Sonny I agree that the drug traffic prob never stopped but I don't think any New York family has any say on anything that happens in Montreal or anywhere else in Canada. And traditionally the drug trafficking has been Montreal guys wholesaling to New York guys who distribute the drugs. More specifically it has been Sicilians in Montreal selling to Sicilians in New York who then distribute to others in the Five families. I don't think the Five families garner much respect from any mafia groups outside of the USA they have too many people turning to the government. The Genovese and the Gambinos maybe an exception to this rule.

Tommy Gambino I don't think the Rizzuto's were ever as decimated as they were portrayed. They have either taken Montreal back with little to no push back or they never lost power. Reports lately have the Rizzuto's working with the Hells Angels to once again fix drug prices.

Montagna was involved with a group of people who tried to take over the Rizzuto's most of this group was Montreal or Canadian based. I think the bigger power players in this group were montreal guys with close ties to Ndrangheta groups in Ontario. Montagna may have had influence in the murders of Paulo Renda, Nick Sr and prob Cu ntrera but how much say he had with the group of conspirators is highly debatable. Police have stated that Nick Rizzuto Jr and Nick Sr's murders were not related. Nick Jr was allegedly killed over a land dispute with a local mafia connected figure Tony Magi.

In the end Montagna was killed on orders a french canadian and with zero retaliation from Bonnano family. Giuseppe Renda another American Bonnano member who was closely aligned with Montagna disappeared in Montreal and is assumed dead. He was last seen with a member of the [BadWord] family once again no retaliation from Bonnano's. The body count on the side of those that opposed the Rizzuto's would now seem to be much higher than those who tried to over take them. The RIzzuto side would seem to have not taken any hits in almost 3 years now.

The five families don't need to be decimated by a takeover they are instead decimated by guys ratting one another out. Due to more stringent laws in the USA I don't think anybody could get away with waging a war like has happened in Montreal.
