We did not in fact implement a no-fly zone over Ottawa.
What I said is that we put aircraft that were flying—we diverted directly over Ottawa—towards Ottawa initially to do a combat air patrol, an oversight, on top of the city of Ottawa, in case we had any indication that this was a complex network operation that would have used aircraft. Once we saw that there was no threat stream from the air, we diverted the aircraft to Trenton so they would be closer to the Toronto-Montreal corridor, including Ottawa, than when they regularly sit in Bagotville, as a preventive measure.
