Bush Flying in Canada

In Canada, bush flying refers to aviation in sparsely populated northern areas. Flight in the Arctic and the “bush” of the Canadian Shield developed between the world wars. Early bush pilots faced the challenges of cold weather and vast distances between communities. Given the rarity of airstrips, their planes were often equipped with skis or floats so that they could take off and land on water or snow. This type of aviation was key to developing services and industries in the North. While the romantic image of the bush pilot is associated with the past, bush flying continues to serve remote communities in Canada.

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.
