I'll start my answer to the question with respect to the costs of that particular chapter of the Agreement on Internal Trade with a general comment that it's a question often asked.
I'll say two things. First, we did a study several years ago at the Canadian Chamber that tried to come up with a bit of a global impact in terms of what the barriers to internal trade and the movement of goods and people and services in the country were costing the economy at the time. So we have some old data on that.
I think it's fair to say--and my colleague Mr. McKinstry just recently appeared before the Senate banking committee on this issue--that I don't think we have anything specific today.
Rob, maybe you can add to the answer I've just provided.
