Are you only looking for information about him in British Columbia or about his life in England as well?
I managed to find a few things.
A copy of his death certificate (attached)
A copy of his estate/probate record (attached)
The 1861 Census of England - the last one he was in before he left:
http://search.ancestry.com/cgi-bin/sse.dll?indiv=try&db=...British Columbia was not included in the 1871 Census of Canada.
In the 1881 Census of Canada:
http://search.ancestry.com/cgi-bin/sse.dll?indiv=try&db=...In the 1891 Census of Canada:
http://search.ancestry.com/cgi-bin/sse.dll?indiv=try&db=...Various directory listings:
