The chart on the right shows the information graphically, with the most recent elections on the right (going as far back as the introduction of political parties in 1978). The Yukon Party (which was named the Yukon Progressive Conservative Party prior to 1992) has been the most successful since political parties were officially recognised, having won five out of nine elections. The NDP have won three elections, and the Liberal party have won one election.
The table below shows the total number of seats won by the major political parties at each election. It also shows the percentage of the vote obtained by the major political parties at each election. The winning party's total's are shown in bold. There has been only one election (in 1985) where the party that formed the government did not have the largest share of the vote. Full details on any election are linked via the year of the election at the start of the row.
There were no territorial parties in the Yukon before 1978. From the territory's creation in 1898 until 1978, the Yukon was governed by a federally appointed Commissioner advised by the Territorial Council. The Territorial council was wholly appointed from 1898 to 1900; part elected, part appointed from 1900 to 1908; and wholly elected from 1909 to 1978.
The number of members varied considerably during the council's 80-year history. The 1900 election elected just two out of eight members; the elections from 1903 to 1907 elected five out of ten members. The wholly elected Council comprised ten members from 1909, which was reduced to three from the 1920 election. This was increased to five from the 1952 election, seven from the 1961 election, and twelve for the final general election to the Council in 1974.
