Crews are still working to restore power to more than 48,000 Hydro One customers after high winds rattled parts of the GTA overnight.

Hydro One says high winds are to blame for 475 active power outages affecting customers in Owen Sound, Orangeville, Newmarket, Bracebridge, Bancroft, Huntsville, Perth, Tweed and Vankleek Hill.

“Crews have been working since last night to restore customers. We expect more outages to be reported as people get up this morning," Greg Kiraly, the chief operating officer at Hydro One, said in a news released Wednesday afternoon.

"All available employees are focused on restoring customers and responding to emergencies. Turning the lights back on for homes and businesses is our top priority."

Residents in Brampton, Toronto and Vaughan were also in the dark this morning after strong winds knocked down power lines and trees across the region.

Hydro One Brampton said approximately 2,786 customers were without power early this morning due to last night's weather conditions.

High winds knocked down hydro wires and trees across the GTA this morning. About 83 customers remain without power and the utility says power should be restored by 4 p.m.

Outages were also reported in the areas of Steeles Avenue and Hurontario Street as well as Queen Street and McLaughlin Road.

At around 6:30 a.m. Wednesday, Toronto Hydro tweeted that crews were working to restore power to a number of customers after high winds knocked out power across the city. The utility did not specify the exact number of customers that were impacted or the areas where the outages occurred.

More than 1,000 residents in Vaughan were also in the dark this morning after an overnight outage.

The power outage, which affected customers in the area bounded by Major Mackenzie Drive, Keele Street, Dufferin Street and Teston Road, left approximately 1,507 customers without power. Most of which has since been restored.

A wind warning issued for Toronto and parts of the GTA overnight, though terminated this morning, is likely to blame for the widespread outages.
