Since I don't work directly in the communities, I can't really speak to the impact of negotiated agreements.
However, at another time, I worked for Quebec Native Women, and I can tell you that this organization was created to give indigenous women a voice.
The scope of consultations could certainly be broadened so that they aren't limited to band councils. Other parties and community members who will be affected should also be contacted. It's also important to remember that the issue is even broader and that urban indigenous people are also affected by developments in the communities.
