This agreement affirms the Métis right of self-government and recognize the mandates of the Métis Nation of Saskatchewan (and Métis Nation of BC and Métis Nation of Alberta). The agreement also set out next steps to formally recognize the Métis governments as Indigenous governments in Canadian law.

While the Métis Nation of Saskatchewan already has well-established province-wide governance structures, the agreements signed today deal with the recognition of Métis jurisdiction in core governance areas (citizenship, leadership selection and government operations). They also set out processes for negotiating other agreements dealing with additional areas of jurisdiction in the future.
