Yes, but what do you mean by "involved?" Were/are some guys in the Rizzuto organization at least nominally Bonanno members? Yes. Do some NY guys and Canadian guys know each other? Yes. Was Rizzuto apparently in contact with people in New York when he said he didn't recognize Montagna as his boss? Yes. But Montagna getting involved in things up there probably had as much to do with the fact that he was deported there (since he was from there) as anything. Not necessarily the Bonannos becoming "involved."

Involved, to me, means being involved in the politics and/or rackets of the Rizzutos. The politics? That jury is still out on that to some degree. But the rackets? I can't really think of anything. The mob's scope, including the Bonanno family, has become smaller. The hub of the "Bonanno universe" is Brooklyn, Queens, Staten Island, etc. Heck, they have more "involvement" in Florida than they do in Montreal.
