Thank you for that.
Turning now to Mr. Morrison, I find the issue of airport rent an interesting one. You've said you support the user-pay philosophy. Other witnesses we've had have been less supportive.
If you support the user-pay philosophy, isn't paying for rent part of that? The airports are set up as stand-alone financial entities. The land doesn't belong to the airport authority, so if the land was to be provided for free or if the money was going to be given back, to me, that looks like a public subsidy.
