That's a great question. You are asking thoughtful, perceptive questions of us.
Let's imagine we were to set solid, evidence-based air quality objectives for Canada, and maybe even they're enforceable. We do a great job of controlling point sources, cleaner vehicles, but we import a lot of pollution from other countries. I don't know that CEPA can be enforceable in that area. It's not just from our neighbours south of the border, but from other countries; dust from the Sahara can migrate all the way to Canada. There may be a way to build on CEPA and have some international agreements within the Great Lakes basin or the Lower Mainland of B.C. so that we could try to work in a co-operative manner with the international community.
