is here; their Manifesto:

The Treaties are nation to nation agreements between First Nations and the British Crown who are sovereign nations. The Treaties are agreements that cannot be altered or broken by one side of the two Nations. The spirit and intent of the Treaty agreements meant that First Nations peoples would share the land, but retain their inherent rights to lands and resources. Instead, First Nations have experienced a history of colonization which has resulted in outstanding land claims, lack of resources and unequal funding for services such as education and housing.

The state of Canada has become one of the wealthiest countries in the world by using the land and resources. Canadian mining, logging, oil and fishing companies are the most powerful in the world due to land and resources. Some of the poorest First Nations communities (such as Attawapiskat) have mines or other developments on their land but do not get a share of the profit. The taking of resources has left many lands and waters poisoned – the animals and plants are dying in many areas in Canada. We cannot live without the land and water. We have laws older than this colonial government about how to live with the land.

Currently, this government is trying to pass many laws so that reserve lands can also be bought and sold by big companies to get profit from resources. They are promising to share this time…Why would these promises be different from past promises? We will be left with nothing but poisoned water, land and air. This is an attempt to take away sovereignty and the inherent right to land and resources from First Nations peoples.

There are many examples of other countries moving towards sustainability, and we must demand sustainable development as well. We believe in healthy, just, equitable and sustainable communities and have a vision and plan of how to build them.

Please join us in creating this vision.
Not too many flames here - e.g., the strategy and tactics are vanilla Gene Sharp.

The basic political argument is "Indigenous Sovereignty", with a realization that that concept will not be easily accepted by the "Settler States":

...
Recognition, Exercise or Termination

It is well settled and clear that Settler States such as Canada, the United States, Australia and New Zealand would never voluntarily recognise Indigenous Sovereignty. Nevertheless, it is the recognition of sovereignty that permits for its undisputed exercise. How then is Indigenous sovereignty to gain recognition? Sovereign recognition embraces the notion of Nation to Nation relationship, one sovereign entity's interaction with another sovereign entity. This is most commonly seen through Treaty making and alliances of mutual benefit. The historic treaties Indigenous Nations have made with European nations bear witness to the nation - to - nation relationship. In a modern context of sovereign recognition, Indigenous Nations ought to continue to make treaties and alliances with other sovereign nations. This can be easily accomplished. For example, the Mohawk Nation could negotiate and enter Treaty of commerce and trade with the Mi'kmaq Nation or the Ojibway Nation entering alliances with the Cree Nation on environmental protection. The possibilities are endless and could and should include Indigenous Nations worldwide. The issue of Sovereign Recognition can be easily solved. ... (more fore and aft of this snip)
