From Downsview to Pearson: Preserving Bombardier’s Toronto Aviation History

Toronto’s aviation history lives in more than aircraft. It survives in photographs of factory floors, technical drawings, employee publications and the records of businesses that helped shape the city.

Bombardier’s connection to Toronto forms part of a longer story rooted in de Havilland Canada and the Downsview airfield. Exploring that history shows why archives matter: they preserve the details that connect a company’s achievements to its people and community.

The Downsview beginnings

De Havilland Aircraft of Canada began operating at Downsview in April 1929. Its early facility stood beside the railway on land purchased along Sheppard Avenue West. From those beginnings, the site developed into an important centre of Canadian aircraft manufacturing.

During the Second World War, production expanded, employing both men and women and contributing to the local economy. Aircraft associated with Downsview’s history include the Tiger Moth, Mosquito, Beaver, Otter and Dash 8. These aircraft belong to different periods of the site’s history, many predating Bombardier’s involvement.

That distinction matters when describing historical records. A photograph taken at the de Havilland plant in the 1940s should retain its original company name and context, even if the location later became associated with Bombardier.

Bombardier’s Toronto chapter

In 1992, Bombardier acquired Boeing’s de Havilland division, bringing the Dash 8 program into its aerospace business. The acquisition connected Bombardier to an established Toronto manufacturing operation and its regional aircraft heritage.

The corporate story continued to change. In June 2019, Longview Aviation Capital completed its acquisition of the Dash 8 program from Bombardier and launched De Havilland Aircraft of Canada Limited to operate that business.

Bombardier’s own manufacturing presence in the Greater Toronto Area entered another chapter with its move from Downsview to a new Aircraft Assembly Centre at Toronto Pearson. The company scheduled the centre’s official inauguration for May 1, 2024, identifying it as the assembly location for its Global family of business aircraft.

Changes in ownership, aircraft programs and locations make this history especially interesting—and make accurate recordkeeping essential.

Where the history can be explored

Public collections offer several starting points for researching Downsview’s aviation past.

Ingenium’s Canada Aviation and Space Museum archives include an aerial photograph of the de Havilland Canada plant and surrounding area, catalogued as CAVM-11692 and dated approximately to the 1930s. Its description connects the image to Downsview, Toronto, providing a useful reference for understanding the site’s early development.

Toronto Public Library’s Digital Archive Ontario also provides access to photographs from the Toronto Star Photograph Archive. One 1971 image shows aircraft outside the Downsview plant, accompanied by a newspaper caption discussing anticipated layoffs. It offers a reminder that industrial history includes economic uncertainty and workers’ experiences alongside engineering achievements.

These are examples of publicly described historical materials. They should not be mistaken for a complete, publicly accessible Bombardier corporate archive.

Why the description matters as much as the photograph

A factory photograph becomes more useful when its accompanying record identifies the date, location, photographer, aircraft and source. Without that context, a striking image may reveal little about what actually happened.

For a collection spanning de Havilland, Boeing and Bombardier, careful descriptions help distinguish company ownership from aircraft manufacturer, photograph date and present-day custodian. Recording uncertainty is equally valuable: an estimated date should remain an estimate until evidence supports something more precise.

Digitization makes materials easier to view, but meaningful access also depends on consistent filenames, descriptive metadata and a clear arrangement. Researchers need to understand both what an item shows and how it relates to other records.

Preserving the people behind the aircraft

The history of an aviation business includes designers, production workers, administrators, suppliers and families. Employee photographs, newsletters, correspondence and personal recollections can add perspectives that formal corporate milestones leave out.

For anyone caring for a business or family collection, a useful first step is a simple inventory. Identify the materials, preserve existing labels and note who can explain unfamiliar names or events.

Bombardier’s Toronto story illustrates how businesses evolve while their records retain connections to earlier places and people. Preserving those connections helps future generations understand how an industry—and a community—took shape.
