Environment Canada has issued a series of heat warnings stretching from southeastern Saskatchewan to the western border of Quebec, as four provinces face extreme temperatures that will feel like the mid-40s C with humidity. The weather agency identifies this as a hazardous event, with orange alerts indicating that health impacts are likely, and yellow alerts signaling that disruptions or health issues may occur.
Did You Know? In Portage la Prairie, Manitoba, the temperature reached 35.7 C on Sunday, surpassing a previous record set during the Second World War.
Regional Heat Peaks and Record Temperatures
The heat is expected to peak today across Saskatchewan, Manitoba, and northwestern Ontario, while residents in other affected regions, including Toronto and Ottawa, should prepare for higher temperatures on Tuesday. Sunday saw seven communities in Manitoba establish new record highs. Environment Canada warns that the combination of high humidity and heat could lead to a deterioration in air quality, which has already been impacted by recent wildfire smoke.
Municipalities are responding to the extreme conditions by opening cooling stations to the public. In Toronto, the city has made pools, beaches, splash pads, and water and cooling stations available. Similarly, Winnipeg is offering access to its libraries and leisure centres as designated cooling areas. Officials recommend that residents check online resources to locate the nearest cooling centre in their specific region.
Environment Canada advises that individuals should monitor for symptoms of heat exhaustion, such as dizziness, thirst, fatigue, and headaches. If an individual shows signs of heat stroke, the agency stresses that 911 should be called immediately. Residents are encouraged to check on older adults and those living alone multiple times throughout the day to ensure their safety.
Strategies for Heat Mitigation
To reduce the risk of heat-related illness, the public is encouraged to follow several safety guidelines:
- Drink water frequently, even before feeling thirsty.
- Keep blinds or shades closed to block sunlight and open windows only when the outside air is cooler than the indoor temperature.
- Move to a shaded park, library, or community centre if living spaces remain too hot.
- Schedule outdoor activities for the coolest times of the day.
- Wear lightweight, loose-fitting, light-coloured clothing and a wide-brimmed hat.
