He was born and raised in Peace River, Alberta, and moved to Teslin, Yukon in 1949.
[1] In Teslin he worked as the owner of a construction company and a wilderness lodge,[1] and competed in various sports including curling[2] and dog mushing.
[3] Following the replacement of the Territorial Council with the Legislative Assembly of Yukon and the resultant introduction of political parties in the territory, Teslin was redistricted into the new riding of Campbell,[4] and Fleming was reelected as MLA for Campbell in the 1978 Yukon general election; however, he did not join a political party as he was opposed to the introduction of party politics to the territory at that time,[5] and instead ran and was elected as an independent MLA.
[6] He joined the Yukon Progressive Conservative Party in 1981,[6] although he declined an offer to be appointed to a cabinet post in the Executive Council of Yukon because he felt that other MLAs were more qualified to hold cabinet roles than he was.
[8] Following his retirement from politics he moved to Chilliwack, British Columbia, where he died of a heart attack on February 15, 1985.
