You might still be figuring it out after reading this since while it's true that Canada's Constitution does not (& can't) recognize Indigenous sovereignty, Bill C-15 doesn't give Sec.35 of the Constitution (or any Canadian law) any power it doesn't already have (& already use). https://twitter.com/volc8o/status/1388279284381282307

UNDRIP can already be interpreted through Canada's courts without Bill C-15 (which it expressly allows for). And UNDRIP is not the "legal basis for Indigenous sovereignty against the colonial power of nation states," Indigenous sovereignty is the basis for UNDRIP.

UNDRIP is not a treaty/convention/law but a set of standards that can apply to law. The UN points out that free, prior & informed consent was already present in various actual legally binding UN treaties prior to UNDRIP, it is merely re-affirmed (in stronger wording) in UNDRIP.

In practice, Canada fights against Indigenous sovereignty on the ground & ignores various facets of various UN treaties that are meant to protect Indigenous rights (& even reprimands from UN committees, like in the case of the Unist'ot'en Camp & healing centre).

The main problem with Bill C-15 is that it's a smokescreen. The collaboration with neo-colonial organizations like the AFN, rather than grassroots people is of course a problem, but it's far from new or exclusive to Bill C-15.

Readers might also end up confused when they figure out that vaunted Supreme Court of Canada Aboriginal title wins like Tsilhqot’in Nation v. British Columbia, 2014, and Delgamuukw v. British Columbia, 1997, also operate under Sec.35 of the Constitution & Doctrine of Discovery.
