In December 2019, Transport Canada changed the flight duty fatigue regulations. This was largely to counter some of the major airlines that were not counting the time of deadheading pilots, which means the time they're on board as passengers going to their destinations to start their flying. I know that we, Canadian North and most of the other airlines in Canada, do count the duty day as soon as that pilot reports.
Unfortunately, the change in that policy has had a devastating effect on the amount of time we have to fly every day. It often means that you can't do a second flight; you won't have enough duty day time for it. Also, if there's a delay because of fog or weather in the morning, the pilots, because of that delay, often don't have a chance to do a trip to a lot of our high Arctic communities.
For us, that cost has been substantial. When we look through our network, it's in the neighbourhood of 15% on our flight operation costs already. Therefore, it's a substantial increase due to that policy change.
