High winds and heavy snow have caused hundreds of power outages across Ontario.

Hydro One says roughly 370 power outages has affected more than 50,000 customers.

The company says damage assessors and repair crews have been mobilized but it is not known when power will be fully restored.

Power has been restored for some 6000 residents in Haldimand and Simcoe regions.

Environment Canada issued a special weather statement for Southern Ontario on Friday with the return of winter-like weather.

The agency says conditions are expected to rapidly improve later Friday morning as the snow ends and temperatures rise above zero in all areas.
