I guess the question is, what research have you done to date, including - have you engaged the services of a genealogist in the Ottawa area to access his personnel file yet (or have you made the trip yourself)? Library and Archives Canada maintains these records. Have they been able to assist you?
It's nice to see this history preserved. Hopefully a photo of the officer will surface.
His attestation paper should be online, unless you've already accessed that as well - the CEF's attestation papers were all recently digitized - let us know if you need help accessing these.
