Saint Lawrence Seaway

The Saint Lawrence Seaway (French: la Voie Maritime du Saint-Laurent) is the common name for a system of locks, canals and channels that permits ocean-going vessels to travel from the Atlantic Ocean to the Great Lakes, 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. This section upstream of the Seaway is not a continuous canal; rather, it consists of several stretches of navigable channels within the river, a number of locks, and canals along the banks of the St. Lawrence River to bypass several rapids and dams along the way. A number of the locks are managed by the Canadian Saint Lawrence Seaway Management Corporation, and others are managed by the American Saint Lawrence Seaway Development Corporation. The section of the river downstream of Montreal, which is fully within Canadian jurisdiction, is regulated by the offices of Transport Canada in the Port of Quebec.
