Health agencies advise people to alter their routines to stay safe in this dangerous heat, and Health Canada recommends staying cool and hydrated when extreme heat hits.
That can mean everything from drinking lots of water and planning outdoor activities for cooler times, to preparing meals that don't require ovens.
How to help your body cope in hot weather
Watch for signs of heat exhaustion — like a headache, dizziness or a rapid heartbeat — and get to a cool place where you can drink water. Heat stroke, which includes confusion and very hot or red skin, is a medical emergency requiring a 911 call.
More resources may be available through your municipality. Ottawa, for example, has a map of public and other places to cool off.
Gatineau is keeping its Guy-Sanche and Lucien-Lalonde libraries open Tuesday so people can take advantage of the AC. They would normally be closed for St-Jean-Baptiste.
People are asked to keep an eye on elderly neighbours and other vulnerable residents.
Humidity to drop Wednesday
Tuesday night's forecasted low in Ottawa is 20 C.
The humidity may break overnight Tuesday into Wednesday. Wednesday's high is expected to hit 28 C.
Temperatures the rest of the week should peak in the low 20s in the capital with a chance of showers.
Research shows heat waves are becoming increasingly extreme as the climate warms.

How residents are coping with scorching temperatures across Simcoe County
The third day of Ontario's heatwave didn't stop pickleball enthusiasts from hitting the courts in Barrie. Debra Schlieker and Mike Peragine are taking precautions during the spiking temperatures all while playing the sport they love. 'It's too hot, let's face it, but we're crazy diehards so we come out regardless,' said Schlieker. Temperatures over the last three days reached mid 30's with the humidex pushing close to 40C degrees. 'In the heat, it's very hot but I don't complain,' said Peragine. 'I have a towel, I have ice water, and I'll play in the heat, that doesn't bother me. Both players taking necessary breaks when it gets too hot. 'Sunscreen, lots of sunscreen. I have water, electrolytes. Could do more,' said Schlieker. While some people enjoy sports in the heat, others have no choice but to work in it. Walter Trump a service mechanic for Sunbelt Rentals said its important to take care of your body in the warm temperatures. 'Drink lots of fluids. I keep my truck running so if it gets too hot, I just get to the truck and get inside,' said Trumpe. 'Once I cool down for about 10, 15 minutes and then come back out.' He added its important to pace yourself when outside. 'If you're at the shop and we're working we just go into the air-conditioned areas and just relax for about ten minutes,' said Trumpe. Strawberries Strawberries growing at Fernwood Farms near Stayner, Ont on June 24, 2025. (CTV News/Luke Simard) At Fernwood Farms near Stayner the hot weather is impacting some seasonal fruits. Strawberry season has already started later than usual and could end early due to the extreme heat. Kevin Ward, one of the owners and operators at Fernwood Farms said the heat can have a dire effect on fruit, especially strawberries. 'When we get into those hot, very hot, humid conditions. It could be very tough on fruit strawberries, especially because they're just so perishable,' said Ward. He added the best time to come and pick them is in the morning hours. 'Once they start ripening, they never stop and they're just so delicate,' said Ward. 'So, when we get these days that are super hot, like yesterday it was like a hairdryer out here and it just scorches the fruit while it's ripening so it's tough.' Residents around Simcoe County can expect a 'yo-yo' summer season with temperatures fluctuating throughout the summer. This will be the flavor, the personality of the summer so expect more of these,' said David Phillips, climatologist for Environment and Climate Change Canada. 'But they may not be as intense as the one we've just gone through, so we've already weathered it and if you survived that, you're probably okay.'

North York condo residents without air conditioning for days amid heat wave
The apartment building at 120 Varna Drive in Toronto is pictured on Tuesday, June 24, 2025. (CTV News) Hossein Nick has been trying to adjust the thermostat in his condo for days, but no luck. 'It happened like three days ago, and since then, we're suffering with this temperature and the high level of humidity,' he told CTV News. The air conditioning stopped working over the weekend at his building at 120 Varna Dr. in North York, which has more than 300 units. That was right at the start of the heat wave, making it hard for his family to cope, especially his two-year-old. North York apartment The apartment building at 120 Varna Drive in Toronto is pictured on Tuesday, June 24, 2025. (CTV News) A heat warning has been in effect in southern Ontario since Sunday as temperatures rose to nearly decade highs. With the humidity, it has felt like it's in the 40s during the day. '[He] was not able to sleep for the last two or three nights. He's just flipping around, flipping around crying and having a terrible time, unfortunately,' Nick explained. 'We never imagined that we're going to have a kind of popsicle offering to our baby in the middle of the night. But I swear to God, this is something we did last night.' The property manager said they started to receive some complaints Saturday night and called their contractor Sunday for an urgent check. 'There's a part in the cooling tower which is called a bearing that runs a shaft that controls one of the fans and makes sure it's stable in place' and 'that part broke off,' said Ismail Pathan. He said the contract ordered the part on Monday and said it would take days to fix, so he's contacting other companies to see if anyone can get it and install it faster. 'Unfortunately, with the heat wave, it exacerbated the situation where if it was running properly, running at not such a high rate, it might have been fine,' he told CTV News. 120 Varna Drive A unit at 120 Varna Drive in Toronto is pictured on Tuesday, June 24, 2025. (CTV News) While a CTV News crew was at the building, a woman brought several fans as a delivery for a resident, and another one walked in carrying a fan he'd purchased for his unit. 'It's been unlivable condition,' he told CTV News, asking we not to share his name, 'I couldn't sleep properly because in my bedroom, since it is facing the sun morning, it was like over 30 degrees.' Pathan said the condo board is considering compensation for residents.
