The Trillium class ships featured highly automated systems and greater fuel efficiency and capacity than their other CSL fleetmates. Her sisters were the Baie St. Paul {2}, Whitefish Bay {2}, and Baie Comeau {2}, and the gearless Trillium vessels CSL Welland and CSL St-Laurent.

Her self-unloading equipment consists of a dual hold belt leading to an aft loop-belt system to a 260′ deck-mounted boom.

Her Story

The Thunder Bay was constructed in 2013 as the second member of the Trillium Class ship for Canada Steamship Lines. The Thunder Bay was the second of 6 Trillium class ships constructed and the second of four self-unloading Trillium class ships. She was christened Thunder Bay on June 11, 2012, being completed on May 25, 2013, and departing China for Canada on May 29, 2013. She arrived at Montreal on August 25, 2013 where final preparations upon her entering of service were completed. She sailed up the St. Lawrence Seaway on July 30, 2013, to unload her cargo of ballast stone at Windsor, Ontario.

The Thunder Bay was upgraded to Nova Scotia class certification in February of 2020 while receiving a routine drydocking and inspection. Additional hull strengthening was fitted while in drydock.

The Thunder Bay continues to be an active member of the Canada Steamship Lines fleet, hauling ore, coal, stone, grain, and salt across ports on the Great Lakes and Canadian east coast.
