I would say that Detroit is definitely alive and well. I believe that their influence quite possibly extends into Ontario. Remember that the Rizzuto Family does not wield power there. Ontario is the home base of the Calabrians. Perhaps they are aligned. Furthermore, I would not be surprised if Tocco and the Syndicate have some sort of working relationship.

I may be fooling myself, but I stil believe that the Partnership is unlike any other family in the US in the means by which they conduct themselves. They are almost completely insulated.

At a minimum, nobody can write them off as NOT being viable. Whether they are powerful . . . nobody really knows.
