Dominion Bridge Company
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.
Other Canadian plants were located in Amherst, NS, Toronto, ON, Winnipeg, MB, Regina, SK, Saskatoon, SK, Calgary, AB, Edmonton, AB, Richmond, BC and Burnaby, BC. In the 1960s and 1970s, Dominion Bridge expanded internationally and renamed itself AMCA International (AMCA name effective June 1, 1981). This name was later changed to United Dominion Industries. To keep name recognition alive, the company continued to call its Canadian division 'Dominion Bridge'. Between 1979-1988, the company's Lachine plant operated under the auspices of a subsidiary called Dominion Bridge-Sulzer Inc., which was co-owned by AMCA International and Sulzer Inc.
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.
In 1886, the company began to build a cantilevered bridge over the St. Lawrence River for the Canadian Pacific Railway. Because part of the bridge lay in the reservation of the Kahnawake and Akwesasne Mohawks, the Mohawks demanded jobs on the project. The company planned to use them as unskilled labour but they climbed all over the bridge, without fear, and asked to become riveters. They proved to have a remarkable aptitude for the work and by the end of the project there were 70 iron and steel riveters in the Kahnawake band, who went on to work on projects throughout Canada.
