Heat, thunderstorm and air quality alerts: What's in store for Canadians this weekend
Residents of Quebec and Manitoba can expect a sweltering start to the weekend as Environment Canada warns of extreme heat and humidity in parts of the country.
The weather advisory posted on Saturday says southern Quebec can expect temperatures over 30 C and a humidex of around 40 from Sunday afternoon through Tuesday.
'It will be particularly uncomfortable at night,' the weather advisory warns, with temperatures remaining higher than 20 C.
Areas in southern Manitoba are under a similar warning for Saturday, with humidex values of around 38 in the afternoon.
'Conditions are expected to improve with the passage of a cold front overnight Saturday night,' Environment Canada says.
Health Canada has issued an advisory for how to protect yourself from the health effects of extreme heat.
Meanwhile, warnings of severe thunderstorms 'capable of producing nickel to ping pong ball size hail' have been issued for parts of Ontario.
The weather advisory also warns of winds gusting 90 km/hand heavy rains.
Impacted areas include Cat Lake, Casummit Lake, Birch Lake, Whitestone Lake, Kapikik Lake, Gitche Lake, Maxim Lake, McCoy Lake, Nikip Lake and Senia Lake.
Air Quality Warnings
Environment Canada continues to issue air quality warnings for regions in Manitoba, Ontario, Quebec, Saskatchewan and the Northwest Territories.
Wildfire smoke is causing poor air quality and reduced visibility in these areas through the weekend, the weather alert says.
'Air quality and visibility due to wildfire smoke can fluctuate over short distances and can vary considerably from hour to hour,' it reads.
Residents are advised to avoid outdoor activities, reschedule or cancel outdoor events, keep their doors and windows closed and use a respirator-type mask like a NIOSH-certified N95 or equivalent to reduce exposure to smoke.

Bay and Algoma Buskers Festival marks 10th year
While some intense weather caused some concern over the weekend, the 2025 Bay and Algoma Buskers Festival was a success, organizers said. The 10th annual festival ran Saturday and Sunday in the Bay and Algoma neighbourhood. It featured various food and merchandise vendors, and performers from Thunder Bay, and around the world, including: Steve Goodtime Seb and Fritzzz Fraser Hooper Skye the Guy Kasmir the Hungry The Kidd Creed Statuary Women in Silk Taiko Drummers Phineas Gauge, and the Bay Street Bastards. Things got underway later than planned on Sunday, due to a heavy downpour that hit the city late in the morning, said Uriel Lubuk, one of the event's coordinators. "It was awesome to see a lot of the arts and culture community come out," he said. "Awesome vendors, lots of smiley faces, lots of kids." "We've always wanted free family fun," Lubuk said. "People come down, tip the buskers, see something new and amazing that they haven't seen before." One of the local buskers was Zachary Ross, who performed both Saturday and Sunday. "I've started learning how to do folk music," he said. "I host open mics at Lakehead Beer Company, and yeah, just love the community and love going out to play." "I think it's a great time," he said of the festival. "I love seeing everyone out here." Lubuk said organizers are already turning their attention to next year's buskers festival "and just seeing how we could push through, do a little bit better next year, but just keep the vibes the same."
