Environment Canada has issued warnings about extreme heat in parts of Manitoba, Quebec and Ontario, where humidex values could make it feel like a sweltering 45. Cities like Ottawa and Toronto can expect maximum temperatures of 37 C on Tuesday with humidex values making it feel more like 45. Similar scorching temperatures will be felt across the province, including in cities like Hamilton, London and Windsor.

With heat warnings stretching across most of the province, there will be little respite in northern cities like Thunder Bay and Kenora, where temperatures could reach 35 C and feel like 40 with the humidity on Tuesday. “Today will mark the peak of this heat event,” Environment Canada said in its heat warning. “Take action to protect yourself and others – extreme heat can affect everyone’s health.”

Heat warnings are also in place across northern Manitoba, including communities like Norway House and Flin Flon, where temperatures could reach 29 C. In western Quebec, heat warnings are in effect for areas like Matagami, Wakefield, Rouyn and Gatineau, which could see highs of 37 C and humidex values of 45. Several parts of the Northwest Territories are also under heat warnings, including Fort Simpson and Hay River, where daytime temperatures will near 30 C. Coupled with wildfire activity, the extreme heat is also expected to lead to deteriorated air quality in parts of Manitoba, Ontario and the Northwest Territories.

“Smoke from wildfires is causing poor air quality and reduced visibility,” Environment Canada cautioned. “As smoke levels increase, health risks increase. Limit time outdoors.

Consider reducing or rescheduling outdoor sports, activities and events.” This is a developing news story and will be updated.
