It would be very helpful, and not only the heavier enforcement measures but some of the lighter ones that have been implemented.
Perhaps I could ask another question as well. You mentioned the six greenhouse gases that are regulated, but there's a whole host of non-greenhouse gas emissions that are also regulated by you that are created by the burning of fossil fuels. To what degree has progress been made in regulating those and decreasing the presence of those within our airsheds across Canada, say, over the last 10 years?
