EllisDon celebrates 70 years of business

70 years ago, EllisDon was established in London, Ontario by brothers Don and David Ellis Smith. Today, EllisDon celebrates and looks back—from their first project for a small home renovation, to becoming a construction, building services and technology company with over 5,000 salaried employees.

In 1956, EllisDon brought the first tower cranes to Canada. In 1986, EllisDon was awarded the design-and-build contract for Toronto's SkyDome, making history by building the world's first retractable-rooftop stadium.

In 70 years of business, EllisDon has expanded beyond construction to deliver on any aspect of a project, leading projects all the way from the initial concept phase to long-term asset management, operations and smart buildings technology. These services are called "Cradle-to-Grave" and continue to grow and challenge traditional views of what it means to be a company in the construction industry.

In 2020, EllisDon announced a final agreement was executed under which 100 percent of the company's equity will be transferred to the company's employees. From March 1, 2020 onward, EllisDon will gradually buy out the Smith family stake, enabling the employees' equity ownership to increase to 100 percent over several years.

EllisDon continues to make advances in areas like inclusive diversity, with the creation of multiple new employee groups including: ABEEL (Alliance of Black Employee Experience and Leadership) which educates employees and sub-trades on anti-Black systemic racism; the Gender Equality Group, 2gether (2: Balance Harmony Gender Equality Team Human Empowerment Redefined) to set in motion plans to achieve equitable opportunities for everyone, and ALLiED (ALL inclusive at EllisDon) a group of volunteers committed to spreading the word of inclusive diversity.
