Corner Brook, city on the west coast of Newfoundland, Newfoundland and Labrador, Canada. It lies at the mouth of the Humber River (there called Humber Arm in the Bay of Islands), 427 miles (687 km) northwest of St. John’s. The site of the province’s first industrial sawmill (1894), it developed after construction there of one of the world’s largest pulp and paper mills (1925), powered by a hydroelectric plant at Deer Lake. Corner Brook, the second largest city in the province (after St. John’s), is now the centre of a lumbering, salmon-fishing, limestone-quarrying, and mink-farming region. In addition to pulp and newsprint production, there are cement and gypsum plants, iron foundries, and furniture factories. A planned town, incorporated in 1955 and named for a local brook, it became a city in 1956 when it amalgamated with the adjacent communities of Town Site, Corner Brook East and West, Curling, and Humbermouth. The Sir Wilfred Grenfell College (1975) at Corner Brook is affiliated with Memorial University of Newfoundland at St. John’s. Pop. (2006) 20,083; (2011) 19,886.
