What EllisDon does
EllisDon Corporation is a 100% employee-owned Canadian construction and building services company founded in 1951 and headquartered in Mississauga, Ontario. It operates through six service divisions — Capital, Construction (Buildings), Industrial, Civil, Services, and Technology — delivering design-build, construction management, public-private partnerships (P3), and long-term facility management across Canada, the United States, and the Middle East. The company serves federal, provincial, and municipal governments, institutional healthcare clients, and industrial customers in data centers, energy, pharmaceuticals, and defense, with a backlog exceeding $36B+ in total capital cost of financially closed P3 projects and 10,000+ employees across 16 global offices. Landmark projects include the Rogers Centre (SkyDome), the Keeyask Hydroelectric Generating Station, and the Peter Gilgan Mississauga Hospital (Canada's largest hospital project). Notable industrial concentration includes its self-described position as the #1 builder of data centers in Canada.
The company's technology backbone is Gate Three, a proprietary ERP/project management platform developed in-house with 35+ integrated modules, evolved from the Edgebuilder system that won the Canadian Information Productivity Awards Diamond Award of Excellence in 2003. A Digital & Data Engineering Division of 250+ technology professionals supports BIM modeling, reality capture, drone operations, and AI-powered analytics against the EllisDon data lake. Revenue is generated primarily through project fees, cost-plus arrangements, and fixed-price contracts, supplemented by recurring facility management contracts covering 20M+ sq ft of facilities and 30-year P3 maintenance obligations. The 100% employee-ownership structure (fully transitioned in 2020 under then-CEO Geoff Smith) and 75-year operating history are core to the company's value proposition of single-point accountability across the project lifecycle.
