The AC YQT-YWG segment has been in a descending spiral for many years, matched by WJ ascending. YQT-YWG was 2x daily 15 years ago, then 1x daily on a CRJ2, then 1x daily on a Q4, then 1x daily on a Dash3, with terrible sched. At some point in the early 2000s the segment was operated by Calm Air.

Interesting how WJ could manage a 6am start and 25mins connections in YWG (or continue direct to YYC in the 737 days) while AC would start at 5am to feed marginally earlier departing YWG flights.

AC choose not to be competitive on this segment; no surprise it eventually failed.
