The St. Lawrence River is a large river in the middle latitudes of North America, flowing from Lake Ontario in a roughly northeasterly direction into the Gulf of St. Lawrence, connecting the Great Lakes to the North Atlantic Ocean and forming the primary drainage outflow of the Great Lakes Basin. The river traverses the Canadian provinces of Ontario and Quebec as well as the U.S. state of New York, and is part of the international boundary between Canada and the United States. It also provides the basis for the commercial St. Lawrence Seaway.
