Mr. Holland, let's not get into a discussion. We're trying to move on here and make some progress.
This is just a gentle reminder, as we've all been reminded at every meeting, that we are trying to stay focused on Bill C-30, and today's topic is air pollution. There inevitably will be some wandering. There always is, and that's fine. But let's try to remember that today's topic is primarily air pollution and stick to that.
Let's not waste any more time on that.
Mr. Drouin, from the Montreal Public Health Authority, you have ten minutes, please.
