1 picture · 1977
- Founded
- 1882 (federal charter 23 September 1882); 1977 report states incorporation under the Companies Act of Canada on 30 July 1912
- Head office then
- 1155 Dorchester Boulevard West, Montreal (works at Lachine, Quebec)
Dominion Bridge fabricated and erected steel bridges and building frames from Lachine, with shops in Winnipeg, Amherst, Calgary, Edmonton and Vancouver. The 1977 head office was on Dorchester Boulevard in Montreal.
It was a principal Canadian bridge and building-steel fabricator for the CPR and for civic and industrial frames.
Why it mattered
It was a principal Canadian bridge and building-steel fabricator for the CPR and for civic and industrial frames. Lachine sat on rail and the canal. Quebec's cultural-heritage register treats the Lachine works as a major 19th–20th century plant.
Now
The Canadian fabricator was sold to Cedar Group in 1994. Dominion Bridge filed for creditor protection in 1998. There is no continuing Dominion Bridge steel company. The Lachine shop later closed.
Still open
- 1882 charter versus 30 July 1912 Companies Act date in the 1977 report: both appear in reliable sources; 1912 is likely a reincorporation.
- Wikipedia's 2001 SPX date refers to United Dominion Industries, the former parent, not the 1994–98 Dominion Bridge fabricator.
- Exact closing date of the Winnipeg and Edmonton shops after the 1998 filing is not independently confirmed beyond contemporary press notes.
