I think a few people in Canada - including the occasional poster - could benefit from an improved understanding of the history of Canada and how the current colonial system of laws was imposed upon already functioning hereditary governance systems - and how that affects the laws and the regulations that are developed from those laws.
In short - FNs are not a "special interest" that the occasional poster have claimed - but rather existing Rights and Title Holders of unceded territories (esp. in the West and BC) that were invaded and colonized by primarily European settlers starting on the East Coast and working their way West.
In that process of colonization -
terra nullius as espoused 1st by the Catholic Church and the Pope (
http://longmarchtorome.com/terra-nullius/)- was that assertion that South America was "empty of people" - the term "people" only being reserved for pope-abiding Catholics and not the existing "savages" whom already had often quite developed hereditary governance systems & civilizations - and the Catholic conquistadors did pretty much what they wanted wrt genocide, slavery and domination. That was the 1st "racist" law imposed upon "new" world aboriginals.
In North America - it was different. 1st came limited and small-scale European settlements that were originally supposed to stop (and not expand West of the Appalachians:
https://history.state.gov/milestones/1750-1775/proclamation-line-1763 ) as colonies on the East Coast of "New England" - where numerous treaties were signed and sometimes fulfilled in part or in whole since the settlers knew they needed allies and generally ratified through the The Royal Proclamation of 1763 (
http://www.history.ubc.ca/sites/default/files/courses/lectures/[realname]/3bb_terra_nullius.pdf). The assertion of British sovereignty was thus expressly recognized as
not depriving the aboriginal people of Canada of their pre‑existing rights; the maxim of
terra nullius was
not to govern here.
The Royal Proclamation of 1763 is every much as important and legally binding as say the Constitution Act (both original and 1982 revised versions) - the same Act that all our laws generate their authority from.
But then came figures such as Edward Cornwallis (
https://www.rnshs.ca/wp-content/uploads/2018/02/RNSHS_ThreeLivesEdwardCornwallis_JohnGReid_2013.pdf) in the East - and during the westward expansion came Joesph Truth (
https://en.wikipedia.org/wiki/Joseph_Trutch) and left quite a mess in their wake - not to mention the Indian Act of 1876.
Lots more history - but lets skip forward to the Repatriation of the Constitution of 1982 and s.35 -
The existing aboriginal and treaty rights of the aboriginal people in Canada are hereby recognized and affirmed.
From that seemly insignificant reference in 1982 - quite a bit of case law has been generated that further refines and expands how the Government of Canada is supposed to deal with aboriginal Rights and Title and consultation and accommodation.
