Heat wave in parts of Ontario, Quebec expected to last until Monday: meteorologist

Social Sharing Hot, humid weather settled over much of Ontario and parts of Quebec on Saturday with Environment Canada warning of a multi-day heat wave set to bring even higher temperatures Sunday and Monday. Environment Canada said several days of sweltering conditions began taking hold of southern Ontario and half of northeast Ontario on Saturday, blanketing communities including Windsor, Timmins, Sudbury, Toronto and Ottawa. A severe weather meteorologist with the federal agency said the wave extended across the provincial border with Quebec to encompass regions including Montreal, pushing daytime highs to 35 C in southern areas and 33 C in the north, with the humidex at or near 40 C. Weiqing Zhang warned that Saturday was just the beginning of uncomfortably warm weather. "The hottest day will be tomorrow — Sunday — and then Monday," Zhang said. Some relief may come Monday for northern areas, Zhang added, but southern regions stretching from the Ottawa area all the way to Windsor could see high temperatures lasting into Tuesday. GTA under 6th heat warning this year Parts of Newfoundland and Labrador also received heat warnings Saturday, with near 30-degree temperatures expected in areas including St. John's and Gander. Zhang said the criteria for heat warnings in the Atlantic province is slightly lower than those for Ontario and Quebec. Zhang said the Greater Toronto Area has had a particularly hot year, noting the current heat warning marked the region's sixth for 2025. That's compared to four warnings issued in 2024, a benchmark she said the GTA reached this past July. WATCH | Some Torontonians have struggled to stay cool during earlier heat waves this summer: 'Unliveable conditions': Why it's impossible to stay cool for these Toronto residents 2 months ago As the GTA's heat wave rages on, some residents have been struggling to stay cool. CBC's Dale Manucdoc speaks to Torontonians living in buildings without air conditioning and those who have no choice but to work outside. She expected another heat warning could be issued later in August. "I can't guarantee it but based on the current guidance it looks like at least in late August we'll probably have another one — the week of Aug. 20," said Zhang. "This year the whole, the big weather pattern is favourable for hot and humid conditions." The current heat bout will offer slightly cooler nights but it will still be warm, she added, with overnight temperatures expected to linger in the 20s. Zhang advised people to limit direct exposure to the sun and heat, if possible, with any outdoor activities scheduled during the coolest parts of the day. The weather agency warned the heat wave could pose health risks and says to watch for signs of heat exhaustion, including headache, nausea and dizziness.

‘Multi-day' heat event begins as temperatures set to hit 35 C in Ottawa this weekend

A tourist carries an umbrella as they visit Parliament Hill in Ottawa on Tuesday, June 18, 2024. THE CANADIAN PRESS/Sean Kilpatrick Officials are urging caution as another multi-day heat event is set to bake the nation's capital this weekend. Environment Canada issued a heat warning for Ottawa starting today, forecasting highs to be between 30 and 35 C with humidex values of 35 to 40 stretching into early next week. Overnight lows won't provide much relief as temperatures stay between 19 to 22 C. Slightly cooler temperatures are expected by mid-week, bringing an end to the heat event, Environment Canada says. The average daily high for this time of year is around 26 C, with lows around 15 C. Health Canada recommends staying cool and staying hydrated when extreme heat hits. Watch for symptoms of heat stroke, including dizziness, nausea, confusion and change in consciousness. Anyone showing signs of heat stroke should call 911. Ottawa weather Saturday's forecast shows a mix of sun and clouds with a 30 per cent chance of showers and a risk of a thunderstorm. Hazy skies from wildfire smoke remain over the capital. The air quality for Ottawa was 4, or moderate, at 11 a.m. Saturday. Tonight will be partly cloudy with a 30 per cent chance of showers early this evening with a risk of a thunderstorm. Hazy this evening. Low 21 C. Sunday will be mainly sunny with hazy skies in the afternoon. High 35 C with humidex levels expected to make it feel like 42. It's a similar story on Monday with a high of 35 C. Tuesday will be sunny with a high of 34 C. Some relief from the heat isn't expected until Wednesday as the high reaches 28 C.
