Well, I don't think it's fair to speak to that in the abstract. From my experience, when people have raised opposition, they've often done so because of concerns for water quality. They may be downstream from a development. Maybe they're indirectly impacted, but they will experience the impacts.
Again, I think the obligation on Canada is to find out what concerns are being raised, how indigenous peoples can be impacted, and what steps are necessary to ensure that all of their human rights are upheld in the process.
