Fifty years after the official opening of the St. Lawrence Seaway by Her Majesty Queen Elizabeth II and President Dwight D. Eisenhower, the Canadian and U.S. Seaway corporations remain resolute in their commitment to the sustainability of this bi-national transportation system. A recent U.S. and Canadian Government study concluded that the use of the Great Lakes and St. Lawrence Seaway (GLSLS) saves consumers $3.6 billion per year in shipping costs. In addition, over 150,000 jobs on both sides of the border are dependent on GLSLS shipping.
