Three-year-old boy unharmed after being left in cold car for 40 minutes York Region police are investigating after a toddler was reportedly left unattended inside a parked car during frigid temperatures. The three-year old child was apparently left in a car in a Markham, Ont., parking lot Tuesday for about 40 minutes. Police say the boy was found asleep in the vehicle at around 7 p.m. when it was about minus-14 and did not respond when officers tried to wake him by tapping on a window. But the toddler was dressed for the weather and was unharmed. The boy's 39-year-old father is under investigation.
