To get started in terms of construction? As I said, we just launched the update of those studies. The situation has evolved considerably since 1992-1995. We have more population in the corridor than we did before. The technology options have evolved significantly. As well, there are changes in the other modes. If you recall at that time, we had a slightly different airline structure than we do today, and people, I think, are changing their attitudes. We know Canadians are still highly dependent on automobiles, and that's probably the mode of preference, but I think more and more we're seeing a shift toward greater use of public transportation, whether it's urban transit or rail. Even VIA has been experiencing a little bit of growth on its passenger rail services.
So we need to make sure we are current in these studies. This would be a huge undertaking, and we want to make sure we're looking at everything that needs to be looked at.
