The Toronto Branch of the OGS has produced an indexed transcription of the Toronto tax assessment rolls for 1853. The original assessment rolls for 1853 are at the City of Toronto Archives.
There are two parts of the assessment rolls -
The first part of the project is a searchable online index available on this web site www.ontarioroots.com/ogs
The index (more than 9,000 names of owners and occupiers) and images is available free of charge to researchers around the world.
The second part of the project is a book and CD version of the index with lots more information for researchers with interests in mid-19th century Toronto.
There are maps and descriptions of the wards and streets, vital records, religious records and cemeteries, land records, immigration, directories, published sources and historical background.
