Dominion Bridge Company Limited was a Canadian steel bridge constructor originally based in Lachine, Quebec. From the core business of steel bridge component fabrication, the company diversified into related areas such as the fabrication of holding tanks for pulp mills and skyscraper framing. The Dominion Bridge facility in Burnaby, BC operated from 1930 until the mid-1970s at a 15-acre (61,000 m2) property located at 2400 Boundary Road. After being sold, this property was repurposed to become The Bridge Studios, the site of the largest special effects stage in North America.
