Heavy winds brought down power lines, knocked over trees and resulted in a handful of road closures late Monday afternoon and early Monday evening.

The winds, which were clocked at about 70 kilometres an hour in Toronto, were part of a cold front moving in from Western Ontario.

They are being blamed for scattered power outages throughout the city that have left about 300 people in the dark as well as a bizarre incident at the Pantages Hotel, where police had to close down a nearby intersection at around 8 p.m. while a dislodged window was popped back into place.

"The high winds picked up the window and pushed it outwards and we had to close off Shuter Street between Yonge Street and Victoria Street for a short period of time to protect the public from falling glass," Sgt. John Margetson told CP24 at the scene. "Luckily nothing fell and nobody was hurt."

The winds, which were felt throughout Southern Ontario, caused Environment Canada to issue a wind warning at around 2 p.m.

That warning ended at around 9 p.m.

Highway 400 temporarily closed due to winds

The heavy winds also caused at least one accident on Ontario roads.

At around 3:20 p.m. a tractor-trailer travelling along Highway 400 tipped onto its side at Canal Road near King City.

The driver was unharmed, but all southbound lanes on Highway 400 between Highway 88 and Highway 9 were closed as police cleaned up the scene.
