Gideon Decker Robertson, PC was a Canadian Senator and Canadian Cabinet minister. Robertson was a telegrapher by profession and had links with conservatives in the labour movement. In January 1917, he was appointed to the Senate as a Conservative as a means of bringing in labour representation during the First World War. When Prime Minister Sir Robert Borden formed a Unionist government in October as a means of creating a national government for the war effort, he made Robertson minister without portfolio in order to give Cabinet representation from labour. On November 8, 1918, Robertson became Minister of Labour.
