(Thank you for the question, Elias!)

The Biggest Civil Engineering Companies in Canada

What are the biggest civil engineering companies in Canada (specifically, Ontario)? This question can be answered in several ways.

The largest employers of civil engineers, for example, are probably not “civil engineering” companies at all, but government agencies or larger multidisciplinary engineering and construction companies. The largest Canadian civil engineering companies by gross revenues may be a better metric, but they may not be the largest employers of civil engineers and many are still privately held. Lastly, we considered the “largest Canadian civil engineering firms” by number of employees, but again, that would have limited the scope of the list to only civil engineering companies, missing the wider construction or (especially relevant in Canada) energy industry companies.

Below is our loosely-organized list of the highest grossing, largest, or otherwise-employs-the-most-Civil-Engineers-in-Canada list of companies.


They are Canada’s largest publicly traded construction company and operate primarily in Canada (but are now performing some work abroad). Their headquarters are in Toronto, Ontario and, on the West coast Calgary, Alberta. They have 29 subsidiaries and employ over 10,000 people. You can view their landmark projects here.
