This map, updated every 15 minutes, includes information on power outages affecting ten or more customers that reside within 200 metres of each other.

This map does not include momentary outages, also known as ‘auto-reclosures’. This is when a Hydro Ottawa circuit breaker at a substation opens momentarily to allow a temporary fault or problem on the distribution system to clear (e.g. lightning strike or tree branch contact). The circuit breaker then "auto-recloses" to restore power thus avoiding a prolonged power outage or the dispatch of field personnel to restore power. Learn more about what can interrupt the flow and supply of electricity.

Planned work projects that include power outages or transferring power to another circuit in order to allow our crews to safely conduct upgrades, maintenance or repair work are displayed. We provide customers with prior notice before we interrupt service, with some exceptions such as emergency situations.

Unconfirmed outages also appear on the map. These are areas that we have identified as possibly being without power, but have yet to confirm.
