We don't have specific projections on that. There are two points to make in terms of the agreement.
The agreement does provide for cost recovery for new pre-clearance operations, so the eight existing airports are protected from cost recovery unless there's some kind of extraordinary request for special services outside of the normal operating hours of pre-clearance operations. In terms of new sites, there are provisions for cost recovery. Similarly, if CBSA were to go to the U.S. and do pre-clearance, there would be cost recovery for operations.
Those discussions are happening now. They are site-specific, in terms of discussions between the U.S. and the individual pre-clearance sites for pre-clearance in Canada. But one of the pieces of work the Canadian government is doing is to work closely with the U.S. to ensure that we understand the framework for cost recovery that they're applying and to keep costs as low as possible for the traveller.
