Ontario Provincial Police are investigating a fatal collision in Wellington County.
It happened Saturday evening around 8:30 p.m. on Wellington Rd. 44 just south of Wellington Rd. 7, outside of Rockwood. Police say it involved a sedan and a pickup truck.
One passenger, a 35-year-old Fergus man, was pronounced dead at the scene. A 17-year-old male passenger and the 45-year-old female driver, from the same vehicle, were rushed by ambulance to a local hospital with severe, life-threatening injuries and were later pronounced deceased.
The driver of the other vehicle, a 50-year-old man from Barrie, was not hurt.
The deceased have not been identified and police say they will not be until loved ones have been notified.
