Whether it's federally imposed and they pre-empt their provincial policies or there's bottom-up alignment.... We've done analysis in modelling going back to the national round table in 2008. We found that continued fragmentation increased the cost by about 25%. In the pan-Canadian framework milieu, looking at provincial policies, scaling them up and aligning them, the alignment of carbon pricing knocks about $50 off the carbon price. It's a fairly significant chunk, to the extent that you can basically grab low-cost reductions and various trade reductions within the federation and not strand low-cost opportunities somewhere else.
