Nearly 1,500 customers remain without power in the western portion of the region.
As of Thursday morning, Hydro One's storm centre map is reporting 28 separate power outages spanning from the Manitoba border, including the Kenora and Sioux Narrows-Nestor Falls areas after an overnight storm.
The estimated restoration time varies for each outage, with some expected to take until the evening to be restored.
As well, the Township of Sioux Narrows-Nestor Falls has closed the White Moose Golf Course on Thursday due to the storm damage, which includes fallen trees and overhanging branches.
The municipality said phone lines are also down.
