24 Hour Emergency Service

24/7 Emergency Service Number


Cornwall Electric has a strong and reliable electricity system, but occasionally we are at the mercy of the Canadian climate.  In the winter, heavy snow or ice storms can cause power lines to break, while in the summer and fall, fierce winds, rain and lightning can cause extensive tree damage that leads to power outages.
In the event the power goes out, we have a six-step recovery plan in place to restore power to you, the customer, as quickly and safely as possible.

Cornwall Electric's 6- step power recover plan

1. Contact

We often learn about a power outage when someone calls our Customer Service Centre, which is open 24 hours a day, 365 days a year.  If you’re power goes out, please call our customer service centre immediately to notify us of an outage.  The appropriate personnel will be notified, and a crew is sent out to assess the situation.
Phone Numbers:
 Cornwall 1-844-701-9473

2. Emergency Restoration

 We receive many calls during an outage and they are addressed in priority. Our first priority is to respond to 911 emergencies like fires or live lines that are down. We then focus on restoring electricity to essential services such as hospitals, fire and police stations, and water and sewage treatment facilities.

3. Prioritize

Guided by the rule “do the greatest good for the greatest number,” we repair large system elements that serve a large number of customers, and then move on to repair individual lines serving individual customers.

4. Mobilize

 We assess the nature and extent of the storm-related damages so that we can quickly mobilize and deploy human and equipment resources from across the province, if needed, to the storm damaged area.

5. Communicate

 During a power outage, the Cornwall Electric communications department provides Estimated Time of Restoration (ETR) bulletins to the media and local officials.  As soon as the problem is diagnosed, Cornwall Electric will be able to provide our customers with updated information concerning the cause, the area affected, and the approximate time the power will be restored.

6. Finish the Job

 Cornwall Electric crews, management and dispatchers stay on the job until we have restored power to everyone. Then we revisit any temporary repairs.
