The St. Lawrence Seaway opened to navigation in 1959.

Construction of the 189-mile (306-kilometer) stretch of the Seaway between Montreal and Lake Ontario is recognized as one of the most challenging engineering feats in history, according to the Great Lakes St. Lawrence Seaway System website at www.greatlakes-seaway.com.

Seven locks were built in the Montreal-Lake Ontario section of the Seaway, five Canadian and two U.S., in order to lift vessels to 246 feet (75 meters) above sea level, the website said.

The 28-mile (44 kilometer) Welland Canal is the fourth version of a waterway link between Lake Ontario and Lake Erie, first built in 1829.

The present canal was competed in 1932, deepened in the 1950s as part of the Seaway project, and further straightened in 1973. Today its eight locks, all Canadian, lift ships 326 feet (100 meters) over the Niagara Escarpment, said the website.

A 2018 analysis by the Saint Lawrence Seaway Development Corporation found that commercial navigation that transits the St. Lawrence River and Lake Ontario sustains 92,661 jobs (32,855 U.S. and 59,806 Canadian) and almost $13 billion in economic activity, according to the corporation’s quarterly newsletter.

If the amount of overall economic activity supported by Seaway navigation, $13 billion, is divided by the average length of the Seaway’s navigation season, 280 days, the average daily economic activity number supported by the Seaway would be calculated at $46.4 million per day, the analysis said.
