‘Heat dome’ over Ontario and Quebec causing wild weather across much of Canada

Blame the heat dome hanging over Ontario and Quebec for some of the strange weather hitting other parts of the country.
Environment Canada meteorologist Julien Pellerin says scorching temperatures over the eastern part of the continent are causing below-normal temperatures in other regions, which have led to warnings of wet snow and heavy rain in the West.
“If you have a heat dome on a sector, you can expect colder air in another sector, so that’s what the Prairies are currently experiencing,” Pellerin said on Sunday.
“It’s coming from the United States, a high-pressure system that doesn’t move quickly … so it brings intense heat and moist air over southern Ontario and southern Quebec and it’ll settle there for the next three days.”
The dangerous temperature levels span from southwestern Ontario towards North Bay, Sudbury and Timmins, while in Quebec the highest temperatures are expected from Montreal to Shawinigan and north up to Abitibi.
Pellerin says he expects Ontario and Quebec to hit their peak daytime highs on Monday and Tuesday with temperatures rising above 30 C, and the humidex making it feel more like 40 to 45 degrees, depending on the region.

“It won’t last very long,” he added. “By the end of Tuesday and Wednesday, we will have a transition in air mass all over Canada, especially over Quebec and Ontario.”
In the meantime, the effects of the heat dome are bringing surprises to other parts of the country.
On Saturday, Environment Canada warned that areas in British Columbia could face heavy showers, and over some of the highway summits, the possibility of wet snow.
Meanwhile, heavy rainfall advisories that had been in effect in southern Alberta were all lifted by Sunday, but the region received significant precipitation. City residents were being warned to stay off the Bow River.
The Calgary Fire Department advised against boating and all other water activities on the Bow due to higher-than-normal water flow, although the city said flooding over riverbanks was not expected.
“We know that Calgarians love their rivers, yet we also know that when our waterways flow this high and fast, there’s significant risk to anyone, regardless of your watercraft or skill level,” Calgary Fire Deputy Chief Pete Steenaerts said in a news release.
Saskatchewan’s Water Security Agency warned the Alberta rain could also lead to increased flows on the South Saskatchewan River between the Alberta boundary and Lake Diefenbaker.
The agency said Alberta began dumping water from reservoirs this past week to make room for the additional run-off.
It expected lake levels at Lake Diefenbaker, a large reservoir northwest of Regina that’s a popular recreation area, to rise over a metre this week as a result of the weather system.
Heat levels in Ontario and Quebec led Environment Canada to remind people to stay hydrated by drinking water before they’re thirsty, to watch for early signs of heat exhaustion and not overexert themselves.
“Be careful; you know yourself,” Pellerin said.
“Make sure you’re aware of what you’re feeling and take breaks, Make sure you have a location where you can rest with the air conditioning.”
In Quebec, schools are being urged to stay vigilant with the rising temperatures.
In a letter from the assistant deputy education minister, schools were encouraged to “put in place all the preventative measures you judge necessary to ensure everyone’s security.”
“Depending on the situation, these measures could go all the way up to closing one or more schools for the day of June 23,” said the message signed by Stephanie Vachon.

A new poll by Leger has found that Quebec residents are the happiest in Canada.
The web survey of nearly 40,000 Canadians found that Quebecers rated their happiness at an average of 72.4 out of 100, which is well above the national average.
New Brunswick followed Quebec with an average of 70.2, while Manitoba and Prince Edward Island finished at the bottom of the list.
Mississauga, Ont. had the highest happiness rating of the 10 largest cities, while Toronto was lowest.
Montreal finished second in the category.
The survey found that 49 per cent of respondents said their happiness level was unchanged over the past year, while 23 per said they were happier and 28 per cent said they were less happy.
“These results reveal a population that is both resilient and tested, affected by everyday uncertainty and challenges,” Leger’s executive summary read. “Happiness, while holding its ground overall, shows signs of fragility.”

The survey found that people in the 18-to-24 and 24-to-34-year-old categories were more likely to report improved feelings of well-being, even if their overall happiness score remained below the national average.
In contrast, people in the 35-to-44 and 45-to-54 age brackets were more likely to report their happiness had deteriorated.
“There is a sense of well-being emerging among younger age groups,” the summary read. “However, this also highlights the importance of supporting adults in mid-life, who are more vulnerable to the pressures of working life.”
Quebec, New Brunswick and Newfoundland and Labrador were the three provinces with happiness levels above the national average of 68.7. They were followed, in descending order, by Saskatchewan, Nova Scotia, Alberta, British Columbia, Ontario, Manitoba and P.E.I. The territories were not included in the survey.
In the survey of the 10 largest cities, Mississauga and Montreal finished ahead of Hamilton, Calgary, Brampton, Ottawa, Edmonton, Vancouver, Winnipeg and Toronto, in that order.
Women reported slightly higher happiness levels than men, at 69.4 versus 68.0.
Leger says the overall results confirm “a level of happiness that is relatively high but stagnant or even slightly down compared to the pre-pandemic period.”
To get the results, Leger surveyed 39,841 Canadians aged 18 and up between March 31 and April 13.
Online surveys cannot be assigned a margin of error because they do not randomly sample the population.

Ontario Provincial Police are set to host a town hall in Quadeville, Ont., this evening to answer questions from residents about an attack on an eight-year-old child that was initially linked to an animal.
Police have arrested a 17-year-old boy in the case and he faces charges of attempted murder and sexual assault with a weapon.
Members of the small community 170 kilometres west of Ottawa say they were in shock after hearing about the arrest and hope to get clarity at today’s event in the town’s community centre.
Local resident Christine Hudder says she wants to know how police came up with the animal attack theory and why families were told for days to keep their children indoors.

The victim was found with life-threatening injuries on June 24 after she was reported missing, and remains in hospital.
Police say they are planning to give as much information as possible to locals given that an investigation is still underway.

A Burlington, Ont., mother was unsettled to discover that an old photo of her children had been used in a fraudulent GoFundMe that attempted to elicit donations in connection the recent Texas floods.
Julie Cole told Global News that a friend had contacted her on social media to say that an old photo of her six children was being used in an attempt to collect ill-gotten gains.
“She reached out to me and she was like, ‘Hey, here’s a link to a GoFundMe. Sorry this has happened to you, but obviously a picture of your kids has been used without your consent and it’s being used for a GoFundMe to raise money, to help a family dealing with the Texas floods,’” she said.
Cole explained that the fake GoFundMe, which has since been removed by the company, was looking for donations to support a widowed mother of six kids in connection.
At least 120 people have died while more than 100 others remain unaccounted for as a result of the flooding, including 27 children and councilors from Camp Mystic.
“They were trying to raise $40,000 because of the three daughters had been victims of the Texas floods,” Cole said. “And the way it was presented felt very much like they were part of maybe that girl’s camp.”
Julie Cole told Global News that a friend had contacted her on social media to make that an old photo of her six children was being used in an attempt to collect ill-gotten gains.

Cole said once the listing was sent to her, she immediately contacted GoFundMe to get the fundraiser taken down.

By Wednesday morning, the company had done so and in a statement to Global News, GoFundMe said that the fundraiser did not receive any donations and the account has been banned from creating any further fundraisers on the platform.
“GoFundMe has the most robust donor protection processes of any platform of our kind. We have round the clock trust and safety support, humans and technology making sure funds will get to where they are intended,” the statement offered.
After contacting the company, Cole said she shared the incident on her social media pages to raise awareness.
“So I did put it on my Facebook and I put it in my LinkedIn as like a heads-up learning experience kind of thing and there was a lot of outrage,” she said.
Cole also noted that while she is disappointed by the incident, she is well aware that her troubles are miniscule in comparison to those affected by the flooding.
“I do feel a little bit in myself that what I’m feeling is in no way comparable to what the actual families are feeling who have gone through the tragedies of the flooding,” she said.
The photo came from an old blog post she had written 16 years ago. Cole can date the picture as the baby in the photo is now getting ready to go for his driver’s test.
“I’m one of those, like, OG mommy bloggers from 20 years ago. So my kids have been on the internet. They have been sort of in the public eye,” she explained.
“And I know the risk is out there. And I think parents need to remember that, that their kids’ photos can be just screenshotted and used without consent. So there’s one lesson.
“I felt a little, well, very unsettled about it, particularly because of what it was being used for.”
In addition to being a parenting blogger, she also helped found Mabel’s Labels, which offers washable labels for kids clothing and other school items, in an effort to keep them out of the lost and found.

Being a spokesperson for the company while raising six kids keeps her in the parenting sphere and she offered some other advice to parents about the images and social media.
“I think parents just have to be mindful and aware that once it’s out there, you know you’d like to think you’ll get consent or you’ll give consent if somebody asks or they want to use it, but people will just take it and they can just take,” she said.
“You have to be especially careful now with AI, because these photos can be altered.”
She also warned parents to check with their kids as they get older to see if they are OK with pics being posted and that people should be mindful of where they are sharing their donations.
“Another lesson out of this is people need to really be cautious and know where they’re putting their fundraising dollars,” Cole said.
