Mr. Langan, I know that you're sort of a public advocate for this, but you talked early on about the excitement associated with the innovative technologies for Canada, but not necessarily for the rest of the world, that would flow into our economy as a result of embarking on a project like this, high speed, not higher speed. I gather you've done some studies as well on the number of jobs that would be created during the construction phase.
I think, Mr. Mackay, you were a part of those kinds of studies as well.
Have you got a sense of what some of those technologies might be? You haven't shared them with this committee and you've left us to imagine what they might be and to fill in the blanks.
