the rizzuto/sollecito faction of the montreal mafia is its own family.
the rizzuto crime family that was lead by nick sr. and vito (from 1993-2013) roughly had by the time of sciascias murder eclipsed not just the bonannos in power and influence but the colombos,lucchese and decavalcante in ny/nj area and most other mafia crime families in the u.s. in the same period.
i know for mafia authors and some online like jerry capeci this idea is laughable but the rizzutos were running for that 20 yr period a sophisticated,ruthless,cunning and powerful mafia family. they had setup in canada alliances w/ HA,street gangs asian syndicates and transnational drug cartels to put a lock on the city of mtl,the province of quebec as a whole with influence extending into ontario. the rizzuto crime family also had extensive connections back to sicily.
and the bonannos were never in any position to do anything. what would the bonannos have done sent a hit team up to mtl and take them all out.
tha bonannos were so rife w/ turncoats and rats noone in that family at the time could be trusted to properly do anything.
the proof of this is that even after the one time acting boss montagna was murdered and whether he was well liked or not the bonannos did nothing.
montagna was murdered by a frenchman (raynald desjardins and others) not the rizzuto's. so the bonannos after a made member was murdered by a non italian did fat squat to avenge the murder. there was no one even in mtl who did anything.
