Notes: All price data is quoted in Canadian dollars and uses Eastern Standard Time. For the purposes of data reporting, the IESO does not adopt daylight saving time.

The IESO makes every reasonable effort to keep the prices appearing on this web page consistent and up to date with those prices used for settlement purposes. Should a discrepancy arise, the IESO will determine the appropriate price as quickly as possible and notify market participants of the change.
