The Greater Golden Horseshoe is unique globally for its pattern of urbanization due to the proliferation of post-war apartment towers throughout the region.
In 2009 ERA Architects and planningAlliance (the founding partners of CUG+R) as well as the Cities Centre at the University of Toronto, were commissioned by the Ontario Growth Secretariat, in the Ministry of Infrastructure, to analyze this housing resource and examine its future role in our growing region.
The study examined and catalogued the 1,925 Apartment Towers developed in the post war boom (between 1945 and 1984) as well as an additional 1,155 lower rise apartment (5-7 storeys) of the same time period. Together, these post-war apartments contain 496,591 units and make up 17% of all housing in the region, 20% of all housing in the Greater Toronto and Hamilton Area, and nearly a third of all housing in the City of Toronto. The study examines the current condition of this housing resource, and the neighbourhoods they form, throughout the Greater Golden Horseshoe.
The study then explored the potential for reengaging these Towers through a process of neighbourhood renewal to support the realization of provincial priorities including the implementation of the Growth Plan for the Greater Golden Horseshoe, creating a network of regional rapid transit, conserving energy, reducing greenhouse gas production, reducing poverty, providing affordable housing, and building a green economy.
Findings of this research initiative have been published as the report Tower Neighbourhood Renewal in the Greater Golden Horseshoe: An Analysis of High-Rise Apartment Tower Neighbourhoods Developed in the Post-War Boom (1945-1984), was published in late 2010, available here for download.

The primary data source for characterizing and analysing the target building stock was 2006 Municipal Property Assessment Corporation (MPAC) data. MPAC data is used for property assessment purposes by the Ontario government and is the most up-to-date inventory of buildings in the Province. Because the precise characteristics of Apartment Towers, as defined for this study, do not relate to a single MPAC building-type code, a series of MPAC codes were selected that generally captured all buildings over eight storeys that include a residential component. A secondary process of visual confirmation was used to verify the buildings that met the initial criteria, as well as identify towers that were missed due to missing or incorrect data in the MPAC inventory.
Other key data sources for primary research included the 2006 Transportation Tomorrow Survey (e.g, transit use, trip lengths and auto ownership) and the 2006 Census for information related to social need and demographics in Apartment Towers. Additional information related to the housing stock was gained through Canada Mortgage and Housing Corporation housing start data.
Supplementary information included relevant provincial policy documents, as well as local and international case studies related to tower refurbishment.
To investigate linkages with areas of provincial policy interest, the study team conducted a series of interviews in December 2009 and January 2010 and a workshop in June 2010 with staff from the ministries of Transportation, Infrastructure, Energy, Municipal Affairs and Housing, Finance, the Ontario Financing Authority and Metrolinx. Staff from the Ministry of the Environment were also consulted.
