That's a very good question.
I think it's good that there is the C.D. Howe estimate so that we can compare that with the government estimate and show what the different assumptions were. Often, whenever you're doing economic analysis, it really depends what your assumptions were. You're going to get very different answers. Just having one headline is often not useful to having an honest understanding of what the impact of the deal would be. Making the data available and transparent as to how they arrived at their decision—making the model they used publicly available and allowing others to run the model—might be something to do.
I think moving it to the parliamentary budget office or something like that would also be helpful in improving that transparency. I don't think we want to rely on the C.D. Howe Institute or other groups to have to do that every time. I do think it's useful that they did. I'm glad they did, because it highlights that the choices you make in your modelling really matter.
