context_page_description: Transportation in Canada, the world's second-largest country in total area, is dedicated to having an efficient, high-capacity multimodal transport spanning often vast distances between natural resource extraction sites, agricultural and urban areas. Canada's transportation system includes more than 1,400,000 kilometres of roads, 10 major international airports, 300 smaller airports, 72,093 km 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 St. 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 federal jurisdiction, including interprovincial transport. This primarily includes rail, air and maritime transportation. 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.
context_section_description: There is a total of 1,042,300 km (647,700 mi) of roads in Canada, of which 415,600 km (258,200 mi) are paved, including 17,000 km (11,000 mi) of expressways (the third-longest collection in the world, behind the Interstate Highway System of the United States and the China's National Trunk Highway System). As of 2008, 626,700 km (389,400 mi) were unpaved.
  In 2009, there were 20,706,616 road vehicles registered in Canada, of which 96% were vehicles under 4.5 tonnes (4.4 long tons; 5.0 short tons), 2.4% were vehicles between 4.5 and 15 tonnes (4.4 and 14.8 long tons; 5.0 and 16.5 short tons) and 1.6% were 15 tonnes (15 long tons; 17 short tons) or greater. These vehicles travelled a total of 333.29 billion kilometres, of which 303.6 billion was for vehicles under 4.5 tonnes, 8.3 billion was for vehicles between 4.5 and 15 tonnes and 21.4 billion was for vehicles over 15 tonnes. For the 4.5- to 15-tonne trucks, 88.9% of vehicle-kilometres were intra-province trips, 4.9% were inter-province, 2.8% were between Canada and the US and 3.4% made outside of Canada. For the trucks over 15 tonnes, 59.1% of vehicle-kilometres were intra-province trips, 20% inter-province trips, 13.8% Canada-US trips and 7.1% trips made outside of Canada.
  Canada's vehicles consumed a total of 31.4 million cubic metres (198 Mbbl) of gasoline and 9.91 million cubic metres (62.3 Mbbl) of diesel. Trucking generated 35% of the total GDP from transport, compared to 25% for rail, water and air combined (the remainder being generated by the industry's transit, pipeline, scenic and support activities). Hence roads are the dominant means of passenger and freight transport in Canada.
  Roads and highways were managed by provincial and municipal authorities until construction of the Northwest Highway System (the Alaska Highway) and the Trans-Canada Highway project initiation. The Alaska Highway of 1942 was constructed during World War II for military purposes connecting Fort St. John, British Columbia with Fairbanks, Alaska. The transcontinental highway, a joint national and provincial expenditure, was begun in 1949 under the initiation of the Trans Canada Highway Act on December 10, 1949. The 7,821-kilometre (4,860 mi) highway was completed in 1962 at a total expenditure of $1.4 billion.
  Internationally, Canada has road links with both the lower 48 US states and Alaska. The Ministry of Transportation maintains the road network in Ontario and also employs Ministry of Transport Enforcement Officers for the purpose of administering the Canada Transportation Act and related regulations. The Department of Transportation in New Brunswick performs a similar task in that province as well.
  Regulations enacted in regards to Canada highways are the 1971 Motor Vehicle Safety Act and the 1990 Highway Traffic Act
  The safety of Canada's roads is moderately good by international standards, and is improving both in terms of accidents per head of population and per billion vehicle kilometers.
