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.
