The brief answer is yes, we have done some updated work, which I think we can share. The first analysis you were referring to, Mr. Barlow, was done, I think, prior to the backstop being designed, and was based, as you said, on $25 a tonne, a fairly high level. We've refined some of that work since then. I don't have it in front of me.
Maybe the only caveat, from a straight analytical point, is that it is partial, because we don't have the provincial.... The minister talked about the provinces and their designing of the tax or the price, but also what they do with the generated funds and how they reinvest them into their provincial economies.
