I don't have a deep understanding of it, but Unifor's position is that aboriginal treaty rights will necessitate a new approach to energy development that would include consultation and full socio-economic participation.
As a side note, I mean this is just like a footnote with my little name attached to it and not necessarily Unifor's, you can't cut people out of prosperity for the entire history of the country and have all the other injustices people have faced and then think that aboriginal people will be jumping on board energy development. No one in their right mind would do that. We need a new approach to energy development that recalibrates the relationship with first nations people.
On the UNDRIP, my understanding is that these declarations have no legal basis. The Canadian legal system would have to enshrine it in our domestic law for it to be enforceable.
