I need to answer a couple of things that you've raised there.
To your last point, we will be meeting with them in an ongoing effort to understand what their specific requirements are, how they may create a safety risk and, if that is a legitimate safety risk, what we can do about it.
Having said that, and because the issue of Seattle Boeing Field and Toulouse having control towers was raised, I should tell you that you'll see from the information before you that Seattle Boeing Field has 300,000 movements a year and Toulouse has 94,000 movements a year. Under those circumstances, they would certainly have control towers in Canada if they had movements like that as well.
The issue of the $500,000 goes back to the basic equity of how we work and the requirement for us to apply our level of service policy. It's a legal requirement to apply it in a consistent fashion. Right now the cost of putting a tower back in Mirabel would in fact end up being borne and paid for by people who do not serve Mirabel. That is the basic fact. In Canada we have a national policy of assessing terminal charges, and that's for good reason: if we didn't, we would end up with the major centres--the Montreals, the Torontos, the Vancouvers--having very low costs assessed to the operators of the airplanes, while the people in the smaller centres--the Kelownas, the Fort McMurrays, the Val d'Ors--would be paying amounts that could be 10 or 20 times as much. For that reason, we have a national policy of assessing the terminal charges, which means we are making everybody pay for every unnecessary dollar that we spend in an airport.
It's also why I come back to one possible solution in this issue. Since it is a very specific group of companies that is asking for the return of the control service, there's a simple way to do it. If they will pay for it--and I don't think it's a lot of money for companies of that size--then we can avoid all that problem. We'd be more than happy to put it back, but we do have a legal obligation not to discriminate in terms of the application of our level of service policies, and it's for good reasons.
