While highs are forecast to hover around the low 30s, it will feel like 40 degrees or more outside. Minimum temperatures are expected to be in the low to low 20s overnight. Environment Canada says relatively cooler temperatures are expected on Monday. As a result of the heat, the City of Toronto extended the opening hours of seven city pools until 11:45 p.m. Sunday. These are Alex Duff, Giovanni Caboto, McGregor Park, Monarch Park, Parkway Forest, Smithfield Park and Sunnyside / Gus Ryder. In addition to city pools, residents cooled off in Lake Ontario on Sunday. (CBC) Heat warnings have been issued for parts of Canada, including southern Ontario, southern Quebec, New Brunswick, Nova Scotia and Prince Edward Island. Monica Vaswani, a meteorologist with Environment Canada, said the magnitude of the heat wave, while notable, is not unprecedented. “When we have heat events, it’s basically due to warm air advections, or essentially a warm or warm air area moving from the south to the northern parts – the provinces of Canada,” he said “It’s not unusual to see large areas of this warm , moist air mass’. And this likely isn’t the last of the heat wave, at least not for Ontario, Vaswani said. “Some indications suggest that temperatures throughout the rest of August, apart from next week, may be slightly above normal, which would suggest the possibility of additional heat events before the summer is over,” he said. During these extremely hot and humid periods, residents are advised to watch for signs of heat illness such as swelling, cramps, rash, fainting, heat exhaustion and heat stroke.

Summer heat to extend into autumn

Summer-like conditions are likely to persist into the fall season, Vaswani said. “Given the trend we’ve seen over the last couple of years, it seems like our summers generally start a little later and stay at least through September, even mid to late September, so I wouldn’t be surprised if we see something similar this year,” he said. . Heat warnings are issued when high temperatures or humidity levels are expected to pose a risk of illness, such as heat stroke or heat exhaustion. Young children, pregnant women, older adults, people with chronic illnesses or people who work outdoors face the greatest risk, the federal weather service says. Keep your cool with the following tips, she says:

Drink plenty of water even before you feel thirsty. Check on older family members, friends and neighbors. Never leave people or pets inside parked vehicles. Take breaks in cool places if you work outdoors.
