In term of pure strength in Quebec, right now the mafia is too much divised. They need to make alliance with other groups to make war. Also, the mafia don’t have a good pool in the italian community to comite murders. While the haitians and the bikers can take a young guy in his 20s ro kill someone for not mich money.
The Hells Angels and Wolley’s organisation are probably the strongest factors in term of a war.
i think they use hired killers because they have money to pay them the mafia is by far richer than bikers and haitians it has politics links, involvement in constructions , waste etc. not in street stuff only in other words the most powerful
