it's not ridiculous since bonanno's are stronger than montreal mafia by far, no matter montreal is actually more violent that's only because the lack of anti-mafia laws in canada nothing more bonanno's in ny have 150 or more made members and they are full of zips they could easily send zips to montreal and kill whoever they want
Bonnanos are busy extorting hot-dog vendors and getting eastern-european prostitutes, not planning to take over the Montreal mob.
Sal was a zip and close to them and look where it got him.....dead. This is a Canadian thing.
