I'm speaking of the U.S., not Canada. I have no say in how you solve your problems, nor want any. Just friendly interest and good wishes.
Speaking for myself alone, and not for any nation, tribe, band, or organisation, what it will take is full legal equality and non-discrimination.
Including no "favourable" discrimination.
We were horribly abused. Tough ****. Many have been. We were slaughtered in our millions. Tough ****. Many have been. Our cultures and ways were overwhelmed and debased. Tough ****. Many have been.
The "sovereign" reservations, the special programs, the Bureau of Indian Affairs, the Indian Health Service, the Indian Gaming Act, &c. all serve only to set us apart. Most programs are ridiculously underfunded, and eligibility for them excludes us from eligibility for equivalent programs for Shemanese that are much better funded.
Do away with the reservations. Break 'em up and allocate the land, once and for all. Do away with all Indian programs. Do away with the sick dependency of Indians on the charity of the Shemanese.
Then we will either die off, or get a grip, get education, get jobs, build wealth and power. Then, if we want, we can take over a county and pass Indian-friendly county ordinances (within the confines of state law). Maybe we can even take over a state and pass Indian-friendly state laws (within the confines of the Constitution and Federal laws). Then we'll be Indian because we choose to be, not because the Shemanese have decided (again!) "what's good for us."
