The word from provincial police right now: don't leave pets or children in hot vehicles.
Norfolk County OPP responded to concerned calls about a driver leaving their dog inside the car when running into a store.
Ed Sanchuk of the OPP says, vehicles left in the sun can reach extremely high temperatures.
"On a day when temperatures are 26 degrees celsius, the temperature inside a vehicle parked in the shade can reach up to 32 degrees celsius. And if you leave your motor vehicle in the sun, the temperature can reach a staggering 71 degrees celsius - and this is extremely hot."
Sanchuk is asking motorists to leave their pets at home during this hot weather if you're planning on making stops along the way.
He is urging the public to leave their pets in a comfortable spot - at home.
Sanchuk adds, we should not be leaving our pets in any unattended vehicles in the summer or winter months.
