Keep in mind Montreal isn't America..And the Rizzutos were always more comparable and associated more with Sicilian Mafia Families than US La Cosa Nostra families. Theres no disputing Leonardo Rizzuto is one of the bosses of the Montreal Mafia. And you've never heard of a son taking over the fathers role of boss in an American Family? You've never heard of John And Junior Gotti then? Or Joe and Bill Bonanno? Or the Toccos and Zerillis of Detroit?
