Those two are the one's I had in mind. The book Business or Blood on page 184 mentions that the Coluccio's were central to the Ndrangheta push into Montreal. Bruzzese(Coluccio's father-in-law) at one point had good relations with Rizzuto but I guess they decided to take advantage when he was jailed. The book also confirms that the Commisso/Rizzuto relations were not good. The Commisso's are related by marriage to the Luppino's which puts the Violi's in good standing.
