The St. Lawrence Seaway celebrates its 50th anniversary at the St. Lambert Lock, Quebec.
Inaugurated in 1959 by Queen Elizabeth II and President Eisenhower, the Seaway stands as evidence of an enduring asset. Since its inception, over 2.5 billion tonnes of cargo has been transported.
The Great Lakes/St. Lawrence Seaway was built as a binational partnership between the U.S. and Canada, and continues to operate as such. Administration is shared by two entities, the Saint Lawrence Seaway Development Corp. in the U.S., a federal agency within the U.S. Department of Transportation, and The St. Lawrence Seaway Management Corporation in Canada, a not-for-profit corporation (ownership of the Canadian portion of the Seaway remains with the Canadian federal government.)
The Great Lakes St. Lawrence Seaway System is a deep draft waterway extending 3,700 km from the Atlantic Ocean to the head of the Great Lakes, in the heart of North America. The St. Lawrence Seaway portion of the System extends from Montreal to mid-Lake Erie. It includes 13 Canadian and 2 U.S. locks.
