Petro Canada has one of the more unique corporate histories. After the oil crisis of the 1970s, the Canadian government decided to found it as a crown corporation in 1975 to exploit oil resources in Alberta. The resulting company proved successful, eventually expanding into extraction operations across the country. The government began privatizing Petro Canada in 1991, eventually selling its entire stake, with the result being that the independent company was the purchased by Suncor in 2009. Canadian consumers, however, largely know it through the iconic maple leaf logo which adorns the more than 1,500 locations that provide fuel and convenience products across the country. The brand is also extremely active in sports promotion, having sponsored more than 3,000 Olympic and Paralympic athletes and their families since 1988.
