In January 2009 the NDP were reduced to two seats: Todd Hardy (Whitehorse Centre) and Steve Cardiff (Mount Lorne), after the Party's third member, John Edzerza, resigned to sit as an independent. Edzerza later rejoined the Yukon Party, for which he had originally been elected in the 2002 Yukon election.
Hardy died in July 2010, reducing the NDP to a single seat. On November 12, a by-election was called for his riding of Whitehorse Centre on December 13, which was won by the Party leader Hanson. Cardiff was killed in a car crash on July 7, 2011, again reducing the party to one seat in the legislature entering the 2011 election.
