The agreement in 1992, when the operation of the airports was transferred to local airport authorities, was that the federal government didn't have the money to upgrade the value of the asset, so that you would take it, you would upgrade it, and for the privilege of operating it and paying for the upgrades. “Oh, by the way, you're paying us airport rent.” Over time, the airport authorities looked at it and said, we have a gun to our head here, which was: either take it the way it is and upgrade it, or else you ain't getting it and you won't be able to operate it on behalf of your community—and you have to pay us rent.
They took the rent deal early on, and the lease, the legal document that exists for the airport authority that operates the airport, is between the airport authority and Transport Canada. That legal document, that type of lease, has changed. The first four that went—Vancouver, Calgary, Edmonton, and Montreal—have what was called a local airport authority lease. They eventually became Canada airport authority leases, over time.
Right now we have a changing business environment. At the time of transfer, airports were being operated very differently from how they are today. Airport authorities operate a business. They market the community in the same way as a local tourist destination does, or anything else. We ourselves, even CAC, market Canada, believe it or not.
