Structure of the Canadian federal government in the context of "Transport Canada"

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.

Parks Canada (French: Parcs Canada) is the agency of the Government of Canada which manages the country's 37 National Parks, three National Marine Conservation Areas, 172 National Historic Sites, one National Urban Park (Rouge), and one National Landmark (Pingo). It also manages 11 proposed national park areas (National Park Reserves). Parks Canada is mandated to "protect and present nationally significant examples of Canada's natural and cultural heritage, and foster public understanding, appreciation, and enjoyment in ways that ensure their ecological and commemorative integrity for present and future generations".

The agency also administers lands and waters set aside as potential national parklands, including ten National Park Reserves and one National Marine Conservation Area Reserve. More than 450,000 km (170,000 sq mi) of lands and waters in national parks and national marine conservation areas has been set aside for such purposes. Parks Canada cooperatively manages a large majority of their protected areas and heritage sites with Indigenous partners. The Canadian Register of Historic Places is supported and managed by the agency, in collaboration with provincial and territorial governments and other federal bodies. The agency is also the working arm of the national Historic Sites and Monuments Board, which recommends National Historic Sites, Events, and Persons.

Natural Resources Canada (NRCan; French: Ressources naturelles Canada; RNCan) is the department of the Government of Canada responsible for natural resources, energy, minerals and metals, forests, earth sciences, mapping, and remote sensing. It was formed in 1994 by amalgamating the Department of Energy, Mines and Resources with the Department of Forestry.

Under the Constitution Act, 1867, primary responsibility for natural resources falls to provincial governments, however, the federal government has jurisdiction over off-shore resources, trade and commerce in natural resources, statistics, international relations, and boundaries. The department administers federal legislation relating to natural resources, including energy, forests, minerals and metals. The department also collaborates with American and Mexican government scientists, along with the Commission for Environmental Cooperation, to produce the North American Environmental Atlas, which is used to depict and track environmental issues for a continental perspective.

The Canadian Food Inspection Agency (CFIA; French: Agence canadienne d'inspection des aliments (ACIA)) is a regulatory agency that is dedicated to the safeguarding of food, plants, and animals (FPA) in Canada, thus enhancing the health and well-being of Canada's people, environment and economy. The agency is responsible to the Minister of Health.

The agency was created in April 1997 by the Canadian Food Inspection Agency Act for the purpose of consolidating the delivery of all federal food safety, animal health, and plant health regulatory programs in Canada. As such, the CFIA was established by combining and integrating the related inspection services of three separate federal government departments:

Agriculture and Agri-Food Canada (AAFC; sometimes Ag-Canada; French: Agriculture et Agroalimentaire Canada) is the department of the Government of Canada responsible for the federal regulation of agriculture, including policies governing the production, processing, and marketing of all farm, food, and agri-based products. Agriculture in Canada is a shared jurisdiction and the department works with the provinces and territories in the development and delivery of policies and programs.

The minister of agriculture and agri-food is responsible for the department to Parliament. While the minister is head of the department, and provides policy/political direction, the day-to-day operations of the department are managed by the deputy minister, who is a public servant.
