While the claim is in the process of being prepared, we locate Colonial Correspondence, pre-emption records and Crown Grants, attached sketch maps, the Minutes of Decision for the allotment of the reserves, the schedules, the field books and all relevant survey plans as well as key archival documents and government and industry records. Critical to this process is a survey using the original Indian Reserve survey plan. A surveyor is hired to determine the size (acreage) of the alienated piece of reserve. The report is completed, approved by Chief and Council and handed to the lawyer for a legal opinion. It is then submitted to the Specific Claims Branch, a division of AANDC, for review by their staff and consideration by a Justice Canada lawyer. They must respond within a three year period as to whether they accept the claim for negotiation, or reject it.
