Petrolia is a town in Ontario twenty minutes from Sarnia, and fifty minutes from London.Following the discovery of oil at Oil Springs in 1857, prospectors extended their search to the entire township of Enniskillen. At the site of Petrolia, which contained two small settlements with post offices named Durance and Ennis, a well was brought into production in 1860. The following year a small refinery was opened and the Durance Post Office renamed "Petrolea". In 1865-66, the drilling of the King well established Petrolia as the major oil producing center in Canada and its population soared from about three hundred to two thousand three hundred. Oil men from Petrolia travelled to the far reaches of the world (Gobi Desert, Arctic, Iran, Indonesia, the United States, Australia, Russia, and over eighty other countries) teaching others how to find and extract crude oil. Some oil fields in the area are still operational to this day.Oil enticed people to come here, but Petrolia was created, nurtured, and sustained by hardworking visionaries, shopkeepers, builders, drillers, laborers, and leaders.
