Ports (Great Lakes)
This page is brand new and is still being edited. I’ll add about 2 ports per week until done!
Over 40 million tonnes of cargo are shipped along the Great Lakes St. Lawrence Seaway. Commodities range from iron-ore to grains to finished goods.
About 2/3 of cargo is shipped downbound (toward the Atlantic Ocean) and the remaining 1/3 is upbound (toward the Great lakes). 60 percent of cargo originates in Canada, 25 percent in the U.S., and 15 percent is from the rest of the world.
