First of all, we rely for statistics on Statistics Canada, which provides us quarterly reports. We also subscribe to services and research provided by the Conference Board of Canada. They don't distinguish between trips and individuals. The vast majority of trips continue to be trips to the United States. There is some indication that day trips to the United States have diminished somewhat as a result of the recent economic situation and of the imposition of the WHTI. But grosso modo, probably—I mentioned in my speech that there are 1.5 million travellers to popular destinations in the Caribbean—there are seven million or eight million who travel abroad every year.
We can't track, for example, dual nationalities: people who leave Canada and enter another country on their other passport, if they go back to their birth home. What we see is a changing profile in travel. For young people a generation ago, it was back-packing around Europe; now it's going to work for Habitat for Humanity in Guatemala, or it's doing all kinds of eco-tourism, and we have medical tourism and a huge growth in the cruise industry. So it's not just the numbers; it's also the profile of the services we have to be ready to provide.
I'll leave you with one last example. In the U.K., medical tourism, and this is in some cases for relatively minor surgeries, reached a volume of about 37,000 in 2007. You might say this is interesting, except that 16% of those, according to U.K. statistics, wind up back on the national health service in the U.K. as a result of complications, in some cases quite serious ones. This trend hasn't hit Canada yet, but we look at all these things, because our services, as my colleague Patricia Fortier explained, have to keep evolving. We have to be where Canadians are and we have to be ready to help them when they get into situations as a result of what they've chosen to do.
