Some parts of southern Ontario are under a Heat Warning today.
Environment Canada says the heat and humidity are expected to continue, possibly through to the middle of this week.
It says we should expect daytime highs near 30 to 32 degrees Celsius, with humidex values making it feel between 37 to 40.
With nighttime temperatures near 20-21 degrees, there will be little relief from the heat overnight either.
Watch for the effects of heat illness: swelling, rash, cramps, fainting, heat exhaustion, heat stroke and the worsening of some health conditions.
Also, PLEASE never leave people or pets inside a parked vehicle.

The Simcoe Muskoka District Health Unit says when temperatures are high, overexertion will increase the risk of heat exhaustion, dehydration, or heat stroke.
During the heat, you should be taking care to avoid overheating.
· Be sure to drink plenty of fluids (non-caffeinated). Don’t wait until you feel thirsty – that’s a signthat your body is already becoming dehydrated.
· Stay cool indoors.
· If you must be outside, stay in the shade and make sure you wear and reapply sunscreen, a broad-brimmed hat, sunglasses and lightweight, light-colored, loose-fitting clothing.
· Electric fans provide comfort by increasing evaporation, however when conditions are extreme, fans will not prevent heat-related illness.
· Keep physical activity to a minimum.
· Draw blinds or curtains to prevent radiant heat from entering homes.
Infants and young children, the frail elderly and people with chronic lung conditions or taking certain prescription drugs are more vulnerable to harm from overheating. Check in on these people to make surethey’re staying safe.
