I would just say that the TPP as it currently reads would not bring the kind of benefit, in my opinion, to first nations that's being talked about here. Canada's only specific mention is on the procurement policy, and that's where indigenous peoples tend to be relegated, jobs and training, beads and trinkets. We're talking about ownership of our own lands and resources, which are in the billions and trillions of dollars.
You give me my lands and resources, and I'll train and contract with my own people. That's part of the problem. We're not protecting the benefits, or the environment, or the devastating impacts that will happen with other people extracting from our industries. Part of the problem here is that this can be addressed. New Zealand did manage to get a substantive amendment, after the TPP had closed, on intellectual property rights for traditional Maori plants and medicines that were important to them. There's no reason that Canada can't argue for the same.
UNDRIP alone requires free, informed, and prior consent, and you don't have it. UNDRIP has already been violated, as have numerous other international instruments. Our own Constitution has been violated. We haven't even been informed or consulted yet. We haven't even had the basic minimum of the consultation process.
There are significant legal problems, very limited potential benefits, and a great potential for harm for indigenous peoples and Canadians alike.
