We didn't specifically look at the economic benefits of this expansion, but in previous reports we looked at what it would mean to have the Canadian oil. We looked at Western Canada Select and getting a better price for that commodity. We didn't look at expanding production or anything like that, but what it could do to the price that producers can get if more markets were available for WCS, as we call it.
We estimated, I think in 2018, that a $5 increase in the price of Canadian oil—so the discount being smaller—would lead to $6 billion of additional benefits for the Canadian economy. That was in 2018, so one can assume that it's increased since then, and we have not updated that number. Assuming that it's still the same number and the government is taking about 15% as usual, the federal government benefits to the tune of about 15% on economic activity, generally speaking, so at $6 billion, right there, if you do simple math, it's about a billion dollars more in federal tax revenues if that was the reduction in the discount at which Canadian oil sells.
Just from the federal government's perspective, there are significant amounts of money in additional tax revenue each and every year that the pipeline is in operation.
