city, Abitibi-Temiscamingue region, western Quebec province, Canada, on the western shore of Lake Osisko. It is located 315 miles (507 km) northwest of Montreal city. Rouyn and its twin city, Noranda, originated in the 1920s when gold and copper ores were first exploited in the area. Rouyn was named after the sieur de Rouyn, a hero of the Battle of Sainte-Foy (1760), and became the administrative, commercial, and industrial centre for the whole mining region of western Quebec. Noranda, noted for its big Noranda Mines Ltd. copper smelter, amalgamated with Rouyn in 1986. While copper and gold mining and refining remain the chief economic activities of Rouyn-Noranda, other industries include lumbering and dairying. Most of the population, about 80 percent, is French-Canadian, the remainder including some 30 different nationalities. The Canadian National Railway, two major highways, and an airport link the city with the rest of the continent. It is also the site of a college. Pop. (1991) 26,448.
