You're right that the airport is governed under a tripartite agreement, which involves us, the City of Toronto and Transport Canada, representing the federal government.
Given that cities are governed under provincial jurisdiction, it is up to the province and the city to make the calculation as to who will be the representative. The reason there are three parties within that governance model is that, historically, there were some sandbars in that area, which our predecessor organization, the harbour commission, filled in. The sandbars were originally owned by the City of Toronto.
The land we filled in was and is owned by us. The representation is that about 78% of it is the Toronto Port Authority, 20% of it is the City of Toronto and about 2% of it is Transport Canada.
In terms of the obstacles, certainly they would have to work that out with the city directly.
