no idea if this cell is calabrian or not nor should that matter.
i am in no way trying to start anything unlike whatever has been transpiring on this site today but the sicilian v. calabrian thing is overblown.
there are some calabrians in MTL there r some sicilians both operating all over the place with a variety of criminal partners.
as most media has reported there appeared to be a "truce" between warring factions.

with that being said 2 groups in the R.D.P/mtl north area are fighting over territory.
the barberio-pizzi cell being one.
the new intell which is always good is that the oliviero-lopez cell leader is serafino oliviero.
his 3 nephews franco,giuseppe and pasquale operate under him as wholesale cocaine distributors in the mtl north area.
all 4 of these men are currently out on the street.

how any of this connects to the murder of piero arena i am still not sure.
in both areas there has also been ongoing feuds with the local street gangs some of which are allied with the blues some with reds some with the mafia and some with the HA.
all around making for a confusing situation.

again i don't mean to toss aside your question.
