Multiple heat and air quality advisories are in place across Canada
This is in addition to a number of air quality advisories issued to several parts of the country as a result of wildfire smoke.
The heat warnings cover southern Ontario, Greater Montreal and some surrounding areas, central and northeastern Newfoundland, and the Annapolis Valley in Nova Scotia, though the alert is expected to expand to the mainland of the province.
In Ontario, expect hot and humid conditions to last through much of this week, with daytime highs between 29 and 32 C. Parts of Quebec, including Greater Montreal, Lachute, Lanaudière, Montérégie and Drummondville, will experience daytime highs of up to 33 C, which combined with high humidity will feel closer to 40.
Central and northeastern Newfoundland, including Clarenville and vicinity and the Bonavista Peninsula, will experience temperatures up to 32 C, with a humidex of up to 37, while hot, dry weather will continue in Norman Bay - Lodge Bay, with daytime highs between 27 and 30 C.
In Nova Scotia, the heat and humidity is expected to last until Thursday, with daytime highs of up to 33 C, which could feel like up to 37 with humidity.
Air quality advisories
Air quality advisories have also been issued for eastern parts of Alberta, as well as some regions of the Yukon, Saskatchewan, Manitoba, Quebec and Ontario as a result of wildfire smoke.
As winds turn northernly, more of central Saskatchewan will be directly in the path of wildfire smoke.
In Ontario, poor air quality and reduced visibility could continue through to Tuesday.
Environment Canada warns people in those area of an increased risk to their health.
'People more likely to be affected by wildfire smoke, including people aged 65 and older, pregnant women, infants and young children, people with an existing illness or chronic health condition, and people who work outdoors, should avoid strenuous activities outdoors and seek medical attention if experiencing symptoms,' Environment Canada cautioned.

Borden pool now open after delay caused by leak
Borden Natural Swimming Pool is expected to open today, weeks later than normal because of a leak found in June. Borden Natural Swimming Pool opened for the summer on Tuesday. The pool was supposed to open on June 21 before a leak in one of the pool basins – believed to be caused by the freeze-thaw cycle – was found. Arthur Robinson, Borden pool's facility lead, told CTV News Edmonton 'it means a lot' to finally be open. 'Especially having the staff getting ready to work out here and then having our season in question a little bit,' he said. 'But I'm glad that we are able to open with the work that was done.' Repairs were estimated to cost between $80,000 and $100,000.

More communities evacuate as crews continue to battle wildfires in northern Sask.
More communities have been ordered to evacuate as crews continue to battle wildfires in northern Saskatchewan. As of Tuesday morning, 11 communities were under an evacuation order, compared to eight on Monday. Evacuated communities include Canoe Lake / Canoe Narrows, the northern hamlets of Cole Bay and Jans Bay, the Resort Subdivisions of Lac la Plonge and Little Amyot Lake, the northern villages of Beauval and Pinehouse, as well as Île-à-la-Crosse, Montreal Lake Cree Nation, La Plonge Indian Reserve, and Patuanak / English River First Nation. According to the Saskatchewan Public Safety Agency (SPSA), there are 50 active wildfires, with two categorized as contained and 16 uncontained, as of Tuesday afternoon. Before the Town of Île-à-la-Crosse was ordered to evacuate, some residents were forced to leave due to air quality concerns on Monday, with the community under a voluntary evacuation order. A total of 385 wildfires have been recorded since the beginning of the year, compared to 407 fires in the same period in 2024. The five-year average to date is 312. A fire ban, which encompasses the area north of the provincial forest boundary up to the Churchill River, is still in place due to an extreme fire risk. According to the SPSA the ban prohibits any open fires, controlled burns, and fireworks. The SPSA advises the public to be prepared to evacuate in the event of an evacuation order for their community. People are advised to keep their vehicle fueled, be set to evacuate pets or livestock if needed, and check in on their neighbours.

Researchers chase storms, study fist-sized stones in Alberta's 'Hailstorm Alley'
Social Sharing Julian Brimelow holds up a replica of the mother of all hailstones — a lumpy white blob as big as your fist carrying the weight of two baseballs with the power to pulverize fields of corn into green-yellow mush. Brimelow and other researchers from Western University in London, Ont., are using it in their research to better understand and predict Alberta's prevalent hailstorm activity, and mitigate harm to people and property. Hail can be bad across the Prairies. But Brimelow says when it hits in Alberta, it hits hard. "It's much worse than I thought it could be in terms of damage potential," Brimelow said Tuesday at the project's open house at the Telus Spark Science Centre. "On the same day as the (2024) Calgary hailstorm, there was a storm farther south and that decimated six to seven-foot corn crops to the point that our team wasn't sure it was actually corn," he said. "It was that pummeled into the ground." WATCH | The Northern Hail Project surveys the damage caused by Calgary's recent hailstorm How a Canadian storm laboratory is investigating Calgary's hail damage 4 days ago The Canadian Severe Storms Laboratory at Western University in London, Ont., has dispatched a damage survey team to chase and investigate destruction from Alberta storms this summer. The 'Northern Hail Project' crew went out with the CBC's Acton Clarkin after a major hailstorm hit pockets of Calgary. "Hailstorm Alley" runs from High River, just south of Calgary, north to central Alberta. The area sees more than 40 hailstorms every summer, causing hundreds of millions of dollars in damage. Brimelow, executive director of the Northern Hail Project — a branch of Western University's Canadian Severe Storms Laboratory — said it's probably the most active hailstorm zone in Canada. A storm in Calgary last August brought significant hail, strong winds, heavy rain and localized flooding, affecting about one in five homes. The Insurance Bureau of Canada estimated the damage to the city, deemed the country's second-costliest weather-related disaster, at $2.8 billion. Hailstones as big as golf balls hammered the tarmac at Calgary International Airport, damaging planes at WestJet and Flair Airlines, and forcing them to ground 10 per cent of their fleets for repairs and inspections. Brimelow said such hailstorms are underestimated at one's peril. Several small animals and pets were killed in Calgary last year, he said, and an infant was killed in Europe in 2023. The research sees stones collected on scene, preserved in a mobile freezer, and later measured, weighed, photographed and perhaps replicated. "The more interesting stones we'll 3D scan and then we can make prints," he said. Copies of several realistic hailstones were on display at the open house, ranging in size from a walnut to a golf ball and one bigger than a large hand. "This is the new record-sized Canadian stone. This fell in 2022 near Innisfail," Brimelow said. "This is 12.3 centimetres across and nearly weighs 300 grams. This would have been falling at 160-plus kilometres an hour." The team's field co-ordinator, Jack Hamilton, said the size and shape of the stones provide researchers with information on what happens inside the storms. "It was long thought that the hailstone sort of goes through the storm in a washing machine cycle. But we're actually learning that it's probably just once, maybe twice, that the hailstone goes through the storm and it collects all of its mass in that one travel through," Hamilton said. "It gets bigger and bigger, and eventually gravity takes over and it falls. And it falls pretty fast." To get the stones, they first have to chase them. Hamilton said their chase vehicles have a protective coating against hail and are equipped with storm-locating radar and a lightning detector for safety.
