>interesting how this never came up in the Quebec referendums

It did come up. It's referenced in the Supreme Court of Canada case on secession. https://decisions.scc-csc.ca/scc-csc/scc-csc/en/item/1643/in...

"Consistent with this long tradition of respect for minorities, which is at least as old as Canada itself, the framers of the Constitution Act, 1982 included in s. 35 explicit protection for existing aboriginal and treaty rights, and in s. 25, a non-derogation clause in favour of the rights of aboriginal peoples. The "promise" of s. 35, as it was termed in R. v. Sparrow, [1990] 1 S.C.R. 1075, at p. 1083, recognized not only the ancient occupation of land by aboriginal peoples, but their contribution to the building of Canada, and the special commitments made to them by successive governments. The protection of these rights, so recently and arduously achieved, whether looked at in their own right or as part of the larger concern with minorities, reflects an important underlying constitutional value."
