Thunder Bay Shipyard

Located at the Western Canadian terminus of the St. Lawrence Seaway System, we intend to develop our Thunder Bay Shipyard so that it becomes the shipyard of choice in the northwestern Great Lakes.

Heddle Shipyards purchased the facility in 2016 and intends to make a significant investment to reanimate this historic shipyard, creating a top-service facility. Equipped with a Seawaymax graving dock and large fabrication shops, Thunder Bay is well situated to provide repair and re-fit services.  

Berthage at Heddle Shipyards Thunder Bay provides our customers a strategic winter layup location.
