East York Records


East York has left its mark on the rest of Toronto through the red bricks supplied by the Don Valley Brick Works. In more recent times, the oases of its riverside parklands have been enjoyed by people from all over the city.

The City of Toronto Archives has records, created by municipal governments as well as private groups and individuals, about East York, including personal papers; published books and reports; and visual material, including maps and photographs.

Toronto City Directory 1926

City directories

Some areas of East York are listed in the Toronto city directories in a separate suburban section (see each year's table of contents for page numbers) from 1890 to 1929. Starting in 1930, East York listings are part of the main directory.

Between 1983 and 1995, East York listings appear only in the "central" and "east" editions of the directory, which are not published every year. After 1995, East York listings appear in one volume entitled "City of Toronto (east of Yonge) and East York."

Directories are available on microfilm, found in the self-serve cabinets in the Microfilm Room.

The Archives also has a copy of a Directory and Map of the Township of York (917.13540025 ON8 1909) for 1909, which includes listings for East York villages. Ask Reference Desk staff to retrieve this directory for you from closed reference.

Fire insurance plans

A small part of western East York appears on fire insurance maps starting in 1890. A larger area appears in the 1910 revised volumes. These maps are available online.

Larger areas can be found in the volumes for 1944, 1950, and 1956. They are found in boxes titled "Goad's" or "Underwriters'" in the metal cabinets in the Microfilm Room.

Each set of maps begins with a key map and an index of street names. You can use either to find your area. 


To find maps showing East York, use the Gencat database. Reference Desk staff can show you how to use the database. The Archives also has several atlases that may be useful. They are found at the back of the Research Hall.

Aerial photos

The aerial photographs cover the East York area from 1947 to 1992. A selection of years is online. A smaller group of valley lands from 1937 to 1942 is also online. A more complete run of years is available on computers in the Research Hall.


The Archives holds published reports regarding East York, including those on topics such as public transit and roads. To find them, search the Gencat database on your topic.
