I worked for Transport Canada in the past, and they have very strict rules. It's hard to change any of them. It would be a major overhaul and a major introspection for them to look at the European standards, compare them with our own, and then decide to accept what the Europeans are doing. If they have a new standard coming up in two years, they're going to accept that voluntarily without having anything to say about it. In Canada, the safety standards are based on the American standards, although they differ a little with daytime running lights, labels, and stuff.
