We have such a law in Quebec now. As I mentioned as they were preparing the law, the problem was enforcement. These robots can come from anywhere in the world. We've seen them from eastern European countries. We've also seen them from within Montreal. If there's no ability to pursue them outside the province, they'll just move across the border and keep doing what they're doing.
Technology has a better chance of stopping it than the law, but of course, as Erin said, you have to have the law in place in the first place.
