Thank you for the question.
We don't think we're duplicating or spending taxpayers' money inappropriately. We think there are some really compelling reasons to move as quickly as we can to deliver the Air Rail Link service.
I mentioned the five million people right now who every year drive between downtown Toronto and Pearson airport.
We also have the Pan Am games coming up. This is one of the only transportation commitments in the Pan Am games bid book that the levels of government endorsed in saying it would be in service in time for the Pan Am games.
So there are some important transportation benefits and some important governance reasons why we should be delivering the project.
That being said, we do need to look at the most effective way to deliver our rail services in an urban environment like the greater Toronto and Hamilton area in the future. That has implications not just for the GO rail service and the Air Rail Link service. That has implications for VIA and that has implications for the freight services. We need to make sure that we are going to be providing an environment in which all the different users of the same corridor can coexist.
We've come up with a concept at Metrolinx that we've called “express rail”, where we can actually move our GO transit service to a point where we can get frequencies up to about every five to ten minutes. You don't actually need to have a rail schedule any more to know when to go catch a train; you just go to the station. To accommodate that level of service, and the passenger ridership that will come with it, requires some significant investments in electrification.
