The 
St. Lawrence Seaway (
French: 
la Voie Maritime du Saint-Laurent) is a system of 
locks, 
canals, and channels in Canada and the United States that permits oceangoing vessels to travel from the Atlantic Ocean to the 
Great Lakes of North America, as far inland as 
Duluth, Minnesota, at the western end of 
Lake Superior. The seaway is named for the 
St. 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. Ships from the Atlantic Ocean are able to reach ports in all five of the Great Lakes.
