From the publication:
"The Thunderchild First Nation live in North Battleford, Saskatchewan. On October 2, 2003, a settlement agreement was reached between the Thunderchild First Nation and the Government of Canada. The specific claim is based on events that took place during the 1908 surrenders of Indian Reserves (IR), 115,115A, 112A. The reserves were located on both sides of the North Saskatchewan River and North Battleford.
Nearly 80 years after the surrender, the Thunderchild First Nation submitted a specific claim in 1986 regarding the surrender of the reserves. According to the claim, the 1908 surrender was null and void. On July 9, 1993 the claim was finally accepted for negotiation. Ian Potter, Assistant Deputy Minister of the Department of Indian Affairs and Northern Development wrote a letter confirming the negotiation which stated that, 'For the purposes of negotiations, Canada accepts that the band has sufficiently established that Canada has a lawful obligation within the meaning of the Specific Claims Policy with regards to the 1908 surrender.' ”
Please read the rest of the publication to gain further understanding behind the claim.
