No, all- powerful as the EPA can be, its jurisdiction does not cross international borders.
We are seeing a lot of motorcycle exhaust attention from LEO's here in the northeast US too. It is the result of so many bikes with open pipes and the fact that exhaust rules (both emissions and noise) have not really been enforced for quite a few years and the situation has gotten out of hand.
As someone already said, all exhausts used on motorcycles in the US have to be qualified by the fed. gov't. Further, the exhausts are qualified on a specific motorcycle. Factory mufflers carry a certification number while most aftermarket exhausts do not. So an aftermarket exhaust is technically illegal because it has not specifically been made legal (kind of backwards but this is how it works) What we are seeing here is that blanket law being applied to specific motorcycles; an LEO rarely bothers anyone unless the bike hurt his ears and shook the car windows in the first place. Upon inspection, it turns out to be an uncertified exhaust.
Several communities in this area are also using pretty large fines for bikes that are "too loud". The problem is trying to define an actual sound pressure measurement; it is difficult to get a valid measurement and even things like what kind of ground is under the vehicle makes large changes in the readings so it is easy to challenge any tickets in court. But just finding an aftermarket (and uncertified) exhaust on a motorcycle is a much easier way to ticket the rider without having to quantify or measure anything like the actual sound output.

Does the EPA have jurisdiction in Canada?
100dB is pretty loud... I don't think I'd want something that loud on my bike... except for the horn, of course.
The fact that his community has recently passed this means that they WILL be looking for it, at least for a while. I'm with Bosco... confirm that their criteria is 5000 RPM at 20", and try to run that test yourself... so you are informed if you ever get pulled over.
