Yellowknife, Northwest Territories, incorporated as a city in 1970, population 19,569 (2016 census), 19,234 (2011 census). The city of Yellowknife is the capital of the Northwest Territories and the territory's only city. It sits on the Canadian Shield, on the north shore of Great Slave Lake, and about 400 km south of the Arctic Circle. Due to its northerly location, Yellowknife is the Canadian city with the most hours of summer sunshine, averaging 1,030 hours per year. The city and Yellowknife Bay were named after the Yellowknives, a Dene band who lived on the islands of Great Slave's East Arm and travelled as far north as the Arctic coast to obtain copper for knives and other implements. They, in turn, acquired their name from the copper-bladed knives they carried.
