i try to relate it by country and even in the case of canada by province.
in the whole of canada there is no OC group bigger or more influential than the hells angels.
HA spans the country and if u aren't a HA chances r the drugs u sell came from them through the ports or from border crossings.
BUT...not all HA chapters have the same amount of influence and some don't appear to be involved in crime at all.
in quebec resides the 3 most influential chapters in canada in MTL,South and Trois Rivieres.these chapters have alliance with the mafia,independent importers of narcotics at all the major ports and control there own on street distribution through own members or alliance with street gangs.
so as an example the trois rivieres chapter could be the #1 crime group in all of canada even eclipsing mafia groups like the rizzutos and commissos in toronto just by strength in numbers,top to bottom ctrl of narcotics and total profits.in that same thought it could be one of the most influential chapters in the world(remember just an example).
another example in canada would be a HA chapter on the west coast in BC/vancouver as it may have alliance with a mexican cartel for drug import,money laundering through triads/chinese criminals and the same type of top to bottom ctrl of drugs.
