Introduction`

"Dull, inert cities, it is true, do contain the seeds of their own destruction and little else. But lively, diverse, intense cities contain the seeds of their own regeneration, with energy enough to carry over for problems and needs outside themselves."

- Jane Jacobs

As a former military base, Downsview’s transformation offers a unique opportunity to address urban density, sustainability, and public space, yet it also raises questions if a development this large is able to achieve goals outlined in the id8 framework. Would the framework benefit on "bigness" — grand, singular gestures of infrastructure and monumental design — or with more community-oriented, step-by-step incremental growth? The tension between large, impactful projects and the need for organic, incremental densification may result in overlooking the day-to-day experiences of the residents and users who engage with the space. 


Goals of our framework analysis



  1. Investigate incremental development on site
  2. Explore the idea of “bigness” with preserving heritage buildings
  3. Analyze block densities for different neighbourhoods/regions

1793







               
The Downsview community was settled after the founding of York in 1793.

In 1827, William Duncan came from Ireland to Downsview and built a homestead and farm on the land that is now 40 Carl Hall Road. Edward Boake and his wife, Sarah, owned a large parcel of land on which they built their house, “Locust Lodge,” named for the surrounding locust trees.

In 1843, John and Caroline Bull settled on 81 hectares of land in York Township and called their home “Downs View.” The name was later adopted by the community as “Downsview"



1929

         
In the late 1920's land in the Downsview area was used for airfields—Barker Field, the Canadian Express Airport and the Toronto Flying Club.

De Havilland Canada moves to Downsview, with their first hangar was built in to produce the Gypsy Moth aircraft. In April 1929, the company purchased 28 hectares (70 acres) of Downsview farmland next to the railroad tracks. De Havilland outgrew the tiny hangar, and so the company began construction on what was then called Plant Complex One.




1929-1938

In April 1929, the De Havilland Aircraft of Canada purchased 28 hectares of farmland along Sheppard Avenue West, where they built their own airfield for commercial operations. They began a 1,858 square metre plant next to the railway (now 65 Carl Hall Road).

Between 1936 and 1938, De Havilland added a paint shop, hangar and a main building south of the original plant (now 75 Carl Hall Road). De Havilland’s staff grew to some 2,400 employees.





1952

                    In response to the onsite military expansion, De Havilland moved its operations southeast to newly constructed modern facilities, on the southwest corner. The RCAF built barracks, headquarters and maintenance buildings on the property between 1952 and 1956.

In 1952, the Department of National Defence acquired Downsview land and buildings owned by de Havilland. De Havilland was granted a long-term lease on the 36 acres south of the airfield east of the railway where they built new facilities, but also continued to use some of their former manufacturing buildings to the north.



1953

          Enlisted soldiers and their families lived in Stanley Greene Park, while the families of commissioned officers lived in William Baker Park

Charged with the task of protecting the airspace of Toronto in the event of a war, officers, soldiers, and members of the reserves and militia focused their day to day efforts on logistics and supplies for military missions abroad, training drills, testing survival gear, supporting local armouries, and being available for local emergencies.




Military-Use
Decomissioned Base In 1995, the federal government decommissioned the Canadian Forces Base Toronto and announced that the land would be set aside for development, recreational and broader public uses. The base formally closed on April 1, 1996. Parc Downsview Park Inc. (PDP) was established in 1999 to build and operate Downsview Park.

Headlined by Rolling Stones, an estimated 450,000 and 500,000 people attended the concert, making it is the largest outdoor ticketed event in Canadian history and one of the largest events in North American History







2006

                                In 2000, the jury unanimously selected OMA/Rem Koolhaus and Bruce Mau Studios for their submission “Tree City". Their proposal offered a formula to develop programmed and unprogrammed space over time that would be informed by the site’s ecological and environmental conditions while flexible enough to respond to the community’s changing needs. Based on this plan, Downsview Park was established as a 81 hectare (200-acre) centrally located urban green space

Instead of creating a park made up of almost entirely green space as called for in the "Tree City" plan, Parc Downsview Park Inc., the crown corporation then in control of the park, approved constructing commercial and residential developments across the north, east and southwest ends of the park (developed by UrbanCorp and Mattamy Homes)

Construction began in 2006 and completed in 2012.
