Board of Directors

​The IESO is governed by an independent board of directors that oversees its business and affairs. The IESO Board also approves the Market Rules, policies and guidelines that govern the IESO-administered markets.

The members of the IESO's Board bring diverse backgrounds in economics, finance, business, electricity, gas, academia and technology, and are prohibited from having a material interest in a market participant. They were appointed by the Minister of Energy to serve as the Board of Directors for the merged IESO, effective January 1, 2015.
