People are also being told to check on loved ones or those who are vulnerable such as the elderly or those with illnesses.

As is the case during a heat wave, pets and children should never be left alone in a vehicle under the hot sun.

On Tuesday, York Regional Police had to smash a window of a parked vehicle in Markham after witnesses noticed an infant alone inside for at least 15 minutes.

The baby was taken out safely and did not suffer any injuries, but the parents were charged under the Child and Family Services Act for leaving the child unattended.
