After Sciascia was killed, the ties between the Bonanno family and the Montreal faction were severed more or less. The Rizzutos had been running things mostly independently for some time anyway. What was interesting however, is that it later came out that Vito Rizzuto said he wasn't going to answer to Montagna in New York. That he would need to make that clear shows there continued to be some kind of connection between them. But who knows how things will end up in Montreal once the smoke clears. It is more a case of two separate entities now, not one "answering" to the other. Certainly not New York answering to Montreal. The Rizzutos were a faction of the Bonanno family, not the other way around, despite what many "Sixth Family" theories proclaimed.
