I don't know about the activity of Desjardin's group since he's been in prison, but at most "internal" could mean within the overall milieu and not just the Montreal Mob. When you consider that, and the fact that Desjardin's & his camp have no recent reported links with the Montreal underworld, I don't see it coming from him.
And part of the recent bust involving Leonardo Rizzuto, Stefano Sollecito & Gregory Woollery has Mom Boucher making an request for Desjardins life. Both of those men are on the inside, personally, if I were Desjardins, I'd have more important, immediate things to worry about. But you never know.
