I have an Elmer Doner married to Isabell Thomas.Isabell was born Aug 12, 1907 and died Mar 02, 1979.Elmer and Isabell had the following children; Eleanor b. 1929, Harold b. 1930, Elmer b. Sep 17, 1932, Rosalie b. 1939, Gertrude b. ? and Isabell b, ?.Not sure if this is the same Elmer you are looking for but I can find nothing on this family in Canada.It is entirely possible that they moved to the United States since so many others from the Thomas/Gaston family did.
