In terms of starting earlier, we started very shortly after the request came in. Given what's called “ramp space” and “slots”, the number of slots that we could have for Canada limited the number of flights that we could put in.
In terms of staying longer, the deteriorating security situation on the ground, the fact that our allies, namely the U.S., were withdrawing on August 30 meant that we had to cease evacuation operations on August 26 because after that date the focus was on reducing the security perimeter around Kabul International Airport.
You have to realize that the perimeter around that airfield was 14 or 15 kilometres and took a sizable force to be able to secure. It was a very dangerous operation to collapse a security perimeter while surrounded and ensure the safety and security of our own forces and get them out. Let me just say, you don't want to be the last flight out of there when there's no security perimeter in place.
The 26th was the last day that we could, in conjunction with our allies, conduct evacuation operations. In fact, we did get some Afghans out on the 27th, but that was due to some low-level coordination. That was the reality on the ground.
