The St. Lawrence Seaway is a series of locks, canals and channels that links the Atlantic Ocean and St. Lawrence River to Lake Ontario and the four Upper Great Lakes. It extends from Montreal to Lake Erie and it includes the Welland Canal. This is an important water route, which was opened to navigation in 1959.

The St. Lawrence seaway provides direct access to export and import markets by ocean-going vessels, many of which are equipped with self-unloading devices for unloading at shore facilities (ship to land) or transshipping bulk cargo (ship to ship).

It is part of an excellent intermodal transportation network that is strategically located geographically and directly serves Ontario and Quebec to the north, and Illinois, Michigan, Ohio, Indiana, Wisconsin, Minnesota, New York and Pennsylvania to the south.

The St. Lawrence Seaway is managed and operated by The St. Lawrence Seaway Management Corporation of Canada and the United States Saint Lawrence Seaway Development Corporation.
