in 2012. Since 2012 the Veld Music Festival has been held at the park. The Tragically Hip performed to a crowd of approximately 30,000 on Canada Day 2011.

Geography Downsview Park consists of 231.5 hectares (572 acres) of land in the northwest portion of the City of Toronto and the geographic centre of the Greater Toronto Area. These lands were originally home to de Havilland Aircraft of Canada (1929–1947) and then as the RCAF Station/air force base CFB Downsview from 1947 until April 1, 1996, when the base closed. It was also announced that the lands were to be held in perpetuity and in trust as a "unique urban recreational green space for the enjoyment of future generations." The mandate to create the urban recreational green space was given to Parc Downsview Park Inc. (PDP) in 1996 and the title to 231.5 hectares (572 acres) of the Downsview Lands was transferred to PDP in 2006 in order to facilitate the development of Downsview Park. The Department of National Defence (DND) retained 29 hectares (72 acres) of the land to accommodate ongoing military needs. Approximately 150 hectares (370 acres) of the land adjacent to the Downsview Lands (including Toronto's oldest operational airport) is under the jurisdiction of Bombardier Aerospace. A rail line that is used mostly by GO Transit trains runs through the centre of the park. As the mandate for the park requires that it be developed on a self-financing basis, approximately are dedicated to opportunities that provide a revenue stream to finance the construction, development and management of Downsview Park as an integrated, sustainable community. The park features a large man-made pond on the Keele Street side. Although it is an artificial body of water, the water from it flows out to the Downsview Dells ravines and eventually into Black Creek. Public transport access From 1996 to 2017, the closest Toronto subway station to Downsview Park was Downsview station, which served as a terminal station of Line 1 Yonge–University. Situated near the eastern edge of the park across from Downsview Airport, the station was renamed Sheppard West in advance of a northern extension of Line 1, which opened on December 17, 2017. Since
