Region of Waterloo International Airport - YKF

The financial reasons would likely stem from the schedule changes, considering the costs of pilots and airplanes are incredibly high, and shifting them around by an hour or more is of very real financial significance, let alone if it meant that upon landing up north, the entire schedule for their operations there also had to change, and/or if arrival later during the day up north compromised daylight landings.

Almost certainly not (imo).  But I doubt we can know either way.
