Mr. Chair, may I respond to that question from a health point of view? It's somewhat different, but I hope this information is beneficial.
Part of being able to enforce is understanding if the actions we've taken have been effective. One of the things Canada struggles with, compared to other jurisdictions, is programs like biomonitoring, which tell how much of something is still in the blood. We take lead out of gas; we know how much is still in the environment, but we don't know how much is in people.
The act does call for the Minister of the Environment to maintain a national pollutant release inventory. It does not call for a similar requirement for the Minister of Health in terms of biomonitoring and understanding, so our ability to support enforcement is somewhat challenged by that lack of information. That doesn't mean we couldn't do it if we wanted to. There would be resource questions associated with that, obviously.
That is one area where there is a subtle difference that might help us in the information base we have.
