Yukon is the westernmost of Canada's three territories. It was named after the Yukon River, Yukon meaning "Great River" in Gwich’in. A person from Yukon is called a Yukoner. The name Yukon Territory may also be used, although this usage is disputed by residents of the territory. The federal government's most recent update of the Yukon Act in 2003 confirmed Yukon, rather than Yukon Territory, as the current usage standard.
