Date	1990s
Location	Great Lakes, St. Lawrence River
Participants	Canada, United States
Outcome	Multinational recommendations on waterway infrastructure, navigation, and environmental management

Great Lakes–St. Lawrence Transportation Study The Great Lakes–St. Lawrence Transportation Study was a binational assessment undertaken by Canadian and American agencies to evaluate navigation, infrastructure, and environmental management across the Great Lakes and St. Lawrence River. The study coordinated input from federal departments, provincial and state authorities, and multinational stakeholders including shipping interests and indigenous nations such as the Anishinaabe and Haudenosaunee. Its timing intersected with policy debates involving the International Joint Commission, the St. Lawrence Seaway Authority, and the United States Army Corps of Engineers.

Background and Objectives

The study emerged amid competing priorities among actors including the Government of Canada, the United States Department of Transportation, the Ministry of Transport (Canada), and the Great Lakes Commission to reconcile commercial navigation with conservation commitments under instruments like the Boundary Waters Treaty of 1909. Objectives included assessing links between port capacity at Montreal, dredging needs near Chicago, lock modernization at Sault Ste. Marie, and intermodal connections to corridors such as the Saint Lawrence Seaway and the Interstate Highway System. Stakeholders from the Canadian Coast Guard, Transport Canada, the National Oceanic and Atmospheric Administration, and regional bodies such as the Council of Great Lakes Governors contributed to framing goals involving trade facilitation, hazard mitigation near the Niagara River, and cross-border emergency response coordination with entities like the Federal Emergency Management Agency.

Study Methodology and Scope

Analytical teams drew expertise from agencies including the United States Geological Survey, the Ontario Ministry of Natural Resources and Forestry, academic institutions like the University of Toronto and the Great Lakes Research Center, and private consultants with ties to firms such as Dillon Consulting. The study used hydrodynamic modeling informed by data from the International Hydrographic Organization, bathymetry surveys near the Straits of Mackinac, and traffic statistics from terminal operators at Port of Toronto, Port of Detroit, and Port of Montreal. Scenario analysis examined bulk cargo flows tied to commodities traded through the Port of Duluth–Superior and container movements affecting terminals at Hamilton, Ontario and Milwaukee, Wisconsin. Environmental scope included invasive species vectors such as zebra mussel introductions and pollutant pathways linked to legacy contamination at sites like Waukegan Harbor.

Key Findings and Recommendations

The study identified chokepoints at locks on the Welland Canal and modernization needs at the Sault Ste. Marie Canal to support vessel drafts serving markets in the Midwestern United States and Ontario. It recommended coordinated capital investment programs engaging the St. Lawrence Seaway Management Corporation and the Great Lakes St. Lawrence Governors and Premiers to leverage funding from instruments like the Canada Infrastructure Bank and federal appropriations from the United States Congress. Operational recommendations emphasized harmonizing icebreaking schedules by the Canadian Coast Guard and the United States Coast Guard, improving contingency planning with the International Maritime Organization frameworks, and enhancing ballast water management consistent with guidelines from the International Maritime Organization and scientific guidance from the International Joint Commission.

Economic and Environmental Impacts

Economic assessments projected impacts on freight corridors serving manufacturing centers such as Detroit, Hamilton, and Cleveland, agricultural exporters in Minnesota and Saskatchewan, and energy supply routes to facilities near Sarnia. Forecasts weighed effects on sectors represented by the Chamber of Marine Commerce, the American Association of Port Authorities, and labor organizations such as the International Longshore and Warehouse Union. Environmental impact analysis emphasized trade-offs for habitats in the Laurentian Great Lakes basin, wetlands protected under designations like the Ramsar Convention in regions including Point Pelee and the Long Point National Wildlife Area, and implications for fisheries managed under agreements with the Department of Fisheries and Oceans Canada and the National Marine Fisheries Service.

Implementation and Policy Response

Responses included programmatic collaboration among the Great Lakes Fishery Commission, the International Joint Commission, and provincial bodies such as the Ontario Ministry of Transportation to phase capital projects and regulatory changes. Legislative follow-through involved hearings before committees of the House of Representatives (United States) and the Parliament of Canada, with funding proposals debated alongside infrastructure initiatives like the North American Free Trade Agreement-era trade adjustments and later frameworks tied to the United States–Mexico–Canada Agreement. Agencies instituted pilot projects on ballast water treatment consistent with Environment and Climate Change Canada guidelines and bilateral incident-response exercises with the U.S. Coast Guard Sector Detroit.

Criticisms and Controversies

Critics from environmental NGOs including Friends of the Earth, Sierra Club (U.S.), and regional groups like the Council of Canadians argued the study prioritized commercial throughput over protections for ecologically sensitive areas such as Sleeping Giant Provincial Park and the Apostle Islands National Lakeshore. Indigenous leaders from Mishkeegogamang First Nation and the Akwesasne community raised concerns about consultation processes and asserted rights under doctrines reflected in cases like Delgamuukw v British Columbia. Shipping industry stakeholders countered that delay in lock upgrades risked competitiveness for ports such as Port of Indiana-Burns Harbor and Port of Toledo. Disputes also arose over cost–benefit assumptions and modeling choices debated in venues like the International Joint Commission hearings and legislative committees in Ottawa and Washington, D.C..
