Allan Malcolm Mackenzie, a 52-year-old Toronto truck driver, disappeared after a delivery to the Ministry of Natural Resources in Chapleau, Ontario. On November 5, 1987, he completed the drop-off and was believed to be returning to Toronto in his distinctive red and green tractor-trailer, but he never arrived and was reported overdue.

His truck and trailer were later found parked and abandoned about 48 kilometers north of Sultan, Ontario, an odd, remote bush location off the expected route. Police searched the vehicle and surrounding area but found no sign of Mackenzie. He was described as 5 feet 11 inches, about 159 pounds, with short wavy brown hair, brown eyes and cross tattoos on both forearms; he was last seen wearing a blue polyester shirt, blue polyester pants and black leather army boots.

The Superior East detachment of the Ontario Provincial Police handled the investigation, which has not produced an explanation for his disappearance. Does anyone have information about Allan’s movements that day or recall seeing his truck in northern Ontario around November 5, 1987?
