Saint Lawrence Seaway The Saint Lawrence Seaway (French: "la Voie Maritime du Saint-Laurent" ) is a system of locks, canals and channels in Canada and the United States that permit ocean-going vessels to travel from the Atlantic Ocean to the Great Lakes of North America, as far inland as the western end of Lake Superior. The Seaway is named for the Saint Lawrence River, which flows from Lake Ontario to the Atlantic Ocean. Legally, the Seaway extends from Montreal, Quebec, to Lake Erie and includes the Welland Canal.
