On-Site Magazine


On-Site’s Top Contractors report is dedicated to determining the leading construction contractors in Canada, ranked by revenue. It is an invaluable tool based on direct research of the companies involved and is used throughout the industry to research and source leading contractors.

Following a year dominated by COVID-19, On-Site is proud to present its 2021 Top Contractors report. It shows the industry’s well-earned reputation for resilience as contractors adapted on the fly to project-stopping lockdowns, supply chain challenges and new ways of communicating. The industry also came together, uniting behind standardized health and safety protocols, while putting aside the usual competitive attitude to share best practices and keep workers safe.

Despite facing down the global pandemic, many of Canada’s Top Contractors saw their revenues climb in 2020, demonstrating how the health crisis did little to lessen demand — or stop work — throughout the industry. Procurement for a number of major projects did slow last year, and certain private owners understandably pumped the brakes on upcoming jobs, but a stabilizing economy and government stimulus spending has builders looking deeper into 2021 and beyond with growing confidence.

We thank all of the contractors that took the time to participate in our annual survey. Your valuable contributions make this research possible.
