High winds and rain whipped through southern Ontario Sunday afternoon, taking down hydro lines, toppling trees onto cars and affecting public transportation.
At one point on Sunday evening, tens of thousands of customers were without power in the Greater Toronto Area.
Some roads in the GTA were closed due to downed power lines and a tree on the Lakeshore West train line caused cancellations and delays for GO Transit users.
In Waterloo, Ont., strong winds knocked down at least four homes under construction in the city’s Vista Hills neighbourhood.
There were also reports of uprooted trees and damage to homes and vehicles in London, Ont.
Environment Canada had issued widespread warnings about wind gusts of up to 90 km/h.
People shared photos of videos of the intense storm and its aftermath on Twitter.
