Great Lakes-St. Lawrence Seaway Tonnage Reports

A new system-wide report from the Chamber of Marine Commerce shows that Great Lakes-St. Lawrence Seaway ships carried an estimated 149 million metric tons of cargo to and from domestic ports as well as to overseas markets during the 2021 shipping season — an increase of 7% over pandemic-stricken 2020.

“This report paints a clear picture that the bi-national Great Lakes-St. Lawrence Seaway System supported the economic recovery and growth of many of our key industries in both Canada and the U.S. The navigation system delivered critical raw materials and products without any of the delay or disruption seen in other global markets,” said Bruce R. Burrows, President and CEO of the Chamber of Marine Commerce. “In today’s high-inflation business environment, it’s more important than ever that we focus our attention and investment on this unique inland marine highway as part of the solution to many of our national transportation and supply chain problems.”

The 2021 Great Lakes-St. Lawrence Seaway System Tonnage Activity report, the only data resource of its kind that annually collects and analyzes Canadian-flag, U.S.-flag and foreign-flag tonnage for the bi-national navigation system, provides an overview of the key cargo commodities and their underlying economic and business drivers.
