I think the confusing part is that the word "soverignty" isn't normally used to describe things like that.

Cities aren't normally "soverign". Soverignty traditionally implies absolute control of a piece of land, independent foreign policy/military, a seat at the UN, etc. That is quite different than limited self-government or even an atonomous territory.

I don't think the traditional type of soverignty is the type of soverignty first nations are seeking. If it were, i imagine Canada gov wouldn't exactly be cool with it.
