EllisDon celebrates its 75th anniversary April 1, an evolution from a four‑person contracting business in London to a global, 100 per cent employee‑owned construction and building services company.
“For 75 years, EllisDon has been proud to serve as a trusted infrastructure delivery partner to federal, provincial, and municipal governments across Canada,” said Kieran Hawe, president and chief executive officer, EllisDon. “Working in close collaboration with public sector clients, we deliver essential projects that support economic growth, strengthen communities, and enhance quality of life for Canadians from coast to coast.
“As the company marks this milestone anniversary, EllisDon’s commitment to public infrastructure underscores our dedication to fostering resilient, sustainable communities and advancing Canada’s future through innovative construction solutions.”

The company’s first contract was Northdale Public School, a three-room public school in London and defining projects include Rogers Centre, Toronto’s Port Lands redevelopment, energy initiatives like Manitoba’s Keeyask Hydroelectric Generating Station, complex defence facilities, shipyard infrastructur, and large‑scale data centres.
With more than 10,000 employees worldwide, EllisDon has expanded its capabilities across development, construction, technology, capital, operations, and facilities maintenance, as well as the continued commitment to safety, sustainability, diversity and inclusion.

“Our 75-year journey has shown us that when people feel genuinely invested, it transforms the employee experience,” said Paul Trudel, Chief People Officer & SVP, Marketing and Communications, EllisDon. “Employee ownership creates a sense of shared purpose, knowing we’re building something together, and strengthening our culture, generation after generation.”
Recognizing the people and partnerships will be a key part of marking the anniversary which reflects a “forward‑looking focus on meeting evolving community needs, supporting continued global growth and helping shape the built environment for generations to come.”
