CA THU Port (Thunder Bay) – Terminals, Draft, Agents

About This Seaport

Thunder Bay (CA THU) handled over 10 million tonnes in 2024 — grain above 4.9 million tonnes and potash over 1.2 million tonnes. The 2026 season is one of the strongest in decades: more than 2.3 million tonnes of grain moved through by end of May 2026, the highest volume for that point in the season since records began in the early 1990s; July 2026 set a modern monthly record above 1.32 million tonnes. Year-to-date volumes through September 2026 are tracking roughly 11 percent above the same period in 2024, with monthly grain shipments in September adding approximately 500,000 tonnes year-on-year. Sitting at the western end of the Great Lakes–St. Lawrence Seaway, the port gathers Prairie wheat, canola and other grains in cluster elevators and loads them onto lakers and ocean vessels heading east. Two dry-bulk terminals export Saskatchewan potash — the only potash loading facilities on the entire Seaway system. Coal, general and project cargo move through the Keefer Terminal. Transcontinental rail (CN, CP) and the Trans-Canada Highway connect 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, the Seaway closing for ice from roughly January to March.
