• On June 26, 1959, the St. Lawrence Seaway officially opened. The St. Lawrence Seaway allowed ports on the Great Lakes to trade with ships from the Atlantic Ocean.
    The St. Lawrence Seaway is not a single route, but a series of canals. Some ports on the seaway include Montreal, Quebec, Canada, on the St. Lawrence River; Toronto, Ontario, Canada, on Lake Ontario; Chicago, Illinois, on Lake Michigan; and Duluth, Minnesota, on Lake Superior.
    More than 40 million tons of cargo pass through the St. Lawrence Seaway every year. About half of that traffic is from Europe, Africa, and the Middle East. The other half is trade between U.S. and Canadian ports.
