Police say the charred remains found in a burned-out car north of Toronto last week belong to a previously missing Mississauga man and two boys, aged 10 and 4.
Samuel Masih, 36, and his sons were reported missing early last Friday by the children's mother after they failed to return from a movie.
Hours later, police were called to a car fire in Oro-Medonte Township, near Barrie, Ont., and discovered that the vehicle contained the remains of three people.
Ontario Provincial Police say postmortem exams conducted on Tuesday confirmed the identities of the bodies, but investigators say they are not releasing the names of the children.
The case remains under investigation and police say they are not releasing how the three died.
The OPP is asking anyone who saw any unusual activity in the area of Holick Road on July 3 or 4, 2014, to contact investigators.
