Indeed, you can also see this with the top guys from the Gangster Disciples, Black Mafia, Black Guerilla Family, La Eme, Aryan Brotherhood, Netas, Trinitarios,...even the more organized Asian gangs. The guys at the top of these gangs don't really look like stereotypical gangbangers at all.
But still, gangs in Montreal are really one of a kind. If you take a look at the Hells Angels in Montreal ( and Quebec in general) you can see that they are a bit different from biker gangs you tend to see in Europe or Australia. In Montreal they look more like mobsters than stereotypical bikers.
