I was saying that it's a diverse group of countries and that in most of these countries we are already quite active. I tried in my opening remarks to give you a sense of that.
It's hard to pin down a country. Certainly the NAFTA countries remain very important markets for us. After Europe, the U.S. remains for us overall the second-largest market, and it is the largest market for aviation for us. In Mexico, we see a lot of prospects for rail projects and for more aircraft. As for the other TPP countries, we're very present in Australia, and there are a lot of rail projects coming up, as well as aerospace opportunities. It's really across the board.
It's hard to really pin down just a couple of countries as presenting more opportunities than others. I think it's the whole region, really, but there are also very important economies that are currently not part of the TPP. To the extent that the TPP can serve as a template for trans-Pacific trade and that more countries can join, I think this is very much welcome. However, it should not prevent Canada, I think, from pursuing other trade agreements in the region, including with China and with India, because these are big pieces as well.
