Founded as Skea’s Corners on the military Kingston Road in 1795, it was renamed Oshawa—an Indigenous word referring to a stream crossing—in 1842, when a post office was established there. The city, which is now a port of entry and a major manufacturing center, is the home site of General Motors of Canada. There are also woolen mills, foundries, and plants that manufacture machine parts, fabricated metals, glass, plastics, pharmaceuticals, furniture, leather, and electrical appliances. Inc. village, 1850; town, 1879; city, 1924. Pop. (2011) 149,607; (2021) 175,383.
