I would make a few observations here.
You're right about deregulation. The ability of government to directly control everything has been reduced, and the marketplace is now much more dominant than it was back in the sixties and seventies.
Having said that, one of the things that I think government still has significant influence over is setting the broad conditions within which all of these private sector players play. One of the things we have not been able to do—and I think this is a challenge for government in the next few years—is make sure that this framework leads to the optimization of the various modes, so that the various modes of transport, whether they're freight or passenger, are playing their most efficient role in the overall system.
One of the prices we're paying because we haven't been able to do this is the massive increase in greenhouse gases because we are not using the right modes to do the right things in the system. We're contributing much more greenhouse gas to the system than we should be.
Through the combination of an environmental policy and policies that are unfolding now, such as gateway policies, concerning which I would argue that the government's leadership on the west coast has made a significant difference—it's certainly not perfect, but it has made a significant difference, and people are now being more rational, in their modal choices out there, than they were in the past—there are ways to move in that direction.
You mentioned air specifically. You're absolutely right: if there were a high-speed rail system between Montreal and Toronto, it is highly likely that people would opt for that service rather than take a cab out to Pearson and fly to Dorval, then take a cab from Dorval to wherever they're going. But that's not Air Canada's long-term future. I'm not a spokesperson for Air Canada, but when I look at the kinds of airplanes they own and the kinds of networks they have around the world, their long-term future is long-haul international or North American air service.
Now, for Porter Airways it's a different matter, and Jazz, in those particular markets, could very well be hurt from a business point of view; I don't argue the point. But in the broader public policy context, companies have to adjust to the reality of the competition they face. And they will adjust. I don't see Canada's bus companies going out of business because of high-speed rail. They will have to serve the nodes, down to wherever you can connect into that system, from all over small-town Canada, in the areas where these kinds of services are going to be available.
