Gary Douglas Millerson, also known by the alias Gary Brian Melunchuk, was last seen at his Port McNicoll, Ontario residence on April 19, 1991. He was 29 at the time and born December 29, 1961. Described as a Caucasian male about 6 feet tall and 209 pounds, he had black hair, brown eyes, a moustache, a scar on his left cheek, heavily tattooed arms and a healed broken femur from youth. He was reportedly wearing grey cotton pants and a grey and black cotton sweater when he vanished.

The Southern Georgian Bay OPP maintains the case. Circumstances of his disappearance are sparse: he was last seen at home and there is no clear indication of his intentions or destination. The investigation remains open and the family has continued to seek information. If anyone knew Gary, saw him in Port McNicoll around April 19, 1991, or has information that could help, please come forward.
