Downsview Airport, formerly IATA: YZD, ICAO: CYZD, was an airport located in Toronto, Ontario, Canada. An air field, then air force base, it has been a testing facility for Bombardier Aerospace from 1994. In 2018, Bombardier sold the facility to Northcrest Developments; in late 2023, Northcrest announced that industrial and airport operations would close by mid-2024, as redevelopment into commercial and residential properties moves forward.[3] The airport was listed as closed March 7, 2024.[1]

Downsview Airport had its own fire service (Bombardier Aerospace Emergency Services) which covered airport operations (using two airport fire rescue vehicles) and plant operations (using two SUV emergency vehicles). Bombardier Emergency Services employees were cross-trained as firefighters, first responders and airport security.


Downsview Airfield[edit]

Downsview Airfield opened in 1929 as general aviation airfield and one of two airports in the area. It was built by de Havilland Canada for testing aircraft at the plant at the site. The site was expanded during World War II by the Royal Canadian Air Force and renamed RCAF Station Downsview.

Downsview Airport[edit]

The Downsview Airport was developed in 1939 as an airfield next to an aircraft manufacturing plant operated by de Havilland Canada. In 1947, the Department of National Defence purchased property surrounding the airfield and expanded it, creating RCAF Station Downsview to provide an air base for Royal Canadian Air Force units. The base was renamed Canadian Forces Base Toronto (Downsview) in 1968 and retained this name until its closure in 1996.

From 1998, the property was administered by a civilian Crown corporation, Parc Downsview Park, which co-managed the airfield with Bombardier Aerospace (the successor to de Havilland Canada).

The airfield was used to host the 1984 and 2002 papal visits by Pope John Paul II, as well as to host the Molson Canadian Rocks for Toronto concert headlined by The Rolling Stones to revive the local economy after the severe acute respiratory syndrome (SARS) outbreak in 2003.

The airfield has also served as a test site for several famous aircraft produced by de Havilland and Avro Canada, including the Beaver, the Twin Otter, and the Dash 8. The airport is available to pilots only with prior permission.

Bombardier Aerospace at one time owned twelve hangars in the southwest corner of the airport, where the Dash 8 was built and assembled. The Bombardier Global Express and the Bombardier Global 5000 were also assembled here at the Downsview plant, as were the wings and wingboxes of the Learjet 45. The Bombardier CSeries jet had landed at the airfield in 2015, but is assembled in Montreal.

The airport had one operational runway, 15/33 at 7,000 ft (2,100 m) with a parallel taxiway. Runway 09/27 at 3,164 ft (964 m) was previously closed (east section removed), as was runway 04/22 at 4,000 ft (1,200 m) (north section removed and south part retained as taxiway into the Bombardier plant).

Bombardier has an agreement to sell the Downsview Airport and its manufacturing plant to PSP Investments. Under the agreement, Bombardier can use Downsview for up to five years. Bombardier signed a lease agreement with the Greater Toronto Airports Authority to build a new facility at Pearson Airport on 38 acres (15 ha) where it would move the production of its Global series planes.[4] Plans for Dash 8 production were not announced at that time. In November 2018, Bombardier sold the Dash 8 business and the DeHavilland name to Viking Air, which has not disclosed its long-term plans for Dash 8 production beyond the existing already agreed-upon timeframe for Downsview.[5]

Farewell of De Havilland Canada[edit]

On June 11, 2022, a private event was held at Downsview Airport, marking the farewell of De Havilland Canada after being located at the airport for 94 years. Many of the past and present employees and their families were invited, and many de Havilland Canada aircraft were being showcased as well as arriving and departing from the airport.

Military housing[edit]

A series of homes were built for Canadian Forces personnel at the corner of Keele Street and Sheppard Avenue West and at the south end of the base property. Access to the north end housing on Robert Woodhead Crescent and John Drury Drive was restricted to base personnel and fenced off from the neighbouring properties. With most of the military base being closed down, the housing has been abandoned and torn down.
