I agree with Cun trera , Scoppa or Cotroni but not so sure about Sollecito or Arcadi they seem to lack respect from the ranks.
Desjardins himself admitted that he can never be boss because he wasn't Italian. This was caught in surveillance tapes. The rising star Mirarchi is a possibility, he seems to have ties to the Ndrangheta in Ontario.
Not as a boss of the Italians, but Raynald is a leader in his own right.
