If you compare the Montreal Mafia as a whole with the Bonannos then Montreal will be on par with that family if you include all associates. The Rizzutos had a supervisory role in Montreal, but they did not control everybody as is the case in a streamlined organization like a New York family. And within the traditional hierarchy they were subservient to the Bonannos. If you look at power you have to look at longevity as well. The Bonanno organization has been in existance long before the Rizzutos formed their own and despite many setbacks are still a viable organization while the Rizzutos are now dispersed and weakened. History has shown the families in New York are much more solid than whatever is in Canada, which also happens to be the reason why Canada is far more intriguing for me. New York is really boring nowadays compared to what is happening north of the border.
