Everything makes logical sense with details. Native populations through treaties have the right to hunt. Canada wanting to manage populations sets limits. This creates a lotto system. Winners sell them to big game US hunters and the tribe gets the profit.
The asbesto mines are in the French part of Canada which makes shutting them down politically difficult.
Canada is a collectiom of different people who figured out how to get along.
That said, I imagine neither country has a monopoly on such.

I do not see the harm in controlling the population via hunting instead of letting the populations teether wildly between the carnivores and herbivores as one of them gain dominance in the biosphere...
Also banning something outright just drives the people who want to do it underground where they can't be controlled.
