Major Events

After a major event such as a large-scale power outage, Hydro Ottawa compiles a report which is filed with our regulator, the Ontario Energy Board (OEB), normally within 60 days of occurrence.  These reports outline our response to major events.

Below you will find all Major Event Response Reports that have been filed with the OEB since this requirement came into effect on May 3, 2016.
