They exist. Use them to read about situations like the Dakota pipeline protests and stop only looking for examples to back up your (highly incorrect) theory.

The government isn't legitimate. They commit all sorts of treason on a daily basis, and then do their best to hide it under the guise of "national security". They became just another organized crime cartel messed up with the mob, and the communists as did Hollywood over half a century ago. China pretty much owns them all now.

How would you like the government to decide without any civil litigation that you don't really own your land, then bulldoze your house to the ground, turn it into a parking lot, throw you out on the street, and without any compensation since it wasn't your land by their own summary judgement? Or are you just being racist towards indigenous people?

While litigation is still taking place and no claim has been awarded nothing is going to move. Once a claim is settled then you could have an "eminent domain" where the party that was awarded the claim can then be fairly compensated for the use of their land.

I think the question of if we have a legit government is a good one for discussion and maybe for the courts. The Liberals broke many promises in their seeming quest to please North American oil companies in a sunset industry instead of building a new "green economy". Imagine wrecking the land and marine environments and the climate for 2 - 5000 temporary jobs to sell unrefined resources to a region with a very long history of legally and illegally undermining North American jobs and lifestyles. Does not sound like a legit government to me.

I'm wondering if we need First Nation reps in all Trade Agreements to make sure Federal Governments don't sell us out.
The OP can move to China with his gas mask or move to the US and fly back for his health care.

By "shed" you mean pipeline. Indigenous people in Canada, for now, have some say in what gets built in their land; at least according to the Supreme Court of the land. Judging by what happened with the Dakota Access pipeline in the U.S. not so much for indigenous people there.

If you actually care about this and want sincerely to get to the bottom of it, you need to educate yourself. Go to the library and read Thomas King's "Inconvenient Indian." Or just go on Wikipedia and look up "numbered treaties."

Spoiler alert: white people have been deceitful, treacherous pricks for a very long time and it's only been since the Truth and Reconciliation Commission 10 years ago that some people have tried making things right. Yes, this might mean putting the brakes on projects that could make someone some money but that's only so we can make sure First Nations folks have a say in how things happen. Democracy is slow. Fascism is fast.

It's a shame you cannot see what absolute heroes the First Nations have been for us in this fight. They are protecting all of us by fighting Kinder Morgan and while we will all benefit from the outcome, they are fronting most of the legal expense and ending up in confrontations with police.
If you are so out of touch to believe other countries do not have these issues, research Standing Rock, where the American government brought in snipers to shoot people for protecting their own land. I dont think China has a cleaner history either.
Count your blessings you live in a country that will recognize and respect our human rights enough not to kill us for protesting and have some respect for the people putting their everything on the line so you can have a clean place to live.

They lose that right if their culture is conquered or if they lose a war.
See any of the Scots going back home and claiming their dispossessed farmlands?

According to the Federal Court of the land. The Supreme Court has yet to weigh in on this issue. You never know. The Federal Court ruling may still be the only victory the "No Pipeline" side scores in this dispute.

Why would Thomas King's version of events be any more reliable than my own?
Even the title suggests a borrowing from that piece of trash by Al Gore, plus he's bound to write with bias because he's part Native Indian himself.
As for treaties I suggest you, yourself go to the history books and see how many have been torn up before the ink is dry.
Treaties are worthless once the Government changes or once they no longer serve the purpose of one ( or any) of the parties.
As for reading something, well I don't think there can be too many people more well read on this subject than myself, but my "well read" doesn't have the same cultural origins as your "well read",creating a gulf that can't be crossed
