Temperatures in Toronto could feel like 44 C on Thursday, Environment Canada says, as the region braces for another wave of scorching heat this summer.
The city and parts of the Greater Toronto Area are under a heat warning that is expected to continue Friday and may extend through the weekend for some areas.
The hottest conditions are expected on Thursday, the federal weather agency said in a statement Thursday morning. Daytime high temperatures are expected to reach 35 C, with the humidex making it feel like up to 44 C.
Nighttime lows are expected between 20 to 23 C, which Environment Canada said will provide little relief from the heat.
On Friday, daytime high temperatures are expected near 30 C. The humidex may make it feel near 40 C.
Nighttime lows are expected near 21 C.
"While daytime high temperatures will not be as extreme on Friday and into the weekend, nighttime lows are expected to remain warm throughout," Environment Canada said.
The heat warning is also in effect for Vaughan, Richmond Hill, Markham, Mississauga, Brampton, Halton Hills, Milton and Oakville.
Check in on those at risk of heat illness
Environment Canada is advising people to limit exposure to sun and heat by planning activities during the coolest parts of the day, as well as wearing a wide-brimmed hat and lightweight, light-coloured, loose fitting clothing.
People are advised to watch for symptoms of heat stroke, which is a medical emergency, in themselves and others. Symptoms can include red and hot skin, dizziness, nausea, confusion and change in consciousness.

As the GTA's heat wave rages on, some residents have been struggling to stay cool. CBC's Dale Manucdoc speaks to Torontonians living in buildings without air conditioning and those who have no choice but to work outside.
"While you wait for medical attention, try to cool the person by moving them to a cool place, removing extra clothing, applying cold water or ice packs around the body," Environment Canada said in Tuesday's warning.
The weather agency also advised people to drink water often, even before feeling thirsty, and close blinds and open windows if the outside is cooler than inside.
"If your living space is hot, move to a cool public space such as a cooling centre, community centre, library or shaded park," the heat warning says.
People are also advised to check in regularly on those at greater risk of heat illness, including the elderly and those living alone.
Signs of heat exhaustion may include headache, nausea, dizziness, thirst, dark urine and intense fatigue. If you experience these symptoms, Environment Canada advises stopping your activity and drinking water.
