Environment Canada issued a heat warning for Ottawa late afternoon Sunday, with daytime highs through much of the week expected to be between 30 and 35 C. High humidity will make the temperature feel between 40 and 45 C.
There will be "little relief" in the evening hours, with overnight lows expected to be between 18 to 23 C and humidex values expected to make it feel between 26 and 30 C.
Temperatures will peak in Ottawa on Tuesday, with the forecast showing a high of 34 C. Conditions are expected to taper off before the weekend, with the forecast showing the heat dipping back down below 30 C on Friday.
"Extreme heat can affect everyone's health," Environment Canada's says.
"The health risks are greater for older adults, infants and young children, pregnant people, people with physical and/or mental illnesses, and people with disabilities or mobility issues."
Heat warnings have been issued across the province, stretching from Windsor to Ottawa, and northward to Moosonee. Warnings have also been issued in western and southern Quebec, including Gatineau, Montreal and Quebec City.
"It's not a severe weather event that comes and then goes. This has got legs to it. It's a heat dome," Environment Canada's senior climatologist David Phillips told CTV's Jack Richardson on Sunday.
"From a health point of view, the first heat wave is often where we see hospitalizations."
Phillips recommends drinking plenty of water and to stay away from caffeine and alcohol.
Environment Canada says to watch out for the effects of heat illness, including swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.
"Call 911 or your local emergency number immediately if you or someone you are caring for has a high body temperature and are confused, has stopped sweating or becomes unconscious," Environment Canada says.
