William John Lang was born 27 October 1881 in Hamilton, Ontario. His parents were Thomas Henry Lang (a brakeman on the railroad) and Louisa Lewis.

The 1911 Canadian Census shows William working as a cook for the railway and living in Fort William, Ontario.
William enlisted for WW1 in Kenora on 25 May 1915. His occupation at the time was fireman for the CPR and he was single.

Upon his arrival in England he was taken on strength by the Canadian Railway Transport Depot. On 20 September 1918 William went to France with the 3rd Battalion of the CRT and joined his unit in the field on 03 October. He served in France until 05 January 1919 when he was returned to England. In February he returned to Canada aboard the Carmania and received his official discharge due to demobilization on 01 March 1919 in London, Ontario. His proposed residence on discharge was London, Ontario.
