Where this data comes from
Numbers on this page come from Hydro One's public outage data — the same data behind its official outage map — collected on a rotating cycle (each utility typically refreshes within the hour; the card above shows exactly when these numbers were last collected). When the utility posts a restoration time we show it as the official estimate; our independent estimate is computed from the outage's own recovery trend and graded publicly. The level of detail is whatever Hydro One's own map publishes: some utilities place each outage near a community, others report only their own service areas, which can span several towns.
Not affiliated with Hydro One. Report outages and downed lines to the utility directly via its official outage site ↗ — never rely on this page for emergencies.
Common questions
How do I report a power outage to Hydro One?
Report outages and downed lines directly to Hydro One through its official outage site or its outage phone line — crews are dispatched from customer reports. This page is an independent tracker, not affiliated with Hydro One; never rely on it for emergencies. In a life-threatening situation, call 911.
Does Hydro One give an estimated restoration time?
When Hydro One posts an estimated restoration time for an outage, we show it as the official estimate. Alongside it we show our own independent estimate from the outage's live recovery trend — useful when the utility hasn't posted a time yet. Both appear side by side.
Why isn't my outage showing for Hydro One?
A brand-new or single-customer outage may not appear in the utility's public data yet, and this page can only be as detailed as Hydro One's own outage map, which may report a whole service area rather than your street or town. If your power is out and it isn't listed, report it to Hydro One so it enters their system.
How accurate is the Hydro One restoration estimate?
Our independent estimates are graded against when the tracked outage was substantially restored (~90% of customers back), published on our accuracy page. Hydro One's own posted restoration times are graded there too, so you can compare them.
