Researching the History of Your House in Toronto
Researching the history of your Toronto house, or any other building in the city for that matter, can be a rewarding, though sometimes frustrating activity. Fortunately many resources are available online, so that some of your research can be done at any place and any time. My favourite is in bed in my pyjamas early in the morning.
Step 1: Use Personal Observations, Interviews and Documents
1.1. Look at your house and its setting in the neighbourhood.
The age of your house may be indicated by its architectural style and whether it looks the same or different from other buildings on the street. A careful examination of your house also will show if alterations or additions have been made over the years.
1.2 Talk to previous owners, neighbours and long-time residents.
You may discover the approximate age of your house; construction details, such as additions and renovations; the names of previous owners and occupants; and photographs of your house, its occupants, and the neighbourhood
1.3 Look at your deed, assessment notice, or tax bill.
These documents may tell you the legal description of your property (lot, concession, and subdivision plan numbers) and the name of the municipality in which the property is located. The information will be useful (and sometimes necessary) for further investigations, especially using tax assessment rolls and conducting land title searches.

Step 2: Use Primary Resources Available Online and at Libraries and Archives
You are now ready to consult the "big three" – fire insurance plans, city directories and assessment rolls – but start with the first two, which are easy to use and many years are online.
2.1. Fire insurance plans
Fire insurance plans, sometimes called Goad’s atlases, are a quick way to narrow down when a building was constructed.
Streets and buildings are shown in great detail on these maps. Published from 1858 to 1973, they can be used to discover details about your house including size, shape and construction materials.
Fire insurance atlases and plans published after 1924 are within copyright and are only available at libraries and archives
Helpful guides to fire insurance plans

- Digital Toronto Fire Insurance Atlases and Plans. Chronologically arranged links to Toronto fire insurance atlases and plans, 1858-1924, available digitally from Toronto Public Library, Nathan Ng’s Recursion, City of Toronto Archives, University of Toronto, Library and Archives Canada, and other sources.
City directories are a convenient way to estimate the date of construction for a property. The directories may show when a site was developed and the names of occupants over the years. Published from 1833 to 2001, the directories usually are organized alphabetically by both street name and occupant's surname.
Begin by locating your street name in the alphabetical list of streets. Check the street number every five or ten years to develop a history of the building's use and occupants, and to narrow the time when the house began to appear in the directories. Once you have established a date range, check the street number, year by year, to pinpoint precisely its first appearance. By finding the first date that a building appears in the city directories, you can estimate a probable date of construction. By working forward, you can complete a list or property owners and/or occupants.
Be aware that the information in any volume was usually compiled the previous year (for example, the directory for 1900 reflects the status of the site in 1899). Also, a directory lists the occupant of the property who may or may not be the owner.
Also be aware of infill. Sometimes a directory will indicate that a building, which is now located in mid-block, as being at the corner if no closer buildings to the corner have been built by that time. Maps should be consulted to avoid confusion.
Many Toronto neighbourhoods were once small villages or independent municipalities, which may be listed in a separate section in city directories

2.3 Assessment rolls
For more accurate information about buildings, city assessment rolls must be consulted. Prepared annually by local municipalities as part of property tax calculations, assessment rolls show the name, occupation, salary, and religion of the “head of household”, as well as the size, buildings, ownership, and assessed value of the property. This detailed data should verify and amplify information found in city directories. Assessment rolls also may indicate changes to a property. An increase in assessed value from one year to the next could suggest the construction of a building or an addition.
The City of Toronto Archives holds the major collections of assessment rolls, in hard copy and on microfilm, for Toronto and its predecessor municipalities. You will need to visit the Archives to see them. (Toronto Public Library also has a small collection of Toronto assessment rolls.)
Assessment rolls are organized by municipality. Therefore, you will need to identify the municipality where a property was located when the assessment was made. For example, between 1834 and 1909 sections of today's Beach neighbourhood were part of the City of Toronto, York Township and East Toronto; after 1909 they were all were within the city. If your property used to be in the old City of Toronto, find names of predecessor municipalities using Toronto annexation maps 1915 and 1967.
The following map shows the municipalities and their incorporation dates that became part of Metropolitan Toronto in 1953.
Post-1998 assessment rolls are also organized by the six pre-1998 municipalities, even though they are all now part of the City of Toronto. For current assessment information about your property, you can use the Toronto Property System database, available at the City of Toronto Archives and civic centres.
Be aware of changes in street names and numbers. Some streets in Toronto have been renamed or renumbered over the years. For information on street name changes, consult:
- Fire insurance plans for Toronto.
- Street section in the city directories.
- Online Street name changes in Toronto for 1901 data.
- A "Street name list" prepared by the City of Toronto's Geospatial Competency Centre. Electronic copies are available at the Reference Desk, Humanities and Social Sciences Department, 2nd floor, Toronto Reference Library and the City of Toronto Archives. The list includes almost 10,000 Toronto streets. Information is provided, when applicable or available, on existing and former street names, subdivision plans, names origins and other valuable details.
To avoid confusion on street number changes:
- Compare directory listings with maps. Toronto fire insurance plans are especially useful for locating specific buildings and for providing the street number of buildings, which usually are indicated on the street in front of the building.
- Always keep a record of the occupant's name for each year, as well as the names of the occupants on either side. If all three names or numbers change, then the street has been renumbered. Search the street until you find the same sequence again.
- If the first year your property appears is not described as "unfinished house" or "vacant," you may have simply have encountered a re-numbering of the street.
