Sweltering heat is moving into Northwestern Ontario.
Areas west of Lake Superior will experience temperatures into the 30's today and Saturday.
Make sure to drink plenty of water and stay in a cool place. Check on older family, friends, and neighbors, and never leave people or pets inside a parked vehicle.
Cooler air is expected to arrive on Sunday.
It's not only heat but also smoke from nearby forest fires.
Smoke plumes from a forest fire east of Pikangikum have resulted in deteriorated air quality in the area.
