After firefighters put out the blaze, they found the man’s body in the back seat of the blue four-door 2006 Hyundai Elantra.
Police say a forensics pathologist determined that there was no evidence of foul play and that the death was accidental.
As the death has been determined to be non-criminal, the name of the man who died is not being released.
Police said that five other people had been inside the vehicle before the fire. The passengers were interviewed by police, and told officers they left the car. The passengers said two Good Samaritans gave them a ride to the nearby Mosquito First Nation.
Anyone who may have had contact with the people in the car or the Good Samaritans is asked to call RCMP or Crime Stoppers at 1-800-222-8477.
