About 900 Hydro One customers in the Kenora area are still without power — and the company says power may not be restored until 10 p.m.

A Hydro One official said to restore power to the hundreds of customers still without electricity, crews must deal with 27 incidents, and they are travelling from one problem to another in areas that are sometimes far from each other and hard to access.

Crews have been working on restoring power since a thunderstorm on Tuesday night hammered the area, knocking out electricity to about 3,600 customers.
