The Yukon formerly called Yukon Territory and sometimes referred to as just Yukon is the smallest and westernmost of Canada’s three territories. It also is the least populated province or territory in Canada, with a population of 35,874 people as of the 2016 Census. 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. 

To align with actual use by Yukoners, the territorial government determined in 2021 The Yukon, with the article, to be the recommended name to use in territorial government materials. However, for financial reasons, existing websites, signs, documents and other government materials will not be updated until they have to be changed anyway.

Though officially bilingual (English and French), the Yukon government also recognizes First Nations languages.

At 5,959 m (19,551 ft), 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 Arctic Ocean coast has a tundra climate.

Notable rivers include the Yukon River as well as the Pelly, Stewart, Peel, White, and Tatshenshini rivers.

Climate

While the average winter temperature in the Yukon is mild by Canadian arctic standards, no other place in North America gets as cold as the Yukon during extreme cold snaps. The temperature has dropped down to −60 °C (−76 °F) three times, 1947, 1952, and 1968. The most extreme cold snap occurred in February 1947 when the abandoned town of Snag dropped down to −63.0 °C (−81.4 °F).

Unlike most of Canada where the most extreme heat waves occur in July, August, and even September, the Yukon’s extreme heat tends to occur in June and even May. The Yukon has recorded 36 °C (97 °F) three times. The first time was in June 1969 when Mayo recorded a temperature of 36.1 °C (97 °F). 

14 years later this record was almost beaten when Forty Mile recorded 36 °C (97 °F) in May 1983. The old record was finally broken 21 years later in June 2004 when the Mayo Road weather station, located just northwest of Whitehorse, recorded a temperature of 36.5 °C (97.7 °F).
