*Ambient temperatures from observations at Pierre Elliott Trudeau International Airport.
†n = 14 861 postal codes of residences.
‡Only one surface map was used for decedents and the surface temperature attributed to a postal code of place of death thus remains the same during control and hazard periods; n = 4790 postal codes at the places of death.
