It has been a combination of things.
First of all, I think our country's decision to wean ourselves off coal is a significant variable in that. As you know, we're looking at stopping coal by 2030. I think, in some provinces, it will probably be 2040, with respect to some flexibility in those economic regions. I think getting off coal is important.
Second, simply, is innovation. We have a huge investment bill to renew our infrastructure. The Conference Board of Canada estimated some years ago that we have to spend in the order of $350 billion by 2030, but that's not just about replacing old with old. It's about replacing old with new and innovative. I think innovation has a lot to do with that. Our firms are investing roughly $20 billion annually on this innovation and infrastructure, and the outcomes are telling.
