We haven't done that specific calculation. We have had a look at the Turning the Corner plan; we at least tried to get an estimate of what the cost exposure would be, so to speak, of the obligations this would have imposed on us. And even at much lower carbon prices than $200, it was into the tens of millions of dollars. I think what's important to understand is, first, that's bottom-line cost; that just flows right through to the bottom line. But, second, looking to the future, it changes the investment dynamic.
So the trade impacts are important and would be real, but we also have to have—and this is the longer-term concern—an investment environment in Canada that will continue to attract investment, because there are options.
