Italians in Canada are mostly 2nd and 3rd generation so their links to the continent tend to be much stronger. People in Montreal and Toronto still speak their local dialects, origins do matter in mafia circles although it's more diversified in North America vs Italy
Canadian authors have rarely grasped the concept of cultural origins within mafia circles and have made multiple mistake in the last few years with respect to who comes from where.
Mobsters like Di Maulo or Mucci became criminals here and we're not initiated into any organization back home mainly because mafia tradition is mostly found in Calabria Sicily and Naples.
The so called Calabrians in Montreal are merely a loose federation or criminals with different ethnic roots much like the Rizzutos had various people from different parts of Italy
The more insular Toronto ndrangheta is composed mainly of Calabrians but even then, associates can be from others parts
