I would just add a couple of points to that.
The standards example, where there is a clear federal role, is a good one because of the economies of scale of being able to do the thinking and because there is federal jurisdiction going to anything that transfers across borders, whether international or provincial. But with the provinces, they have direct jurisdiction to regulate things within the province. You need both of them; you can't actually pull this off in Canada without having both levels of government doing it.
One important part of this puzzle that we haven't talked about—and it's primarily provincial—is the regulators. Mr. Konow and I work very closely with the regulators in the provinces. They have a hugely important role in creating the right regulatory framework, through which demand-side management and energy efficiency programs will play. They need to work with their respective provincial governments and with the federal government to be able to do that.
