Bikers always had italians in their ranks. Well in Quebec.
Cazzetta and his brother were always bikers. Since the 80s, maybe even before.
The Quebec biker scene is more diverse than the one in the US. Hells Angels in Quebec also have natives in their ranks. Puppets clubs even have many black members.
Supposely Casper Ouinet even talk about the fact that the Syndicates wanted to be official Hells Angels, but it was denied because of Hells politics.

I think, it was because of the prison politic in the US.
