Canadian Shipbuilding & Engineering

Port Weller Dry Docks was a shipbuilder located on the Welland Canal at the Lake Ontario entrance. The shipbuilder was founded in 1946 and the site was initially owned by the Government of Canada for storage purchases. The shipyard expanded to include ship repair, and reconstruction work. In 1956, the drydock was sold to the Upper Lakes Shipping Company, which began the construction of vessels at the site. The shipyard twice went insolvent, most recently in 2015. Port Weller Dry Docks was used to build, refit and repair cargo vessels.

Following the boom of shipbuilding on the Great Lakes during the Second World War, the Muir Dry Dock was closed down at Port Dalhousie, Ontario and operations were moved to the east side of the Welland Canal at Port Weller, Ontario in 1946. The drydock, opened in 1947, was initially owned by the Government of Canada and was used to store gates, lock valves, and gate-lifting vessels. The new site was considered an improvement over the Muir Dry Dock due to its location above Lock 1, which eliminated the need for pumps to fill or empty the dry dock. The yard was expanded to include ship repair and reconstruction work and employed 500 by 1950. In 1956, the yard was sold to the Upper Lakes Shipping Company. Under their management, the shipyard began to construct vessels of different types, such as bulk carriers, tankers, tugboats, scows, barges, car ferries and icebreakers. The Port Weller Dry Docks expanded its activities with the opening of the Saint Lawrence Seaway in the late 1950s. By the 1990s, the Port Weller Dry Docks was the lone Great Lakes shipyard in operation in Canada.
