The organized crime groups are undoubtedly international. They don't recognize borders at all. Other than the physicality of having to cross a border at some point, when it comes to the online sites and whatnot that are doing this illegally, borders are not an issue. They will fill any gap. If there is more business to be had in Canada because of an unregulated system, then they will fill that gap. They will provide the service.
I think 15 U.S. states so far, and more to come, have regulated with similar legislation. They're going to look for the weak spots. If the weak spot is Canada and there's more money to be made here, they'll operate here.
