News and Notices

A key part of the IESO's mandate is to ensure that market participants, interested stakeholders and the general public are informed of key issues and activities central to the evolution and operation of Ontario's wholesale electricity market.

All IESO email communications since the market opened in 2002 are catalogued on this page. Communications are organized into several main subject areas accessible through the drop down list below.

The IESO publishes a weekly bulletin that is sent to all subscribers each Thursday. The IESO Bulletin consolidates important news, notices, updates and upcoming events into one email. In addition to the weekly bulletin, urgent or time-sensitive communications are delivered on an as-needed basis and sent to the appropriate contact lists.
