An abandoned airport in Toronto, Canada, is on the brink of a remarkable transformation into a £22 billion city designed for approximately 50,000 residents. Downsview Airport ceased operations in 2024, paving the way for a massive redevelopment project estimated at $30 billion, equivalent to roughly £22 billion, to create a new urban hub named YZD.
The ambitious YZD project is set to unfold over a span of more than 30 years, encompassing a variety of amenities such as homes, shops, schools, and parks. This initiative is hailed as one of the most ambitious undertakings in North American history.
A key feature of the redevelopment plan involves converting the former 1.24-mile runway into a central park that will serve as the “connective tissue” linking different neighborhoods within the area. Recent revisions for the Downsview West District segment of the airport site have refined proposals for a mixed-use community centered around Downsview Park TTC and GO station.
According to Urban Toronto, the updated plans for Downsview West District were submitted by firms including Urban Strategies, Trophic Design, and ERA Architects, aiming to enhance the district framework based on valuable feedback received. YZD is highlighted as one of the largest urban transformation zones in North America, with Downsview West emerging as the first key district managed by Canada Lands north of Downsview Park.
The development plans are structured around three main areas: Station Quarter, Heart at the Crossroads, and the Mews neighborhood, with taller structures strategically positioned in close proximity to transit facilities. These towers are projected to reach a maximum height of 197 meters. As part of the submission, considerations are made for tower placements, the transition between buildings of varying heights, and the selection of construction materials.
Originally used for warplane production during World War II, Downsview Airport later transitioned to an aerospace facility in the 1990s. Derek Goring, CEO of Northcrest Developments overseeing the project, emphasized the importance of preserving existing structures to bring character and uniqueness to the redeveloped area. The proposed development aims to deliver approximately 8,800 residential units, with 20% designated as affordable housing, alongside a blend of employment, retail, institutional, and community facilities.
Furthermore, the plans introduce the Depot Mews concept, promoting a “shared street” approach to enhance community interaction. Derek emphasized the environmental benefits of retaining existing buildings to reduce carbon emissions, emphasizing sustainability in the project’s design and execution.
