Description: From report provided by Anita Lemmetty:1. Introduction The Northwest Territories Lands and Resources Devolution Agreement-in-Principle (AiP) was signed on 26 January 2011. Section 5.13 of this Agreement required the determination of a Line of Delimitation in the Mackenzie River Delta, ‘to reflect the ambulatory nature of sections of the coast…allowing for the inclusion of Small Enclosed Bays and approximating the low-water line of the coast’. A delineation working group was formed, pursuant to section 5.15 of the AiP. Natural Resources Canada, Surveyor General Branch (SGB) was engaged by Aboriginal Affairs and Northern Development Canada to support this working group by preparing maps for discussion purposes and ultimately, the description of the agreed upon Line of Delimitation. The final Devolution Agreement was signed in Inuvik on 25 June 2013; the corresponding legislation is scheduled to be proclaimed in April 2014. 2. Map Preparation An initial line was presented, closing off the mouths of small bays that met the definition of ‘Small Enclosed Bays’ as per the AiP and following the coastline extracted from the Canvec 8.0 dataset. As the available imagery of the area of interest was inconsistent in quality, scale, and date, it was decided that updated imagery should be obtained to better assess the existing landforms in the area. The Radarsat-2 satellite was subsequently tasked by SGB to acquire the imagery during August and September 2012. Once all of the processed imagery was received, it was imported into the working maps and used as the backdrop for the Line of Delimitation. As the discussions progressed, two criteria were selected for the line. It was decided that for ease of splitting the existing oil and gas interests in the area, the original line would be approximated by a line defined by the boundaries of the oil and gas units of the theoretical oil and gas grid areas defined in the Canada Oil and Gas Land Regulations (C.R.C. c. 1518); the line was to be as close as possible to the coastline, but consistently offshore throughout. Secondly, where Inuvialuit Final Agreement (IFA) 7(1)a lands extended to the coast, the line would transition from the oil and gas grid to follow the shoreline of the IFA 7(1)a lands to avoid leaving a small strip of land between the shoreline, described as the ‘mean or ordinary high water mark’ in the IFA Agreement, and the ‘low-water line’ called for in the AiP. Two minor exceptions to these criteria were made: to accommodate the transition from the oil and gas grid to the Inuvik 7(1)a lands, a section of coastal Inuvik 7(1)b land was followed, and; to include the Tuktoyaktuk community lands, the line transitioned from the Tuktoyaktuk 7(1)a lands to the oil and gas grid. To best support the description of the Line of Delimitation and ensure consistency, a fifteen sheet map was prepared under Section 31 of the Canada Lands Surveys Act and recorded in the Canada Lands Surveys Records as 101827 C.L.S.R. 3. Preparation of Description The following points were considered during the preparation of the description of the Line of Delimitation: -As the Yukon Territory is described as being bounded ‘on the north, by that part of the Arctic Ocean called Beaufort Sea’, the point of commencement for the line was selected as the intersection of the Yukon/Northwest Territories boundary or the prolongation thereof, with the oil and gas unit boundary closest to the shore(but not onshore), as determined from the Radarsat-2 imagery.-In order to maintain consistency with the lnuvialuit Final Agreement (IFA) parceldescriptions, the NAD27 coordinate values for the IFA parcel corners listed in the IFA are identified in both the description and map as being NAD27.-It was acknowledged that under the Canada Oil and Gas Land Regulations (C.R.C.c. 1518), a number of grid areas may have been ‘fixed’ by survey; for greater certainty, the line is intended to follow only the theoretical grid as described in the regulations.-Clause 17 and 18 address the transition from the 60 section grid area to the 100 section grid area that is visible as a slight deflection between the respective western unit boundaries on Map Sheet # 7.Signed in Yellowknife, NTCertified CorrectDavid S.
