Environment Canada’s warning maps stretch from the southeast corner of Saskatchewan all the way to the western edges of Quebec, displaying vivid shades of flames in yellow and orange – a fitting representation for this week as four provinces endure sweltering temperatures that will feel like the mid-40s C when factoring in humidity.
The southern and central regions of Manitoba and nearly all of Ontario, including Toronto and Ottawa, are currently under heat warnings. The weather agency has cautioned about high humidity levels, risks of heat exhaustion, and in some areas, poor air quality.
Yellow alerts signify dangerous weather that “may cause” disruptions or health issues, while orange alerts indicate that they are “likely to” do so. The orange warnings on Monday extend from just south of Regina eastward through Winnipeg up to the Quebec border.
Temperatures in the 30s are anticipated throughout these warning zones, with a peak expected at 38 C in Thunder Bay, Ont.
Records Broken in Manitoba
The heat is set to reach its highest point today in Saskatchewan, Manitoba, and northwestern Ontario; however, other areas under alert will face even hotter conditions on Tuesday. Records have already been shattered in Manitoba where seven communities hit new temperature highs on Sunday. Portage la Prairie broke a record dating back to World War II with a temperature of 35.7 C.
Environment Canada warns that the upcoming hot and humid conditions could worsen air quality that has recently been affected by wildfire smoke.
The City of Toronto has announced that water stations and cooling spots-like pools, beaches, and splash pads-will be accessible for everyone. Similarly, Winnipeg’s leisure centers and libraries will serve as cooling venues.

Safety Tips
Environment Canada advises keeping an eye out for signs of heat exhaustion such as headaches, dizziness, thirstiness, and fatigue. Anyone exhibiting symptoms of heat stroke should call 911 immediately.
Older adults living alone or others considered at risk should be checked on multiple times each day according to the warning.

Here are some additional tips from Environment Canada:
Drink water frequently-even before you feel thirsty. Close blinds or shades and open windows if it’s cooler outside than inside. If your home feels hot, find a public space like a cooling center or library instead. Schedule outdoor activities during the coolest parts of the day. Wear lightweight clothing that’s light-colored and loose-fitting along with a wide-brimmed hat. Follow guidance from your local public health authority.
