Chief Administrative Officer

Bill Rayburn was born and raised in North Bay, Ontario where he met his wife Cheryl. Bill has a number of diplomas and degrees in public administration including an undergraduate degree from Queen’s University in political science and a Master’s degree in Public Administration from the University of Western Ontario.

Bill started his career as the Chief Administrative Officer of Cobalt, Ontario at the age of 23. Eighteen years later, Bill is a veteran of municipal government after spending the last thirteen years guiding the County of Middlesex as their Chief Administrative Officer.

In addition to working with municipalities, Bill led one of the largest pension funds in North America from 1998 - 2005. As a member of the Executive Committee of OMERS since 1998 and the Chair of the Board in 2003, Bill guided the $43 Billion fund through a turbulent and challenging portion of OMERS 40 year history.

While Bill has slowed down his international public speaking engagements in recent years, his presentations regarding utilizing private sector financing to build public sector infrastructure have brought him around the world several times to locations from California to China. However, the traveling that Bill is most proud of are his trips to Russia to adopt his son Aidan and his daughter Karina.
