Yellowknife, NWT, incorporated as a city in 1970, population 19,569 (2016 c), 19,234 (2011 c). 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, 512 km from the Arctic Circle and approximately 1,513 km north of Edmonton, Alberta. 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.
