The uncomfortable weather that has descended on Toronto should start moving off by Saturday, but not before some rain and thunderstorms drench the region.
Environment Canada said severe thunderstorms hit Toronto between 6 and 7 p.m. and more rain may happen overnight.
In Toronto there were numerous reports of downed power lines and snapped tree branches.
There was also some damage from storms earlier in the afternoon reported in areas north of Toronto including Barrie, Gravenhust, Bracebridge and Coldwater.
The storms moved quickly — at about 80 km/h — producing high winds and torrential rains.
The storms and high winds will probably be the last gasp of the heat wave that has broiled the city for the past five days.
Temperatures stayed in the mid-30s for most of the week. And with the humidity figured in it felt a lot more like 40 C, or higher.
The city declared an extreme heat alert, opening cooling centres, advising people to look after themselves and check on elderly neighbours, and keeping many neighbourhood swimming pools open late into the evening to help people stay cool.
But on Saturday the sting from the heat is expected to fade.
Environment Canada is forecasting a beautiful, sunny summer weekend for Toronto with a high of 27 C and an overnight low of 15 C.
