I agree with Professor Cukier. It should be clear that there is no intent to infringe on first nations' hunting rights.
That being said, it should also be clear that military-style assault rifles should be more regulated if they are not, and should at least be registered in the name of the owner if, at the end of this process, they are still available in Canada. This is not an issue of discrimination. Australia doesn't have a special regime concerning firearm regulations for their first nations. I think it is important to apply the law to everyone.
