CHATEAUGUAY

town, Montrgie region, southern Quebec province, Canada. It lies at the mouth of the Chteauguay River, just south of its confluence with the St. Lawrence. The site of a Jesuit mission established in 1736, it served as a trading centre during the settlement of the surrounding region. On Oct. 26, 1813, the Battle of Chteauguay, a decisive engagement of the War of 1812, took place there; a small party of British troops under Colonel Charles de Salaberry repelled an attacking U.S. force, preventing their attempted capture of Montreal. Now a dairying and fruit-growing centre, Chteauguay has developed into a residential suburb 12 miles (19 km) southwest of Montreal city. The town's manufactures include road conduits and doors. Pop. (1991) 39,833.
