Igor Tikhomirov was a man in his late twenties who was last seen on May 12, 1996, aboard an oil tanker on Lake Ontario. The tanker was traveling from Holland to Sarnia when Tikhomirov was observed going overboard.

His personal effects remained in his cabin — an older record states that all of his belongings were left behind and there is no indication he gathered possessions or prepared to leave the ship. Reports differ on whether he deliberately jumped or accidentally fell; that key circumstance remains unresolved. Searches did not recover a body, and drowning is described as the presumed outcome but without physical confirmation.

Descriptions circulated after his disappearance list him as slim-built, about 5 feet 10 inches and 154 pounds, with short brown hair that did not extend below his collar, and brown eyes; he was last seen wearing a light blue T-shirt, light brown casual pants and casual footwear. Tips are directed to Ontario Provincial Police missing-person investigators. Does anyone who worked on tankers on Lake Ontario in 1996 or who knew Igor have information that could help clarify what happened?
