The Cotroni crime family, originally Cotrone (Italian: [koˈtroːni]) is an organized crime family based in Montreal, Quebec, Canada. The FBI considered the family a branch of the Bonanno crime family. A Calabrian immigrant from Mammola, Vincenzo Cotroni established the organization in the 1940s. Their territory once covered most of southern Quebec and Ontario. An internal war broke out between the Calabrian and Sicilian factions of the family in the late 1970s, which resulted in the death of acting captain Paolo Violi and his brothers. This allowed the Sicilian Rizzuto crime family to overtake the Cotronis as the preeminent crime family in Montreal. Vincenzo died of cancer in 1984, followed by his brother Frank in 2004.
