"The majority of people who have died in Montreal were part of those vulnerable during extreme heat conditions", said Kaiser.
And late Wednesday two more deaths blamed on the heat were recorded in a Montreal suburb, Radio Canada reported.
Environment Canada lifted heat warnings for the regions, including Quebec, for the next several days.
"What we know is, first they have heat stroke". Signs of heat illness could include cramps and rashes, and among the people with the highest risk of suffering are generally older adults, young children, the homeless and people with chronic illnesses.
None of the victims had air conditioning and many died inside of their homes, says Kaiser.
Prior to this, the only heat wave that Parent remembers being so memorable was a four to five day period in 2010.
