Thousands are without power as severe storms sweep across much of southern Ontario.
Environment Canada issued a severe thunderstorm warning Sunday night for Toronto and much of the Greater Toronto Area.
The weather agency said the GTA could see between 50 and 75 millimeters of rain and wind gusts of up to 70 km/h.
Hydro One said Sunday evening that about 26,000 customers are currently without power due to the storms.
“Crews are working as quickly and safely as possible to restore power,” the company said.
Environment Canada warned that heavy downpours could lead to flash flooding and water logging on roads.
“If visibility is reduced while driving, turn on your lights and maintain a safe following distance. Severe lightning is likely with any storm that develops. Avoid driving through water on roadways,” the statement said.
Strong storms follow days of intense heat. A heat advisory remains in effect for Toronto and many other areas, with temperatures approaching 40C for several days.
The sweltering heat is expected to ease tonight, with a cooler high of 23C expected on Monday.
