Parks Canada, the world's first national park service, is established as the Dominion Parks Branch under the Department of the Interior.
A national park is a natural park in use for conservation purposes, created and protected by national governments. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride.The United States established the first "public park or pleasuring-ground for the benefit and enjoyment of the people", Yellowstone National Park, in 1872. Although Yellowstone was not officially termed a "national park" in its establishing law, it was always termed such in practice and is widely held to be the first and oldest national park in the world. However, the Tobago Main Ridge Forest Reserve (in what is now Trinidad and Tobago; established in 1776), and the area surrounding Bogd Khan Uul Mountain (Mongolia, 1778), which were restricted from cultivation in order to protect surrounding farmland, are seen as the oldest legally protected areas.An international organization, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas (WCPA), has defined "National Park" as its Category II type of protected areas. According to the IUCN, 6,555 national parks worldwide met its criteria in 2006. IUCN is still discussing the parameters of defining a national park.National parks are almost always open to visitors.
Parks Canada (PC; French: Parcs Canada), is the agency of the Government of Canada which manages the country's 38 National Parks, three National Marine Conservation Areas, 172 National Historic Sites, one National Urban Park, and one National Landmark. 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 10 National Park Reserves and one National Marine Conservation Area Reserve. More than 450,000 km2 (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.
The minister of environment and climate change (Steven Guilbeault since 2021) is responsible for the agency, and it is managed by its chief executive officer (Ron Hallman since 2019). The agency's budget was $1.3 billion in the 2020–2021 fiscal year and it employed 4,666 public servants in March 2021.
