Did Canada build the st Lawrence seaway?

Answer 1

The St Lawrence Seaway (Great Lakes Waterway) is the system of locks, canals and channels linking the GREAT LAKES and the ST LAWRENCE RIVER with the Atlantic Ocean. The construction of progressively larger canals along the St Lawrence River began as early as 1783. By 1900, a complete network of shallow draft canals allowed uninterrupted navigation from Lake SUPERIOR to MONTRÉAL.

Between 1913 and 1932, the WELLAND CANAL, between Lakes ERIE and ONTARIO, was rebuilt, but the US was reluctant to enter a larger scheme, that is, to rebuild the Montréal-Lake Ontario channels. A threat by the Canadian government in 1951 to build a seaway entirely within Canadian territory resulted in a final agreement in 1954. Construction on the St Lawrence Seaway and Power Project began on 10 August 1954. In addition to the building of 7 locks and deepening navigation channels to a depth of 8.2 m, the project also included the construction of the 2090 megawatt Moses-Saunders Powerhouse near CORNWALL, Ont. The Seaway was opened to commercial traffic 25 April 1959 with the official opening 26 June 1959, attended by Prime Minister John Diefenbaker, President Dwight D. Eisenhower and Queen Elizabeth II.
