And like with other problems, if it was simple and easy to do, it would have been done long ago simply and easily.
Yes. What I wrote is just my usual this-is-the-way-it-ought-to-be, based on the aspiration of one class of citizenship and the notion that neither citizens by birth nor naturalization are obligated to pay rent to people who happened to live on or near a particular piece of ground at a particular point in time. The rentiers and their layers of advocates would be losers, and all the people locked into living in particular places with particular lacks of opportunity would be winners.
In your fed-prov-muni model, since municipalities tend to be "creatures" of the province (exist by way of provincial legislation), will provinces now take the lead in dealing with First Nations?
Yes, but the "dealing" would be no different than the relationship between the province and municipal councils and mayors.
How will FNs feel about that?
Probably some would hate it. The fiction of a nation-to-nation relationship with a G7 country is attractive, but absurd for groups of a few hundred or even tens of thousands. The entire edifice is a colonial hack suitable for maintaining peaceful relations between locals and chartered monopoly trading companies which really, really needs to be modernized.
How will the provinces feel about that?
No idea. But they're already stepping in to provide some services. Either the government of Canada should be covering everything, or the provinces.
And the Treaties signed by the Queen's reps of the time - toss those, or start from scratch? I'm going to guess starting from scratch, with both sides well lawyered up with a ton of legal decisions in place (at least generally) supporting the Indigenous claims most times they've come up, it could mean a ton more $ from Team Fed at least.
Some groups have already settled and moved on, and some have not. There'd have to be some sort of initial startup funding to set up municipal governance and establish boundaries within which munipalities have powers of taxation. Some of the existing lands would have to be trimmed and revert to crown land. After that, municipalities are either viable - meaning, they have a commerce and tax base and customary provincial funding which can support a community of whatever size they are - or they're not. Those which are not revert to whatever the status is of all the small communities without self-governance.
Yeah, having federal legislation in place since time immemorial has painted both sides into a corner, with add-on's here & there trying for better solutions, but leading to a messier shack. Don't know the answer, only that it ain't going to be easy.
It isn't merely difficult; it's essentially impossible. There won't be a negotiated solution to "one status of citizenship". What's unforeseeable is the alternative - what eventually happens when all the people taxed by governments with immoderate spending appetites are fiscally pressured beyond reasonable tolerance and start asking hard questions about hereditary privileges? (They won't care about the hereditary obligations, which often enough are sufficiently harmful that their input won't be needed to get the obligations trimmed.)
