Is there a way to convert an entry from the 1881 Census of Canada to a street address. I have found members of my family in the 1881 Census in District 105, Sub-Dist A, Div 2, Page 26, Household #125. I cannot find anything more and would like to find a street address in Ottawa for the entries.

Have you consulted an Ottawa city directory? This would give an address and allow you to track the family between each census.
