Garry Hoy (January 1, 1955 – July 9, 1993) was a lawyer for the law firm of Holden Day Wilson in Toronto who became notorious for the circumstances of his death.
In an attempt to prove to a group of prospective articling students that the glass windows of the Toronto-Dominion Centre were unbreakable, Hoy threw himself at a glass wall on the 24th floor.
The glass did not break, but the window frame gave way and he fell to his death.
