In terms of actual extra costs, I'm not in a place to estimate or judge. The energy data is widely available in Canada in a large number of places, but you have to be somewhat of an expert to find it easily. Companies will build that expertise and understand where to get the data they need, including from industry associations; provincial governments; certain other kinds of agencies, such as electricity system operators, which are non-governmental organizations; or one of the federal departments. They will build that capability, and it will add a bit of cost, but it's not that the data isn't available; sometimes it's not aggregated.
