Power is back on in the Kincardine and Tiverton areas.
Hydro One spokesperson Danielle Gauvin says just over 200 customers lost their power shortly before 8:30 AM.
It was restored shortly before 11:30 AM.
Gauvin says a tree came down in Tiverton that broke the cross-arm of a hydro pole resulting in the outage.
Crews have since repaired the damage and power is back on.
