Major Event Response Reports


Major Events are extraordinary occurrences out of a distributor’s control that cause significant disruptions in the distribution system.

A major event is beyond the control of the distributor and is unforseeable, unpredictable, unpreventable or unavoidable. Examples are major weather-related events such as ice storms, major floods and tornadoes.

When a distributor determines an outage was caused by a Major Event, it must file a report with the Ontario Energy Board (OEB) that outlines its responses to questions regarding the Major Event. A distributor is required to file this report with the OEB within 60 days of the end of the Major Event and post this report on its website at the same time it is filed with the OEB.
