Interesting tidbit here, from the Inbox, thanks to Bill C in rural SK:
From the UN Declaration on the Rights of Indigenous Peoples:
1. Indigenous peoples have the right to the lands, territories and resources which they have traditionally owned, occupied or otherwise used or acquired.
2. Indigenous peoples have the right to own, use, develop and control the lands, territories and resources that they possess by reason of traditional ownership or other traditional occupation or use, as well as those which they have otherwise acquired.
3. States shall give legal recognition and protection to these lands, territories and resources. Such recognition shall be conducted with due respect to the customs, traditions and land tenure systems of the indigenous peoples concerned.
States shall establish and implement, in conjunction with indigenous peoples concerned, a fair, independent, impartial, open and transparent process, giving due recognition to indigenous peoples’ laws, traditions, customs and land tenure systems, to recognize and adjudicate the rights of indigenous peoples pertaining to their lands, territories and resources, including those which were traditionally owned or otherwise occupied or used. Indigenous peoples shall have the right to participate in this process.
1. Indigenous peoples have the right to determine and develop priorities and strategies for the development or use of their lands or territories and other resources.
2. States shall consult and cooperate in good faith with the indigenous peoples concerned through their own representative institutions in order to obtain their free and informed consent prior to the approval of any project affecting their lands or territories and other resources, particularly in connection with the development, utilization or exploitation of their mineral, water or other resources.
3. States shall provide effective mechanisms for just and fair redress for any such activities, and appropriate measures shall be taken to mitigate adverse environmental, economic, social, cultural or spiritual impact.
and here are some legal references from Cdn case law :
Haida Nation v. British Columbia (Minister of Forests),  3 S.C.R. 511,at para. 24:
The Court’s seminal decision in Delgamuukw, supra, at para. 168, in the context of a claim for title to land and resources, confirmed and expanded on the duty to consult, suggesting the content of the duty varied with the circumstances: from a minimum “duty to discuss important decisions” where the “breach is less serious or relatively minor”; through the “significantly deeper than mere consultation” that is required in “most cases”; to “full consent of [the] aboriginal nation … ” on very serious issues. These words apply as much to unresolved claims as to intrusions on settled claims.
And at para. 32:
The jurisprudence of this Court supports the view that the duty to consult and accommodate is part of a process of fair dealing and reconciliation that begins with the assertion of sovereignty and continues beyond formal claims resolution. Reconciliation is not a final legal remedy in the usual sense. Rather, it is a process flowing from rights guaranteed by s. 35(1) of the Constitution Act, 1982. This process of reconciliation flows from the Crown’s duty of honourable dealing toward Aboriginal peoples, which arises in turn from the Crown’s assertion of sovereignty over an Aboriginal people and de facto control of land and resources that were formerly in the control of that people. As stated in Mitchell v. M.N.R.,  1 S.C.R. 911, 2001 SCC 33, at para. 9, “[w]ith this assertion [sovereignty] arose an obligation to treat aboriginal peoples fairly and honourably, and to protect them from exploitation … ” (emphasis added).
Delgamuukw v. British Columbia,  3 S.C.R. 1010, para. 168:
The nature and scope of the duty of consultation will vary with the circumstances. In occasional cases, when the breach is less serious or relatively minor, it will be no more than a duty to discuss important decisions that will be taken with respect to lands held pursuant to aboriginal title. Of course, even in these rare cases when the minimum acceptable standard is consultation, this consultation must be in good faith, and with the intention of substantially addressing the concerns of the aboriginal peoples whose lands are at issue. In most cases, it will be significantly deeper than mere consultation. Some cases may even require the full consent of an aboriginal nation, particularly when provinces enact hunting and fishing regulations in relation to aboriginal lands.
