I think this is the top 3 in BC.

In Quebec for instance, Sicilians, Haitians and Lebanese seem to be much more influential in organized crime than Vietnamese or Punjabis are.
In Ontario on the other hand I hear more about Calabrian, Chinese, Jamaican, Somali and Tamil OC and gang activity - even though this Brampton, ON arrest seems to be a bit of an exception.
The prairie provinces have a higher rate of Native/First Nations OC.

Bikers of course are all over Canada and a major OC force in Quebec, BC and Ontario. Overall they're probably the most powerful OC group when you take Canada in general.

I find it a bit strange that Punjabis are so embroiled in OC activity in BC and Brampton. Over here in Europe, Punjabis are very peaceful and they just open up night shops lol
