‘It was intense': Heatwave relief in sight this week for Canadians
Some relief is in sight for millions of Canadians after three days of intense heat that saw Toronto experience its hottest day in nine years. The high for many cities in eastern Canada is forecast to be below 30 C on Wednesday, though the humidex will still be in the low 30s.
Looking back on the heat wave that began on Sunday and saw the humidex reach 46.7 C in Toronto, David Philips says what made it particularly notable was the unseasonably cool May and June that preceded it. The senior climatologist with Environment and Climate Change Canada says before Sunday, Toronto had just a single day above 30 C this year, which is unusual.
'And so that really is very late coming,' said Philips, emphasizing the danger posed by the sudden onset of extreme heat. 'It was intense. It was late coming. And also, (it) wasn't just a one-day wonder.'
The Region of Waterloo Paramedic Services has seen an increase in heat-related calls. Jason Dippel told CTV News that heat exhaustion and heat stroke are serious concerns, as they can be life-threatening.
Dippel urged extra caution for vulnerable groups.
'Younger individuals, those experiencing chronic illness, you've got the elderly, all more susceptible to heat exhaustion or heat stroke,' said Dippel.
The intense heat has made daily life challenging for many. A woman in Toronto described the conditions as 'definitely not great.'
'It's hard to be outside and I can't imagine what it's like for people that don't have (air conditioning) at home,' she said.
Residents of a Toronto condo building experienced this difficulty firsthand when their central air conditioning broke down just as temperatures began to climb on Sunday. One resident, who wished not to be identified, purchased a fan but described the conditions in their unit as 'unliveable.'
'I couldn't sleep properly because in my bedroom since it's facing the sun in the morning, it's like over 30 degrees just inside the bedroom,' they told CTV News.
The lack of air conditioning in many Ontario schools, particularly older buildings, has also become a point of contention. Some parents have opted to keep their children home, prioritizing their health and comfort over classroom attendance.
Erica Phipps of the Canadian Partnership for Children's Health and Environment spoek with CTV News, highlighting the risks extreme heat poses to children, including its impact on cognitive function. She argued the current heat wave underscores how ill-equipped educational facilities are for a changing climate.
'It used to be that maybe schools could get away without that infrastructure (air conditioning), but that is no longer the case,' said Phipps.
Earlier this year, Phipps's group, along with 40 other organizations, advocated for a maximum indoor school temperature of 26 C to protect children. She also suggested immediate measures such as window coverings and fans.
'Scientists are finding that extreme heat, or even prolonged elevated temperatures, affect brain function,' she said. 'They affect memory and cognition, and can also contribute to other issues that kids may be struggling with, irritability and frustration.'

Storms clobber southern Manitoba with piles of hail and brilliant lightning display
Hail and thunder pounded parts of southern Manitoba and forked lightning flashed in the sky like "disco lights" as a series of summer storms roared through Wednesday overnight into Thursday. "Many people in the city are probably groggy-eyed waking up this morning, talking about [their lack of sleep]. We definitely had a lot of rain last night, hours and hours of lightning and thunder," said Environment Canada meteorologist Crawford Luke. "These storms basically just kept reforming and reforming and reforming basically between Winnipeg and Portage [la Prairie]." Rainfall totals in Winnipeg ranged from 15 millimetres on the east side of the city to nearly 60 mm on the west side. The greatest amounts were recorded around the Portage la Prairie area, with that city and nearby High Bluff both getting 101 mm. "It's basically like more than a month's worth of rain — almost two months' worth of rain — falling overnight," Luke said. Further south, toward the international border, the totals drop off to about one or two millimetres, except for some locations southeast of Winnipeg, where 32-75 mm were recorded. That data comes from the Community Collaborative Rain, Hail and Snow Network, CoCoRahs, a network of citizen volunteers who measure weather data, from which Environment Canada gathers reports. High Bluff — 101 mm. Portage la Prairie — 101 mm. Poplar Point — 98 mm. Sanford — 94.2 mm. Starbuck — 91.2 mm. Zhoda — 74.6 mm. Elie — 72.4 mm. Brunkild — 66.2 mm. St. Norbert — 49 mm. Steinbach — 41.5 mm. Winnipeg (Westwood) — 58.7 mm. Winnipeg (Whyte Ridge) — 49.5 mm. Winnipeg (St. James) — 31 mm. Winnipeg (downtown) — 30 mm. Winnipeg (Transcona) — 15 mm. "We also have numerous reports of loonie-sized hail, toonie-sized hail, even some golf ball-sized hail … two-, three-, four-, five-centimetre-diameter hail, so quite sizeable — certainly capable of denting cars and causing other damage like that," Luke said. Dawn Kautz Nee Bohncke, who was scooping up handfuls of hailstones off her property in Kleefeld, south of Winnipeg, said her squash and pumpkin leaves are in tatters, and there are definite dents on the family vehicles. In a Facebook post, Kautz Nee Bohncke described the storm as "disco lights" and said her area was "hammered with the loudest and longest hail I've experienced." So far, Environment Canada hasn't received any reports of tornadoes or even funnel clouds, Luke said. "But reports could be trickling in throughout the day. We might learn something later," he said. "Right now it looks like just a bunch of hail reports and a lot of rain." The stormy weather began forming around 9:30-10 p.m. and kept rolling through to about 6 a.m., Luke said. "Just going through the radar even right now, it's really impressive. We call this back building or training … when thunderstorms kind of reform over the same area over and over again." Those are the types of storms that lead to flash flooding, though no reports of that have come in, Luke said. There were a number of power outages reported by Manitoba Hydro across the path of the storms, but crews were expected to have things back on by noon Thursday, a spokeserson said.

Post-exposure vaccines recommended to children following rabid bat in Brantford daycare
Grand Erie Public Health (GEPH) has recommended post-exposure vaccines to all kids that attended a Brantford daycare before Aug. 14. A dead bat, found in a 3rd floor pre-school room in the Creative Minds daycare on Aug. 11, had tested positive for rabies, with results coming back two days later. It had been handled by one child and one staff member. Since then, the daycare has worked alongside Grand Erie Public Health (GEPH) to address the issue. GEPH sent an email to daycare parents on Tuesday and stated that, though their review did not find any additional adults or children made contact with the bat, they were offering any children who attended the daycare before Aug. 14 post-exposure prophylaxis (PEP) vaccines. 'Rabies is a very serious disease but it is preventable with timely PEP. We are recommending this vaccine series out of an abundance of caution, to ensure all children remain protected,' the email said. The full PEP vaccine series includes a total of four doses of the rabies vaccine with one initial dose of rabies immune globulin. The series is given over a two-week period. GEPH hosted a clinic for the first PEP dose at Lynden Park Mall on Wednesday. GEPH told CTV News in an email they have three more vaccine clinics scheduled as of Thursday: Saturday, Aug. 23 from 9:30 a.m. to 5:30 p.m. Wednesday, Aug. 27 from 2 p.m. to 7 p.m. Wednesday, Sept. 3 from 2 to 7 p.m. Anyone with questions has been asked to call GEPH at 519-900-9600 ext. 3214. Daycare closure The dead bat was not the only animal found at the centre. The daycare confirmed a live bat was also found in a stairwell on Aug. 12. The daycare said that the bat did not have contact with any children or staff members and was captured and released. The centre said the live bat was found on the second floor but came into a hallway from a classroom storage room. The centre closed on order of GEPH on Aug. 13. for pest control measures and thorough sanitation. GEPH 's temporary closure order has since been lifted.
