These are thresholds that were established based on current science, presumably on the impact of these emissions on human health. This tax, presumably, would be layered upon the existing carbon taxes that are already in place across the country, or implied carbon taxes when you look at jurisdictions like Ontario and Quebec. So we have the carbon taxes in place, or carbon pricing, then we have pollution taxes layered on top of that. In some cases the same companies that are already paying the carbon tax are paying also a pollution tax. You can see the escalating burden that we're now imposing on companies across the country. I'm just concerned about the balance, with the environment and the economy going hand in hand, what impact it does to shift that balance.
