Ajax was incorporated as a Town in 1955, but long before that, several small settlements and farms were found in the area. In 1941, the largest shell filling plant in the British Commonwealth was located in this area to provide supplies for the Allies in World War II. The founding of Defence Industries Limited (D.I.L.) was really the start of Ajax as we know it. As thousands of workers and their families settled in the immediate area, a community developed and a post office was needed, which meant the area needed a name. A competition among D.I.L. employees resulted in the name Ajax being chosen in honour of one of the three ships that, in 1939, had engaged and defeated the German battleship Admiral Graf Spee at the Battle of the River Plate near Uruguay.

After the War, the University of Toronto leased many of the D.I.L. buildings for a new flood of engineering students, and a new population base was added to the area. The community continued to grow and by the early 1950's it was clear that it was time for incorporation as a municipality. Twenty years later, the small community of Pickering Village and parts of Pickering Township were amalgamated with Ajax, forming the Town's current boundaries.

Ajax History Book – Snapshots of Ajax

The Ajax History Book – Snapshots of Ajax is available for purchase for $15 from Ajax Town Hall (65 Harwood Ave. S.).

For a relatively young municipality, the Town of Ajax has an incredibly rich history. Since the Town's incorporation in 1955, Members of Council, Town staff and dedicated residents have worked together to collect and preserve the history of the Town. 

The history of the Town - from its origins through to present days - has been chronicled in a series of books published over the past 40 years. The Town's first history book was published by the Ajax Historical Board in 1972 and provided a pictorial account of the establishment and early years of a new municipality. The second book, titled "A Town Called Ajax" and also published by the Ajax Historical Board, looked at the growth of the Town to 1995.

Carrying on this tradition, a dedicated team of Town staff and an amazing group of community champions recently took on the enormous task of researching, writing, editing and publishing: "Snapshots of Ajax - A Pictorial History, 1791 - 2015", a collection of 700 timeless and historically significant photographs, this book captures the origins, growth and diversity of the Town from its earliest settlement into the 21st century.

Town of Ajax Archives

In February 2010, Ajax Council formally established the Ajax Archives, to collect and preserve archival materials which illustrate or document the growth and development of the Town of Ajax. The history of the community that has become the Town of Ajax is as unique as it is diverse. The photos, artifacts and records which document the inception, growth and development of the municipality are a legacy to future generations. The preservation and conservation of the items in the Ajax Archives is an important step to ensuring this history is kept safe, and is accessible to the community.

The Ajax Archives is located at Town Hall, 65 Harwood Ave., S., and access is by appointment only. The display case in Town Hall is changed on an annual basis, providing the public with an opportunity to see the photos and artifacts relevant to the community history.

The Ajax Archives collaborated with the Ajax Public Library to digitize many of the photos, documents and history books in the collection. These are available through using the search bar and quick searches below, or by visiting the OurOntario website.

Additional History and Archive Resources

Ajax has a unique street naming policy, in that the majority of streets have been named after those that served on HMS Ajax, HMS Exeter and HMS Achilles during the Battle of the River Plate, the first naval victory of the Allied forces in WWII. Several streets have also been named after individuals who played an important role in the creation of our community.
