About Downsview Airport
Downsview Airport, formerly IATA: YZD, ICAO: CYZD, is a defunct airport located in Toronto, Ontario, Canada. An air field, then air force base, it had been a testing facility for Bombardier Aerospace from 1994. In 2018, Bombardier sold the facility to Northcrest Developments, a wholly owned subsidiary of the Public Sector Pension Investment Board; in late 2023, Northcrest announced that industrial and airport operations would close by mid-2024, as redevelopment into commercial and residential properties moves forward. The airport was closed as of April 2024. On 17 August 2024, Northcrest Developments unveiled a new identity for the 1.5 km2 of the former Downsview Airport lands drawing on the site’s history: YZD, as the transformation kicks off.
