The autopsy on three charred bodies found near Barrie will take place early next week.
The autopsy was scheduled for today, but police said it was being delayed. No word on why.
Firefighters were called to Holick Road north of the 4th Line of Oro-Medonte Township, around 5:41 on Friday morning.
Once the flames were out, they found the bodies inside the vehicle.
Police aren't releasing the genders of the victims, only saying that they are waiting for the results of an autopsy.
The vehicle, with an Ontario plate, was burned beyond recognition.
