Environment Canada says the hot and humid conditions may last as long as next week.
Parry Sound and Muskoka are under a heat warning as we could see temperatures rise close to 40 degrees with the humidex. Meteorologist Peter Kimbell says these conditions are here to stay for potentially the next week.
Environment Canada is reminding everyone to commonly visit neighbours, friends and older family members, especially those who are chronically ill, to make sure that they are cool and hydrated.
