Who We Are

Innovation in Action, Integrity at Heart

For 50 years, Kenaidan has been a proud industry leader providing comprehensive construction services across all market sectors. Born out of the hard work and innovative vision of founders Ken Smith and Aidan Flatley in 1974, we’ve grown from a two-person operation to a team of hundreds. Despite all the growth and changes, we haven’t lost sight of what’s important, and we continue to uphold our founding principles to work hard, maintain integrity, and foster a positive work environment for our dedicated team.
As part of the Obayashi global family since 2011, we leverage their resources and experience to contribute to large-scale projects while maintaining our independent spirit. We manage our operations from our offices in Mississauga, Ontario, and Richmond, British Columbia. Guided by our core values of integrity, operational excellence, a commitment to action (CETA), and a positive work environment, we strive each day to deliver quality work and nurture our valued workforce.
