Prospect Cemetery will give you information that everyone has suggested previously, other than who purchased the plot.
If you want to check out where your Charles lived in Toronto you could go to the link below and ask the library to check the Toronto Directories for Charles and include years you wish to have them search. You may want to start with the address on his attestation papers. You are allowed 3 requests at a time, per day. If they don't find anything, please don't get discouraged and keep trying different years.www.torontopubliclibrary.ca
