The number of people who have died due to heat-related complications has increased from yesterday's 17 to 33, around Quebec, according to Public Health officials.
"We really hope that the next information we have to give out is the last and total number of deaths for this heat wave".
While the stifling weather also hung over Ontario and parts of Atlantic Canada, no deaths had been reported elsewhere, in part because various jurisdictions have different ways of gathering data on heat-related fatalities.
While hot weather is expected to remain in Quebec next week, Serge Mainville of Environment Canada said it will be a dry heat.
While temperatures have come down on Friday, public health officials are warning that the Quebec residents should still take precautions in the wake of a week-long heatwave that claimed at least 44 lives throughout the province.
Six boys have been rescued from flooded cave in Thailand
Officials were concerned that monsoon rains, which were forecast for today, would make such a rescue essentially impossible. Several of the boys emerged from the cave on Sunday , about eight hours after 18 divers began their operation to free them.
A young boy plays at a water fountain in 2010, when a high heat and humidity warning like the one in place now was in effect for several regions in Canada.
The other victims were reported in the southwest of the French-Canadian province, the Quebec health ministry said. "The elderly, people with chronic diseases and people with mental health problems are more at risk".
She added that they were living in "vulnerable conditions" and without access to air conditioning.
Meanwhile, a risky heat wave is expected to grip California and parts of the southwest Friday and into the weekend, threatening millions of people and likely fueling existing wildfires in the United States.
