For those who want to read along, AC's international tariffs are here: https://www.aircanada.com/content/da..._Tariff_en.pdf

The relevant section is on page 93, RULE 80 – SCHEDULE IRREGULARITIES

The very first part of that section states


and that sets the tone

For the record, I think that AC is using the term "Schedule irregularity" as a broad term meaning everything from schedule changes, right the way through to irregular operations (irops).

The tariffs are broad (and very much in AC's favor) but I think they are reasonably clear.
