The difference is in the players,in the USA the mob isnt italian anymore when in Canada the ndrangheta and the Rizzuto still have strong relations with the mothrland and before the Rizzuto deportation the canadian mob was invisible and for the LE the big problem was the biker feud between the Hell Angels and the Rock Machine.
Plus more italians emigratrd to Canada intil the 1970s.
Conclusion the Canada is like the USA before Apalachin and Valachi flipping.
