Some residents of southern and eastern Ontario were treated to Mother Nature's wrath Saturday night as some severe thunderstorms passed through the region.

One city caught in the unsettled weather was Oshawa where Durham Region Police have tweeted that a strong storm caused damage to several homes and vehicles.

There have also been reports of fallen trees and damage to some homes in Brampton.

Power utilities are reporting a number of sporadic power outages, though it's not clear whether all of them are weather related.

A tornado warning was posted for central Ontario but cancelled half an hour later, and severe thunderstorm warnings were issued for other parts of the province.

Environment Canada meteorologist Peter Kimbell says the agency has received calls from people who said tornadoes struck in the Oshawa, Brampton and Beaverton areas but it will be a couple of days before experts can confirm those reports.

Kimbell says the agency has also received reports of storm damage to some homes as well as a marina on Simcoe Lake.

Images posted on social media showed fallen trees and one home with a damaged roof.

The storms also gave some areas a good drenching, with up to 50 millimetres falling in some spots.

Kimbell says the moist, humid air is causing instability triggering the strong storms, but they started to peter out as temperatures started to cool.
