Ken Hartwick, ICD.D
Ken Hartwick and his wife, Linda, have made Milton their home for the past 36 years, raising three children and immersing themselves in the fabric of this tight-knit community through their church, various charities, and youth sports.
Recently retired as President and CEO of Ontario Power Generation, Ken led the most significant growth mandate in the company’s modern history, which included advancing the continent’s first small modular nuclear reactors, major refurbishments of its nuclear and hydroelectric fleets, and launching Canada’s first utility green bond. He also expanded OPG’s focus beyond generation to electrification services and nuclear partnerships around the globe.
Under Ken’s tenure, OPG released its first-ever Climate Change Plan, Indigenous Reconciliation Action Plan, and transformed itself into one of Canada’s best diversity employers, including assembling an executive team, more than half of which is comprised of women. Ken joined OPG from Wellspring Financial Corporation, where he was CFO and Treasurer. He held various senior positions in the energy sector, including interim President and CEO of Atlantic Power Corporation, CFO and CEO of Just Energy Corporation, and CFO of Hydro One. Ken also previously held senior positions at Capgemini and was a partner at Ernst & Young LLP.
He is a Chartered Professional Accountant with an Honours Bachelor of Business Administration degree from Trent University, serves on several boards, and was recently named Senior Fellow of the C.D. Howe Institute.

Ken grew up with five siblings on a dairy farm in Norwood, just east of Peterborough. It was there he learned the value of hard work and the importance of community. He also met and married Linda in Norwood. It was through Linda, a dedicated nurse for 40 years, that Ken learned the profound impact of compassionate, end-of-life care. And their personal experiences with loved ones fueled their belief that every individual deserves to live their final days with dignity and comfort.
An avid sports fan, Ken also coached Milton boys’ and Halton girls’ hockey teams. As a former goalie himself, and despite his misguided love of the Boston Bruins, Ken has always believed that hockey, like farming, teaches you how to work in a team and how to be something bigger than yourself.
