TNO; Athapascan languages: Denendeh; Inuvialuk: Nunatsiaq; Inuktitut: ᓄᓇᑦᓯᐊᖅ) is a federal territory of Canada. At a land area of approximately 1,144,000 km2 (442,000 sq mi) and a 2016 census population of 41,786, it is the second-largest and the most populous of the three territories in Northern Canada.
