These devices are extremely difficult to pinpoint. OEMs have their own challenges with identifying them. That is why we believe the best solution is a duplication of the Clean Air Act in Canada under CEPA, which would allow Environment Canada the enforcement powers to go after the manufacturers, distributors, resellers, and installers.
These people are brazen. They take out full-page ads now. It is easy to find them, much easier than to identify in a truck what's going on. As I said, it's not that we are against that idea. It was part of our recommendations to be part of PMVI, but it is extremely difficult. It's far more effective to go the other route.
