It doesn't deal with much more than that.
Do we know what's meant by changes? Is it just expansions or would it include refurbishing runways? I don't think it would cover changing flight paths, because that's taken care of by Nav Canada. I doubt it has anything to do with the so-called curfews. Basically, is it changes to the physical airport, including or not including the building of a runway, for example, on land that already belongs to the airport?
