I'll be quick, because the list is potentially very long. In addition to the comments that we have been making about infrastructure that supports external trade, I will emphasize that there is a lot of opportunity for us to support ourselves in Canada by liberalizing internal trade.
It's a tough file, because many of the things that need doing are small-looking regulatory differences. It's not very exciting to address them. In fact, it can be very tedious to address them, and every barrier has its own justifications and vested interests. Some of the estimates of how big a boost to GDP we can get by knocking down internal trade barriers are probably a little ambitious, but there's a lot to be done there. Of course, we're not dependent on anyone other than ourselves to reap some of those benefits, so that's a good investment.
