The weather agency says a "very warm and humid air mass" has settled over the Maritimes and above normal temperatures and humid conditions will stick around into Thursday. Temperatures in Montreal reached 93 degrees Fahrenheit Wednesday, and are expected to stay the same Thursday.
The extreme weather is already thought to have resulted in almost half a dozen heat-related deaths across the US, and officials in the Canadian province of Montreal linked it to the deaths of at least 15 people.
Montreal health officials say 11 people have died since the intense heat set in over the weekend, with health authorities in the Eastern Townships region east of Montreal attributing another four deaths to the sweltering temperatures. Inland communities are hit harder than those along the coast. Mayor Valerie Plante urged people to check on vulnerable neighbors, including seniors.
"We see clearly that we're at the beginning of increases, which will continue to go up over the coming days", Drouin said.
For those in the hospital that have limited accessibility and extreme health issues, it's essentially impossible for them to leave their rooms in search of air conditioning.
In Toronto and Ottawa, temperatures have remained well above 30 C since Friday. Unless a family member decides to bring them a personal fan, they are left stuck in the same temperatures that could cause life-threatening situations. Heat warnings were also issued for much of Ontario, Nova Scotia and New Brunswick, according to Reuters. The advisory was expected to be in place until Thursday.
It's been said before and it'll be said again: this heat wave is never ending.
In Montreal, police and firefighters continued to go door to door in areas identified as having people considered at high risk: those with chronic illness or mental-health problems, those who live alone and people without air conditioning at home.
