Topping 10 million tonnes of cargo in 2024 — including grain above 4.9 million tonnes and potash over 1.2 million tonnes — Thunder Bay (CA THU) ranks among the busiest bulk ports on the Great Lakes. Sitting at the western end of the Great Lakes–St. Lawrence Seaway, it gathers Prairie wheat, canola and other grains in a cluster of elevators and loads them onto lakers and ocean vessels heading east. Two dry-bulk terminals also export Saskatchewan potash — the only potash loading facilities on the entire Seaway system — and 2024 was the strongest potash year in four decades. Coal, general and project cargo move through the Keefer Terminal. Transcontinental rail (CN, CP) and the Trans-Canada Highway tie the port to Western Canada's interior. It is not a container port; boxed cargo routes via Montreal or the West Coast ports of Vancouver and Prince Rupert. Operations are seasonal, since the Seaway closes for ice from roughly January to March.
