Actually, the tax varies based on whether the flights are international or national. We could discuss that further.
In the case of NAV CANADA, it is responsible for the safe control of Canadian airspace. That is its job, its responsibility. At one time it belonged to Transport Canada. We were responsible for regulating it. To regulate an organization that already belongs to us is not a good thing. That kind of independence is necessary.
Having said that, I want to point out that NAV CANADA is recognized worldwide for the quality of its work when it comes to air traffic control.
