I will answer you in English.
Part of the challenges, especially over the past summer, were in receiving health certifications for pilots from Transport Canada. There were significant delays, much longer delays than the average. What that meant essentially was that pilots were sitting around not able to work.
Another good example is any airline personnel who required access to sensitive areas of airports requiring a certification an RAIC. There were delays in getting those out as well. As a result, without those proper certifications, airline crews, including flight attendants, were not able to access airports and were therefore also not able to work. That was a contributing factor to some of the disruptions that we saw this summer. We hope that those delays won't be repeated in the future.
