Ian Douglas Dickson was a visitor from Scotland who disappeared in Toronto in the spring of 1991. The last confirmed sighting was the afternoon of May 12, when he was seen leaving a restaurant near Yonge Street and Eglinton Avenue. He was due to fly home on May 23 but never boarded the flight.

At the time he vanished he was described as slender to thin, fair complected, about 69 inches tall and 161 pounds, with wavy red hair and a scar on his left leg. He was wearing blue denim pants and brown leather dress shoes when last seen. Little else about his reasons for visiting Toronto or his activities there appears in publicly accessible records.

The trail went cold after May 12; there are no publicly detailed leads or confirmed movements after he left the restaurant. Did anyone in Toronto in May 1991 see Ian or recall him around Yonge and Eglinton?
