More people died across the greater Montreal area over the last few days than normal, though public health officials are not yet ready to blame the weather.
On average, 40 die each day in Montreal.
On July 7th, there were 43 deaths, and 80 on July 8th.
In a Friday news conference, Luc Lefebvre, of Montreal's Public Health Agency said high heat and humidity could be to blame, but it was still too soon to confirm anything.
Even though temperatures began to go down Friday afternoon, following the rain and thunderstorms, Montreal public security officials say they will continue to operate according to the emergency heat plan instituted across the city.
The heat finally gave way to violent thunder storms Friday afternoon, but not before the humidex factor reached a steamy 40 degrees Celsius.
As is frequently the case during major downpours, there were traffic problems caused by the storms.
A number of cars got stuck on roadways when they tried to drive through flooded areas.
Some of those included parts of Highway 40 around Acadie, Highway 15 at Salaberry, and even parts of St-Laurent Street.
Storms also caused a number of power outages Friday afternoon, leaving some 49-thousand Hydro Quebec clients without electricity across Quebec.
Environment Canada is warning of another heat wave for southern Quebec next week, with temperatures expected to climb back over the 30 degree mark, feeling like 40 degrees with the humidity.
