Indeed, in Canada, the political system and the Canadian Transportation Agency appear to favour carriers at the expense of consumers. And, it's taken a long time to address the issue, whereas in other countries it was done at the beginning of the crisis.
There is also a difference in the way the Air Passenger Protection Regulations are interpreted. As the name implies, these are regulations that should protect consumers. The numbers prove how necessary the regulations were. Since they was put in place on December 19, 2019, there have been 22,000 complaints. Half of them were filed before the crisis, so within the first three months after the regulation was put in place.
If regulations that are designed to protect passengers generates so many complaints, questions may be raised about their merits and enforcement. If you have the power to ignore it when passengers need it, it's just as problematic.
