Thank you, Mr. Chair.
Thank you, everyone, for being here today, and thanks for that presentation. It was very informative and I think it reflects some of the conclusions or some of the information that we're hearing, too, when the committee does its work. It's nice to see it all in one document. I think that's going to prove very helpful as we go along in this process.
I have a question for you, Mr. Downs. I'll start with you just briefly with regard to the economic assessment, maybe in comparison to the other economic assessments, or so-called economic assessments, that are out there. When I was studying economics at Rotman, Doug Hyatt was my economics professor, and he always said that the outcome is often based on the assumptions.
When you compare these economic assessments—I presume they're peer-reviewed to begin with—are people using different assumptions that will lead to different outcomes and different conclusions?
