Atlantic Canada sees more sweltering temperatures, relief expected in Ontario
People escape the heat and humidity at Cherry Beach in Toronto, Tuesday, Aug. 27, 2024. THE CANADIAN PRESS/Paige Taylor White Extreme heat is expected to ease in many parts of Canada today, while the Atlantic provinces continue to bear the brunt of a multi-day heat wave. Relief is expected in southern and eastern Ontario, but Environment Canada says temperatures are still above average for this time of year, with forecasted highs in the low 30s. The national weather agency says conditions will begin to improve today in many parts of Quebec, with more seasonal daytime highs and lower humidity expected by Thursday. Meanwhile, New Brunswick, Nova Scotia and Prince Edward Island will continue to see daytime highs reaching the mid to high 30s, with humidity making it feel closer to 40. In Newfoundland and Labrador, Environment Canada says extreme heat with humidex values in the 40s is expected to continue until Thursday, with some areas remaining warn enough to warrant a heat warning until Friday. The national weather agency advises people to limit the amount of time they spend outside, to drink water and to watch for early signs of heat exhaustion. This report by The Canadian Press was first published Aug. 13, 2025.

Northwestern Ontario's 1st tornado of the year confirmed by Western University researchers
Northwestern Ontario's first tornado of the year has been confirmed by researchers at Western University, reaching maximum wind speeds of 190 kilometres an hour and creating a nearly six kilometre-long path of damage. The EF2 tornado touched down near Law Lake northeast of Mine Centre on July 27. Environment and Climate Change Canada had issued several severe thunderstorm and tornado warnings for the region that day. "There [were] a number of intense storms that day, and this tornado spawned from a supercell thunderstorm — so that's a thunderstorm where the whole updraft, the storm, is rotating on a scale that's larger than the tornado," said Dave Sills, director of the Northern Tornadoes Project at Western. Of the eight EF2 tornadoes confirmed in Ontario last year, seven occurred in northwestern Ontario. There were no tornadoes rated higher than EF2 in the province. It can take researchers longer to confirm tornadoes in more remote areas, as opposed to places near roads and railways where teams can collect ground imagery themselves using drones, he explained. In this case, his crew relied on satellite imagery, which can be challenging. "Between forest fire smoke and the cloudy days, sometimes you have to wait a while to get a really clear day to compare the before and after shots of a certain area," said Sills. "We're still waiting for clear satellite imagery [for] a few different events, so there may be a couple more additions to the tornado list up in northwestern Ontario based on our satellite analysis." 'Know the risks' The Northern Tornadoes Project dates back to 2017. Last fall, it became part of the broader Canadian Severe Storms Laboratory, a partnership between Western University and ImpactWX, which also includes the Northern Hail Project and Northern Mesonet Project. "We'll be looking at building climatologies for all these things, so that we know the risks," said Sills. The project's initial purpose was to help bridge the gaps in data on tornadoes in Canada's northern communities, where storm systems can be harder to track. "That's one of the things we set out to do right from the beginning is try to document better the tornadoes that happen away from population centres," Sills said. "We've documented hundreds of tornadoes in the boreal forest that we didn't know about before, both on a year to year basis as we move forward from 2017 when the project started, but also going back to the '80s." That's one of the things we set out to do right from the beginning is try to document better the tornadoes that happen away from population centres. - Dave Sills, director of the Northern Tornadoes Project The Northern Tornadoes Project offers OpenData on its website, so anyone can access information about extreme weather events across the country. The overarching goal is to provide people with the tools they need to better prepare for emergency situations, said Sills. "For risk assessment by municipalities, by governments, by industry, it's really necessary to have a really robust climatology of tornadoes and other wind types across the country," he said. There have been a number of tornado watches and more severe warnings issued in northwestern Ontario this summer. People are encouraged to report possible tornadoes and other severe storms to ONstorm@ They can provide information to the Northern Tornadoes Project directly at ntp@ or through its online form, and can also share photos or videos on social media using #ONStorm. "When there is a threat of high winds, as in the case of a severe thunderstorm or tornado, your first priority is to take shelter. If it is safe to do so, bring livestock and/or pets indoors, close all windows and doors, and secure loose outdoor objects or move them inside," Environment and Climate Change Canada says on its website. "Go to the basement or to a small interior room in the centre of the house, such as a closet, bathroom or hallway, on the lowest floor of the building," it says. "Stay away from all windows, doors and exterior walls, in particular those facing the storm." Those boating or swimming should head for land immediately, and those in a vehicle during a tornado should take cover in a low-lying area, such as a ditch, and lie flat.
