In this context, it’s irrelevant whether a Canadian ‘ndrina answers to Italy or not.
Being Calabrian doesn’t automatically make them against the Rizzuto/Sicilians.
Why do you even have idea it would make them against Sicilians ? 'Ndrangheta and Sicilian mafia are working together,very closely back in Italy. Sicily being biggest producer of weed in Europe , supply them with weed in return of cocaine. Then u have members who are both members of Sicilian mafia & 'Ndrangehta.
