Canadian Forces Base Toronto is a former Canadian Forces base in Toronto, Ontario. The airfield is currently operated as Toronto / Downsview Airport.

Downsview Park (French: Parc Downsview) is a large urban park located in the Downsview neighbourhood of Toronto, Ontario, Canada. The park's name is officially bilingual due to it being federally owned and managed, and was first home to de Havilland Canada, an aircraft manufacturer, and later was a Canadian Forces base. The park still contains Downsview Airport. In 1999, the Government of Canada declared it as "Canada's first urban national park". However, unlike the Rouge National Urban Park in eastern Toronto, Downsview Park is managed by the federal Crown corporation Canada Lands Company rather than Parks Canada.
