National Parks of Canada

Canada’s national parks are protected areas established under federal legislation to preserve Canada’s natural heritage. They are administered by Parks Canada, a government agency that evolved from the world’s first national parks service, the Dominion Parks Branch, established in 1911. The National Parks System Plan, developed in 1970, divided Canada into 39 natural regions and set the goal of representing each region with at least one national park. Canada now has 48 national parks and national park reserves in 30 of these regions. In total, the parks cover more than 340,000 km2, which is over 3 per cent of Canada’s landmass. They protect important land and marine habitats, geographical features and sites of cultural significance. National parks also benefit local economies and the tourism industry in Canada.
