Yukon (; ; formerly called Yukon Territory and also referred to as the Yukon) is the smallest and westernmost of Canada's three territories. It also is the second-least populated province or territory in Canada, with a population of 43,964 as of March 2022. Whitehorse, the territorial capital, is the largest settlement in any of the three territories. Yukon was split from the North-West Territories in 1898 as the Yukon Territory. The federal government's Yukon Act, which received royal assent on March 27, 2002, established "Yukon" as the territory's official name, though Yukon Territory is also still popular in usage and Canada Post continues to use the territory's internationally approved postal abbreviation of YT. In 2021, territorial government policy was changed so that “The Yukon” would be recommended for use in official territorial government materials. Though officially bilingual (English and French), the Yukon government also recognizes First Nations languages. At , Yukon's Mount Logan, in Kluane National Park and Reserve, is the highest mountain in Canada and the second-highest on the North American continent (after Denali in the U.S. state of Alaska). Most of the Yukon has a subarctic climate, characterized by long, cold winters and brief, warm summers. The coastal area along the Arctic Ocean has a tundra climate. Notable rivers include the Yukon River as well as the Pelly, Stewart, Peel, White, Liard, and Tatshenshini rivers. Etymology The territory is named after the Yukon River, the longest river in Yukon. The name itself is from a contraction of the words in the Gwich'in phrase chųų gąįį han, which means white water river and refers to "the pale colour" of glacial runoff in the Yukon River. Geography The territory is the approximate shape of a right triangle, bordering the U.S. state of Alaska to the west and northwest for mostly along longitude 141° W, the Northwest Territories to the east and British Columbia to the south mostly along latitude 60° N. Its northern coast is on the Beaufort Sea. Its ragged eastern boundary mostly follows the divide between the Yukon Basin and the Mackenzie River drainage basin to the east in the Mackenzie mountains. Most of the territory is in the watershed of its namesake, the Yukon River. The southern Yukon is dotted with a large number of large, long and narrow glacier-fed alpine lakes, most of which flow into the Yukon River system. The larger lakes include Teslin Lake,
