Located in Whitehorse, Yukon, the building is a three-storey white steel-clad structure.

Before relocating to Whitehorse, the legislature met at the Yukon Territorial Government Administration Building in Dawson City from 1907 to 1953 (now home to a satellite campus of Yukon University).

In 1976, the legislature moved to its current location in the new territorial administration building which was opened on May 25, by Jules Léger, the Governor-General of Canada.

The building houses most of Yukon Government's departments and is the home of the Legislature Assembly.
