From the Mope&Wail’s business pages, discussing the closure of Goodman and Carr LLP:

Previously, the biggest law firm to shut down was Toronto-based Holden Day Wilson LLP in 1996. Holden Day at its peak had 90 lawyers after a merger in 1990, but the firm was devastated in 1993 by a fatal accident involving popular partner, Garry Hoy, who playfully took a run at a window during a reception at the Toronto-Dominion Centre.

In front of dozens of lawyers, the window gave way and Mr. Hoy fell to his death 24 floors below.
