Thank you for that, because I think people were concerned with the exposure we did have, notwithstanding that our banks were more highly capitalized and had stronger requirements. Nonetheless, it turns out that a number of our banks were investing in sub-prime mortgages. According to the document we were just given, we're talking about up to 5% of mortgages in Canada. That is a very low number, but I think it was a surprise to many that we were involved in that fiasco.
You mentioned that we should be focused and strategic, and Canadians probably want to see that as well. You mentioned the borders. I noted that the former foreign affairs minister, David Emerson, has been out talking recently. His thesis is that the thickening of the borders has really created problems, and he's talking about an approach that is different from what we have had in the past in this country, a kind of customs union.
Based on your research, is there any consensus about where Canadians would like us to be more engaged with the Americans when it comes to manufacturing and markets? You mentioned food safety as regulatory, but I'm talking in terms of working sectorally in our economies.
