The history of the petroleum industry in Canada arose in parallel with that of the United States. Because of Canada's unique geography, geology, resources and patterns of settlement, however, it developed in different ways. The evolution of the petroleum sector has been a key factor in the history of Canada, and helps illustrate how the country became quite distinct from her neighbour to the south.
Although the conventional oil and gas industry in western Canada is mature, the country's Arctic and offshore petroleum resources are mostly in early stages of exploration and development. Canada became a natural gas-producing giant in the late 1950s and is second, after Russia, in exports; the country also is home to the world's largest natural gas liquids extraction facilities. The industry started constructing its vast pipeline networks in the 1950s, thus beginning to develop domestic and international markets in a big way. Despite billions of dollars of investment, her bitumen - especially within the Athabasca oil sands - is still only a partially exploited resource. By 2025 this and other unconventional oil resources - the northern and offshore frontiers and heavy crude oil resources in the West - could place Canada in the top ranks among the world's oil producing and exporting nations. In a 2004 reassessment of global resources, America's EIA put Canadian oil reserves second; only Saudi Arabia has greater proved reserves.
