People in Ontario are feeling the worst of a heat wave on Tuesday as forecasters predict temperatures to reach the mid- to high 30s, and humidex readings near the mid-40s.
Much of northern Ontario is under heat warning, spanning areas from Kenora and Thunder Bay to Fort Hope and Timmins.
Environment Canada forecasters said those areas could see highs of 36 C, with the humidex making it feel as hot as 42 C, before letting up on Wednesday.
Other areas in southern Ontario, including Windsor, Toronto, North Bay and east to Ottawa and Cornwall, are also under heat warnings, with temperatures possibly reaching a maximum of 37 C and humidex reaching 45 C in some areas.
How to spot the warning signs of heat-related illness
Several municipalities, including Toronto and Hamilton, have opened cooling stations and pools for residents to keep out of the heat.
The City of Toronto said several outdoor pools will be open until just before midnight on Tuesday to help people cool down.
Officials in Vaughan, north of Toronto, also said they extended splash pad hours this week from 9 a.m. to 9 p.m.
Meanwhile, similar temperatures being felt in southern Manitoba are expected to even out, with daytime highs set to drop to the low-30s or high-20s for the rest of the week.
