The Saint Lawrence River (in French: fleuve Saint-Laurent; Kahnawáˀkye in Tuscarora, Kaniatarowanenneh meaning big waterway in Mohawk) is a large river flowing approximately from southwest to northeast in the middle latitudes of North America, connecting the Great Lakes with the Atlantic Ocean. It is the primary drainage of the Great Lakes Basin. It traverses the Canadian provinces of Quebec and Ontario and forms part of the international boundary between Ontario and other places in the U.S.A.
The Saint Lawrence River originates at the outflow of Lake Ontario between Kingston, Ontario on the north bank, Wolfe Island in mid-stream, and Cape Vincent, New York.
From there, it passes Gananoque, Brockville, Ogdensburg, Massena, Cornwall, Montreal, Trois-Rivières, and Quebec City before draining into the Gulf of Saint Lawrence, the largest estuary in the world. The river runs 3,058 km (1,900 mi) from the furthest headwater to the mouth and 1,197 km (743.8 mi) from the outflow of Lake Ontario. The furthest headwater is the North River in the Mesabi Range at Hibbing, Minnesota. Its drainage area, which includes the Great Lakes and hence the world's largest system of fresh water lakes, has a size of 1,030,000 km2 (397,685 sq mi). The average discharge at the mouth is 10,400 m3/s (367,273 cu ft/s). The river includes Lake Saint-Louis south of Montreal, Lac Saint-François at Salaberry-de-Valleyfield and Lac Saint-Pierre east of Montreal. It encompasses three archipelagoes: the Thousand Islands chain near Kingston, Ontario; the Hochelaga Archipelago, including the Island of Montreal and Île Jésus (Laval); and the smaller Mingan Archipelago. Other islands include Île d'Orléans near Quebec City, and Anticosti Island north of the Gaspé.it is the 2nd longest river in Canada.
