What to do during a power outage in Ontario
Whether you live in an urban centre or rural Ontario, the actions you take in the first 30 minutes are the same. Identify if the outage is yours alone, protect what is at risk, and report what you know.
1. Check neighbours and breakers
If streetlights are on and neighbours have power, check your main breaker. If the whole block is dark, it is a grid event.
2. Call your distributor
Use the verified phone numbers above. Have your account number or service address ready. Report on this page’s map too.
3. Protect food and electronics
Unplug sensitive electronics. Keep fridge and freezer doors closed — food stays safe ~4 hours in a fridge, ~48 hours in a full freezer.
4. Stay warm safely
In winter, layer clothing and use blankets. Never use a gas stove or BBQ indoors. Generators must run outside, 6 m from doors and vents.
Are you eligible for compensation in Ontario?
Hydro One and LDCs operate under Ontario Energy Board reliability standards. No automatic credit, but persistent reliability failures can trigger Service Quality Indicator complaints to the OEB.
Are you eligible right now?
Most one-off outages do not result in a credit. If your distributor has chronic reliability issues, file an OEB complaint. Damaged appliances and food spoilage claims are accepted case-by-case by the LDC.
How to file:
- Document the outage: start time, end time, photos of spoiled food and damaged appliances, receipts for replacement purchases.
- Submit a claim through your distributor’s claims page (linked in the “who to call” section above) within 30 to 60 days.
- If your claim is denied or stalls, escalate to the Ontario Energy Board — they have authority over the utility.
