My bad, I misread the initial article on Scarcella and put him as boss of Commissio.

Yes, after Volpe was found murdered (Scarcella was the last person seen with him), it's alleged Scarcella took over all of Volpe's interests in Toronto. Raffele Delle Donne fingers Scarcella as a boss in Toronto. The Fifth Estate had an episode on Delle Donne flipping after the botched assassination attempt on Mike Modica. The Canadians were called in to do it from the Gambinos.
