Hot and humid air can deteriorate air quality and the agency encourages people to watch for the effects of heat illness, including swelling, rash, cramps, fainting, heat exhaustion, heatstroke, and the worsening of some health conditions.

Heat warnings are issued by Environment Canada when temperatures reach high enough to cause an elevated risk of heat illnesses.

The start of the workweek, however, is shaping up to be a little cooler than the last one.

Monday will be a mix of sun and clouds, though still hot with a high of 28ºC and a humidex reaching 35ºC during the day and a low 17ºC at night.

While Tuesday is predicted to see clouds with high 24ºC during the day, and lows of 18ºC with chances of showers at night.
