Its crazy how things changed. In the 90s and 00s, montreal was crazy (by canadian standards). But at those times, must gangs leaders we’re in the mid-20s, and not many in their 30s.
But now, many of those gang leaders are in their 40s and 50s, you also have but a few in their mid-50s almost 60.
So age does have a big importance in organized crime. Because a teen or young adult in his 20 or 30 is more impulsive. But if you have older heads leading the way, its always better.

Also, the street gangs of montreal learned alot from the mafia and the bikers, who were older than them and had more contacts.
We could say, their is an black organized crime in Montreal, that is above the normal street gangs.
