Cargo tonnage through the St Lawrence Seaway saw a decrease to 36Mt in 2022, with declines in grain, iron ore, coal, and general cargo. The Canadian St. Lawrence Seaway Management Corporation (SLSMC) and U.S. Great Lakes St. Lawrence Seaway Development Corporation (GLS) have released estimates for total traffic over the Seaway for the 2022 navigation season. The last commercial transit of the 2022 navigation season through the Montreal-Lake Ontario section of the Seaway occurred on January 1st, with the Welland Canal closing on January 9, 2023, marking the end of the fourth year of the Welland Canal season extension pilot program.
The cargo results included a 16.5% decline in coal traffic and a 21.52% drop in general cargo, while dry bulk volumes were up 2.8% and liquid cargo increased by 9.85%. Trends within each cargo type were noted, including significant growth in potash, increased petroleum products due to passenger travel, and a mixed performance in grain exports.
Seaway officials highlighted the system’s ability to adapt to market changes and capitalize on emerging opportunities, such as shifting trade patterns. They emphasized the importance of collaboration with partners to develop lands along the Seaway for economic and community benefits.
Despite some uncertainty regarding economic growth in 2023, the Seaway Corporations remain optimistic about the expansion of trade on the Great Lakes. Initiatives are in place to support this growth, including the establishment of green shipping corridors, land development, and the adoption of innovative technologies like the Vessel Information System.
Overall, the Seaway System is viewed as a resilient and sustainable shipping corridor that is well-positioned to navigate global supply chain disruptions. The focus on continuous improvement and agile performance makes the Seaway a relevant transportation system today and an essential part of future solutions.
