Maritime commerce on the Great Lakes and St. Lawrence River is critical to the economies of the United States and Canada. The Martin Associates Economic Study seeks to measure and evaluate commerce and present a description of its economic impacts. Because of the geographic scope of the study area and the diverse stakeholders who might make use of this data, the study presents its results in numerous ways and from many perspectives.

How was this project developed?

This analysis estimates the combined U.S. and Canadian economic impacts of all marine cargo moving in the bi-national Great Lakes- St. Lawrence region, including domestic cargo moving between U.S. ports; domestic cargo moving between Canadian ports; cross-lake cargo moving between the U.S. and Canada; and international cargo moving between system ports and overseas ports.

The study measures the impacts of 2022 cargo movements at 40 U.S. and Canadian ports. The analysis was developed from a comprehensive telephone interview program of more than 800 individual firms with more than 1,100 operations throughout the region. Models were then developed to expand the 40-port impacts to the state-wide and province-wide levels.
