NY lost the canadian branch when massino et al. had gerlando sciascia murdered in 1999. any tribute/tax or payments from MTL to the bonannos stopped after the murder if not before.
there was a period of a few yrs after the murder where the bonannos sent reps to MTL to appoint a new capo of MTL but these were all rebuffed by the rizzuto's.
the problem for the bonannos was the thinking that they still held any kind of power over the mafia in montreal. gerlando sciascia has often been mislabeled as the bonannos capo of montreal which is wrong. sciascia was the rizzutos rep in NY. sciascia reported directly to the rizzuto administration in montreal and hails from the same part of sicily as the rizzutos, cattolica eraclea.
the reason why nothing has been reported about the bonannos up in canada/montreal is that there is none. aside from salvatore montagna's failed attempt to takeover the city (2009-2011) in just the last 10 yrs there has been no credible info about the bonannos still having an active crew of soldiers in MTL that have allegiance only to the bonannos.
i would be curious and it has been mentioned on other threads about whom damiano zummo is acting capo for and how he had enough clout to lead an induction ceremony in canada in 2015. this ceremony inducted an informant which lead to the eventual arrest of zummo as well as the Violi bros. in 2017.
that would put any power of the bonannos in the southern part of ontario not MTL and allies of 'ndrangheta/buffalo crime family.
