High winds within the area prompted reports of trees down on Hydro One equipment resulting in broken poles and lines down.
Crews have been brought in from surrounding areas to assist in power restoration.
The utility says the majority of customers will have power restored by 2 p.m. today and all should be done by 5 p.m.
