Seaway synergy: Highway H2O unlocks Great Lakes potential
Competitive shipping relies upon resiliency, reliability and redundancy. Coupled with the opportunities that geopolitics, European Union and United Kingdom policies and shifts in trade partnerships bring, the Great Lakes hold potential opportunities not seen in the past decades.
The 20th annual Highway H2O Conference drew a crowd to Toronto for three days of discussion about these topics and the future of the bi-national St. Lawrence Seaway. The Seaway’s unique shared governance between Canada and the United States framed the event, reminding attendees that decisions on one side of the border ripple across all the Great Lakes. SSGA Director of Transportation & Regulatory Affairs Gary Williams attended and spoke at the event, hosted jointly by the St. Lawrence Seaway Management Corporation (SLSMC) and the U.S. Great Lakes St. Lawrence Seaway Development Corporation (GLS).
The attendees reflected the system’s complexity and potential. They included leaders of the two operating entities of the Seaway, including Administrator Mike McCoshen from the GLS and SLSMC President Jim Athanasiou, alongside shippers, freight brokers and forwarders, port and terminal leaders, regulatory and governmental agencies, and other Lakes/Seaway stakeholders. Their conversations carried a common thread: capacity exists on the system today, but realizing its competitive edge will take coordination, investment and a new way of thinking about freight.
Williams presented about SSGA’s trade revitalization program designed to educate importers and exporters on the advantages of the Seaway and to actively address barriers that keep volumes below the corridor’s true capacity. The program is supported by the Ohio Soybean Council, Minnesota Soybean Research & Promotion Council, Wisconsin Soybean Marketing Board and Illinois Soybean Association.
At the heart of Williams’ story was the idea that the Seaway is not just an alternative route, but a strategic piece of a diversified transportation portfolio. He outlined how the corridor can complement rail, truck and coastal ocean routes, offering resilience, cost-competitiveness and environmental benefits that appeal to cargo owners looking for redundancy and lower emissions. Yet, he was direct about the challenge: lower current trade volumes can make it harder to build frequent services and justify new infrastructure, even though the physical capacity is already in place.
Containerization entered the discussion as both a challenge and an aspiration. While some attendees talked about the long-term goal of establishing a dedicated feeder system on the Lakes, Williams urged the group not to wait for a perfect future model. Instead, he encouraged them to build the container market incrementally, leveraging the flexibility of many vessels already entering and leaving the Seaway that can carry containers alongside other cargoes.
Williams invited stakeholders from across the value chain to join the trade revitalization program and deepen their understanding of the corridor’s potential. He pointed to the upcoming Transportation Go! conference April 8-9, 2026, in Chicago as a next touchpoint, encouraging participants to continue the conversation there and help shape solutions that turn today’s ideas into tomorrow’s sailings.
