I firmly believe that the Calabrian/Ndrangheta are responsible for the Rizzuto Family murders. The 7 clans from Toronto have taken over the drug trade in Canada and Montreal was their main goal to tighten their control of the market. Not to mention The Rizzutos were responsible for whacking out The Calabrians to take control of Montreal. It's 1 part drug trade takeover and 1 part revenge.
There's been speculation that there was tacit support from the 'Ndrangheta but the killings were obviously the work of a breakaway group from the Rizzutos. And I don't think we've seen any signs of the 'Ndrangheta taking control of the drug trade in Montreal.
