One of the best things that we can provide you with, Mr. Bonin, is the decision document. Under the Governor in Council decision, there was an explanatory note. It's 38 pages. It lays out all the considerations that we at the Major Projects Office made and advised on, which the GIC then considered in the decision.
In that decision, you'll see that we not only did work but also had third party work, in which we assessed, first of all, the viability of the pipeline as a project of national interest, whether it would be economical.
We assessed the demand and supply for Canadian heavy crude oil from the Asian market. We assessed the differentials that would occur to all Canadians from the revenues that we would receive, because, as you know, when we sell our oil to the United States, we sell it at a deep discount. I think today that is $28. When we sell it to Asia, we sell it at a premium, which today would be $14. There's about a $50 price differential there that we, as a country, lose when we sell our oil to the U.S.
Of course, as you know, the oil sands companies have to provide the oil into the pipeline, and they have to pay the toll, so we assess the economics of the toll and the ability to return the money back to the governments of Alberta and Canada through the investment in the pipeline.
All of that is laid out in our decision document.
