TORONTO — 1919 · Missing Person

The Disappearance of Ambrose Small

UnsolvedSources: ALast updated: 14 October 2026

In late November 1919, Toronto theatre magnate Ambrose Small and his wife sold their chain of theatres for about 1.7 million dollars, receiving a one-million-dollar payment on account on 1 December. The next day, 2 December 1919, after meeting his lawyer at the Grand Opera House in the afternoon, Small disappeared without a trace. In January 1920 rewards were posted and an international search began. A former employee was convicted of stealing bonds from Small's bank box, but no one was ever charged with kidnapping or murder, and no body was found. Small was declared dead for probate purposes in 1923. The disappearance is remembered as Toronto's most famous unsolved mystery.
