There were probably multiple reasons, and I think that Electricity Canada has a pretty good brief on some of the headwinds facing them.
I think one is that, again, the cheapest hydroelectricity or the best hydroelectricity resources have been exhausted, so we aren't building as much hydroelectricity as we used to. There was quite a sharp decline in hydroelectricity. Nuclear also faced some headwinds, so there were not a lot of nuclear builds, but that's increasing. That is one bright spot, I would say, in Canada's electricity grid right now: the refurbishments in Ontario.
Also, there are permitting and transmission costs. All those kinds of things have provided headwinds. As well, there was probably more industrial demand in 2014. That was a period of relative economic boom in Canada. There was a significant heavy industry, with a lot of build-out, for example, in the oil sands, and that has decreased over the last 10 years.
It's some combination of all those factors.
