In our case, I think one of the biggest was the signing of the first blue skies arrangement with the United States in the 1990s. That has had a tremendous impact. Before that point, the only cities in the U.S. that were accessible were cities that had major customs/immigration points in the United States. When they redeployed customs agents, when they put in the pre-clearance arrangements, when they expanded that arrangement in Canada and it went to Halifax—Mr. Staples talked about it a moment ago—it had a huge impact on growth.
There's a good indication that facilitating and finding a way to make it easier for people to travel through places actually has a great benefit, and it expands very quickly. We saw it in Montreal, and the most recent example is Halifax 10 years ago.
