Hi again Peter,
I haven't gotten obits for the John R. and Grace E. McIntosh's you found but I did find them in the 1916 census living in Edmonton West. They were both born abt 1878 and had three children.
I also found in the 1916 census the John R. McIntosh I am looking for still living in Saskatchewan in the Smiley, Kindersley area. The census shows that he was b. abt 1887 and was a single man working with farm machinery, which fits the profile.
So, unfortunately, the search goes on.
Thank you for your interest and the information. I had my fingers crossed.
Dan
