Unfortunately, we don't have systemic statistics, so I would be a bit hesitant to paint them with a broad brush. Surely, the fact that they are trying to fight the one-person-one-fare rule on international itineraries is a concern.
In another case I have been privy to, they took a passenger with disabilities to the Federal Court of Appeal in an attempt to overturn the Canadian Transportation Agency's decision, so they are being very combative in the cases I have seen when it comes to the rights of passengers with disabilities.
