 Cazzetta has often been described as controlling all of the organized crime in Montreal that was not controlled by the Mafia in the late 1980s-early 1990s.The Hells Angels had first entered Quebec in 1977, but the group was badly weakened by the Lennoxville massacre on 24 March 1985 when five members of the Angels' chapter in Laval were shot by their colleagues.Afterward, the vacuum was filled by a number of Montreal-based organized crime groups such as the Rock Machine, and it was not until the early 1990s that the Angels became a major force in Montreal organized crime again.
