Each year, On-Site magazine publishes the Top Contractors report – a database of the leaders among Canadian construction firms whose primary focus is the provision of general contracting services.

Company rankings are arranged by reported or publicly available revenue figures associated with work conducted within Canada. Participation is open to all Canadian companies as well as international companies who have a significant presence in Canada’s general contracting community. This should include a Canadian-based workforce and a physical office in an industrial or commercially zoned structure within Canada. Revenues listed should be for work conducted in Canada between Jan. 1 and Dec. 31 of 2023, or in alignment with the company’s most recent fiscal year-end reporting (either ending in 2023, or prior to April 29, 2024).

When filling out your survey, please include full contact information and sector activities as company listings will be published in our June issue, as well as hosted on our website. These listings will include contact information for your company, as well as your areas of expertise. Companies that do not provide a list of service offerings may only receive a basic listing for their company, so please checkmark all applicable services.

The company listings section is open to all General Contractors in Canada, regardless of size or revenues, so even if you do not expect to be in the Top 40, please fill in your company’s information as the free listings are an invaluable resource for owners, developers and other construction stakeholders looking to identify (and work with) Canadian contractors. As always, the listings are entirely FREE!

Also included in the section is a focus on smaller contractors. Companies with up to 50 employees will be included in our Top 5 under 50 section, also based on self-reported revenue or construction volume managed (in Canadian dollars).

DEADLINE: May 6, 2024
