One thing that you alluded to, something that really concerns me, is the issue of carbon leakage. We have increased carbon taxes and put in clean fuel standards, but as we know, most of the mining done by Canadian companies is being done abroad. When we're talking about the input costs increasing with carbon prices and without any sort of offsets that they can use, are we really just seeing mining being outsourced to other countries and Canada not producing our world-class environmental deposits here?
