian state. The list includes roughly 130 departments and other organizations, with nearly 300,000 employees, who collectively form the Public Service of Canada. Special Operating Agencies (which are departmental organizations), and non-departmental organizations such as Crown corporations, administrative tribunals, and oversight organizations are parts of the public service operating in areas seen as requiring a higher level of independence from it and the direct political control of ministers. Public servants are agents of the Crown and responsible to Parliament through their relevant minister. This list is organized according to functional grouping and is further subdivided by category such as offices, departments, agencies, and Crown corporations: The Crown Regal and vice-regal offices King of Canada Canadian Secretary to the King Governor General of Canada Secretary to the Governor General of Canada Canadian Heraldic Authority King's Privy Council King's Privy Council for Canada Cabinet of Canada Treasury Board of Canada Canada School of Public Service Treasury Board Secretariat Privy Council Office Intergovernmental Affairs Secretariat Office of the Leader of the Government in the House of Commons Executive Public Service Central agencies Ministerial departments Separate agency with direct ministerial oversight Independent agencies and offices Canadian Judicial Council National Judicial Institute National Security and Intelligence Review Agency Office of the Commissioner for Federal Judicial Affairs Office of the Chief Military Judge Public Service Commission of Canada Transportation Safety Board Independent review bodies Federal Public Sector Labour Relations and Employment Board Public Servants Disclosure Protection Tribunal Canadian Human Rights Commission Canadian Human Rights Tribunal Canadian Armed Forces Parliament Senate of Canada Procedural officers Speaker of the Senate Clerk of the Senate and Clerk of the Parliaments Usher of the Black Rod of the Senate of Canada Standing committees Aboriginal Peoples Agriculture and Forestry Banking, Trade, and Commerce Ethics and Conflict of Interest for Senators Energy, the Environment and Natural Resources Fisheries and Oceans Foreign Affairs and International Trade Human Rights Internal Economy, Budgets, and Administration Diversity subcommittee Human Resources subcommittee Senate Estimates subcommittee Legal and Constitutional Affairs National Finance National Security and Defence Official Languages Rules, Procedure and the Rights of Parliament Selection Committee Social Affairs, Science
