Canada is a developed country whose economy includes the extraction and export of raw materials from its large area. Because of this, it has a transportation system which includes more than 1,400,000 kilometres (870,000 mi) of roads, 10 major international airports, 300 smaller airports, 72,093 km (44,797 mi) of functioning railway track, and more than 300 commercial ports and harbours that provide access to the Pacific, Atlantic and Arctic oceans as well as the Great Lakes and the Saint Lawrence Seaway.In 2005, the transportation sector made up 4.2% of Canada's GDP, compared to 3.7% for Canada's mining and oil and gas extraction industries.
Transport Canada oversees and regulates most aspects of transportation within Canadian jurisdiction. Transport Canada is under the direction of the federal government's Minister of Transport. The Transportation Safety Board of Canada is responsible for maintaining transportation safety in Canada by investigating accidents and making safety recommendations.
