Right now the most promising lead looks like the 1921 census listing for a Donald Robertson who was a inmate at the Colquitz Mental Hospital.
That one isn't very promising. He died 28 Feb 1945 and the information on his death registration is little help in connecting him to the one being looked for.
The informant wasn't a relative and the registration has no birth date listed. The father's name listed matches but not the mother's (first name Mary, maiden surname unknown). It says he was married but only has a given name of Mary for the wife with unknown maiden surname.
It also says he was in Canada for 34 years 8 months of which 34 were in BC. It also says he was living in the jurisdiction where he died for almost 27 years. Not even a close match for someone who emigrated in 1886.
