Again I would say it's a problem that we have not encountered, but if we were to encounter that problem, I think there are two principles that would be at play. The first is that Transport Canada would defer to the owner of the airport—in this case it's usually a provincial or territorial government—because they are the ones who are accountable and responsible. However, Transport Canada would demand a minimum level of safety. We've actually had this problem with some small airports. Sometimes it's cutting the trees. There are a number of safety requirements that are absolutely non-negotiable. If an aerodrome is not adhering to those, Transport Canada safety and security inspectors will come in and will take regulatory action under the Aeronautics Act to ensure that happens. An example would be that sometimes we have issues with aerodromes—less in Nunavut—in the south where trees grow on the approach and the aerodrome has to keep the trees cut because of the risk of a plane hitting the trees when it's trying to land.
There are certain things like that on which we will be completely inflexible, because they have to do with the safety of Canadians. Beyond that, we'll work with the owner of the airport on their priorities and try to support them in implementing their priorities both to safely operate the aerodrome and to increase the capacity to meet the needs of the members of their community.
