We did two scenarios. One scenario has carbon pricing in Canada going up to $50 in 2022, similar to the pan-Canadian framework. The other one has it continuing to rise by $5 a year after that. In both of those cases, we actually increase our consumption of natural gas for power generation, because it has lower GHGs than other forms. Plus, it has other benefits. You can bring it on quickly, and it's relatively cheap. It's a good backup for renewable energy, and so on.
