Each year a cross-section of IESO market participants are surveyed to gain insight into the IESO’s strengths and weaknesses, and identify areas where improvements can be made.

The 2010 survey demonstrates that the IESO continues to be highly regarded by survey participants, and is considered by most to be a strong and influential leader in Ontario's electricity sector. Improvements to the Stakeholder Engagement process were noted and some areas for improvement were identified, particularly in terms of facilitating customer needs. This annual survey is very important to the IESO and is used to assess how well customers' needs are being met.
