If im not mistaken, the Cotronis have always been extremely close to the french-canadian community and by extension the bikers.
Most likely, the criminal map is being re-drawn within the city.
They said the Cotroni group was finished after the death of Frank in 2004, but it seems like they are still doing their own thing, they are deeply rooted in Quebec culture. I wouldn't besuprised if there is still a structure in place.
