This might be for Mr. Burt, but anyone can jump in.
You mentioned earlier that our top threat currently is probably an asymmetric one, so terrorism probably represents our biggest challenge. Thinking of the western part of Canada, would you agree—without giving us a specific threat assessment—that from Winnipeg west, let's say, there would be a higher probability of an incident occurring in the Vancouver area, more often than not, just given the volume and diversity of air traffic going in and out of Vancouver? Would you say that's a fair statement?
