That's not 100% true with canada;
I mean, it's true there's no specific single act that targets what RICO covers but rather a network of different criminal legislation that cumulatively add up to have the same effect.
You can see Canada's effective use of these laws in prosecuting Winnipeg's Hell's Angels chapter in the late 90's/early 00's.
And does anyone actually take TheArm seriously? I mean, for all his talk of how pathetic "internet tough guys" are, he sure does act like one. Whenever I see a post from him I just roll my eyes and scroll right past it. Engaging him is just asking to get into a lose-lose situation with a troll.
