I'm looking at a person who lived in Scarborough township of Ontario, Canada, in 1871 and 1881. I can find him in the Canada Censuses for both years, but I would like to be able to figure out where he lived. He was a farmer. In the 1871 Census he lives in District 45 (East York), subdistrict C, division 1. In 1881 he lives in District 135 (East York), subdistrict A, division 2. However, I have no idea how to translate those references into actual locations. Can anybody help me with this? I am in the process of developing a 2nd great-granduncle's profile.
