When getting started with census records in Ontario, a good background knowledge of Ontario History and historical Ontario Maps can assit you with finding the location of your ancestors. Once a location has been found you can utilize Microfilms to locate census records or contact local Genealogical Societies. Topic related Mailing Lists & Newsgroups can also be very useful.
