I don't have all the details. All I know is that the Maori obviously were involved a lot earlier on, although probably not as early as they should have been or New Zealand wouldn't have been arguing after the fact for intellectual property rights for plants for Maori. However, they did successfully get in the treaty exemption provision, which is under the exceptions part of the TPP; whereas under the TPP all Canada has is something on government procurement, which is no more than what they've also set aside for regular Canadians.
There's nothing indigenous specific to the procurement process, but it doesn't mention aboriginal and treaty rights. Again, for legal interpretation they would say you specifically identified indigenous people for procurement, but not for aboriginal and treaty rights, so the presumption will be you didn't intend to include it. While that was the doing of the previous government, this government really needed to step up right away and get indigenous peoples together and ask what can be done about this, if anything, to save it, and it hasn't. Now we're at a point where it has to be a no. There's no way to save this legally.
