Transit without visa is a great program. It's very limited in places today. There are other countries in Europe where people going from points east to points west do not require a visa to travel through an airport as they might if they were planning to stay. We currently do. We have a short list of places where you can transit through Canada without a visa. They have a short list of countries where you can't. It's been a good program. There have been very few abuses of the program or problems with it.
We're working actively with the government to expand it, but there's a lot of room for expansion. The program is currently limited to certain places in Asia for travellers going to the United States. Expanding in China could open up new routes, because it's restricted to certain cities. Ultimately, the goal is to have it international so we can take advantage of traffic between places like Brazil and Japan. If you're going from Asia to Latin America, or vice versa, you pretty much have to go through North America, so it's us or the Americans. If we can do things right, we can capture that market, and that would be a huge benefit for airports and air carriage.
