This foundation has led to other important agreements, including the Sanarrutik Partnership Agreement and the Peace of the Braves, both massive economic development agreements that make Inuit and Cree partners in decision-making and benefit sharing. However, more than thirty modifier agreements, ancillary agreements and relevant laws illustrate the complex and dynamic nature of the Agreement. In 1984, the Canadian Parliament kept its promise of Aboriginal autonomy and adopted the Cree-Naskapi (Quebec), the first of its kind in the country (see Indigenous Self-Government in Canada). Naskapi joined the JBNQA in 1978 by signing the Northeast Accord of Quebec. The following year, the Quebec government negotiated the necessary agreement. On November 15, 1974 – exactly one year after the Supreme Court`s decision – an agreement in principle was signed between the governments of Canada, Quebec, Hydro-Québec`s public property, the Grand Council of Crees, led by Billy Diamond and the Inuit Association of Northern Quebec.  The final agreement – the James Bay And Northern Quebec Agreement – was signed on November 11, 1975. This agreement initially extended only to the claims of Quebec Cree and the Inuit; On January 31, 1978, the Naskapi of Quebec signed a parallel agreement – the Northeast Quebec Agreement – and joined the institutions created under the 1975 Agreement. Significant difficulties hampered a definitive solution between the Cree, the Inuit and the Quebec government.
For example, the IQA, which represented Quebec`s other Aboriginal nations in the negotiations, demanded full payment of land rights across the province. The relationship between the Cree and the IQA deteriorated until the Cree detached themselves from the organization and formed their own national network: the Grand Council of Crees of Quebec. In the summer of 1974, the IQA left the negotiating table and the province, Cree and Inuit reached an interim agreement.
