If I could add briefly to what Denis just said, it's exactly that. We've seen that all airports and all agencies around the world have been struggling to adjust to this big increase in traffic. The sharp increase in Canada has CBSA struggling to adjust. They've had some amazing progress at Pearson, and we now have the customs hall at Pearson flowing much better than it was a month or two ago.
CBP and the pre-clearance in Montreal and Toronto.... There are some issues with backups, particularly in early morning flights going out of those two airports into the U.S., in terms of the CBP's processing capacity. You see that it has even affected the CATSA numbers in Toronto and Montreal. The longest waits you see at CATSA are actually for those pre-clearance lines, because CATSA has to slow down to avoid putting too many people into the waiting room of the U.S. CBP.
We are working with our American counterparts and colleagues. They're engaged with us, and we're working together to seek solutions so we can get the throughput through CBP and the pre-clearance in Toronto and Montreal higher, consistent with the demand to travel between Canada and the U.S.
