On January 12, 2022, Planning and Housing Committee will consider item PH30.2 which includes the proposed draft Official Plan Amendment and draft Zoning By-law Amendment to permit the development of Garden Suites in residential Neighbourhoods across the City of Toronto (Final Report, Agenda and Notice of Public Meeting).


Expanding Housing Options in Neighbourhoods is a City of Toronto initiative to facilitate more low-rise housing in residential neighbourhoods to meet the needs of our growing city. The City is working to expand opportunities for “missing middle” housing forms in Toronto, ranging from duplexes to low-rise walk-up apartments. All of these housing types can be found in many parts of Toronto today, but they are also limited in where they can be newly built. Expanding Housing Options in Neighbourhoods is one solution among a range of City initiatives to increase housing choice and access and create a more equitable, sustainable city.

Priority projects endorsed by Council to be advanced in 2020-2021:

  • permitting new types of accessory housing such as garden suites and coach houses
  • allowing more residential units in forms compatible with existing houses, such as duplexes and triplexes, where they are currently not permitted
  • zoning to allow more low-rise housing options on major streets
  • Beaches East York Pilot Project

More information and opportunities for input will be posted as these projects and other parts of the work program move forward.

The Official Plan and Zoning By-law work together to implement the City’s vision for future land use and development:

  • Official Plan land use designations establish the City’s general growth management policies, describing where housing can be built, where stores, offices and industry can locate and where a mix of uses is desired.
  • The Zoning By-law is the legal tool that implements policies of the Official Plan, establishing regulations for how land can be used, what types of buildings and structures can be built, as well as standards related to the location of buildings and structures, lot sizes and dimensions, parking requirements, building heights, and setbacks from property lines.

The following graphics show how much of the City of Toronto’s total area is in each Official Plan land use designation and Zoning By-law zone category. One square represents one percent of the City of Toronto’s area.

Although zoning by-laws must generally conform to the Official Plan, the exact breakdown of land areas in land use designations and zone categories varies due to differences in how these areas are drawn and measured. For example, Official Plan land use designations do not include rights-of-way, whereas zones are based on property boundaries extended to the centreline of adjacent streets.

Residential Zones

The graphic below illustrates the percentage of the City of Toronto’s total area subject to Residential zoning (47.1%). On its own, the Residential Detached (RD) zone makes up 31.3% of the city’s total area. 15.8% of the city’s total area consists of Residential zones (R, RS, RT and RM zones), most of which permit a variety of Missing Middle housing forms. Secondary suites are permitted in all Residential zones.

City of Toronto - zoning by-law residential zoning. 47.1% of toronto's total area is zoned residential. 31.3% of toronto's total area is zoned to permit detached houses. 15.8% of toronto's total area is zoned to permit other low rise residential buildings.

  • Official Plan Land Use designation areas do not include rights-of-way (e.g. roadways). To account for lands not subject to a land use designation, the blank squares in Image 1 correspond to the difference in the total land area of the City of Toronto less the sum of all Official Plan designated land use areas.
  • Zone category areas are measured using parcel dimensions, including adjacent rights-of-way. Certain zoning boundaries extend into bodies of water, therefore the total zoned area (644.47 km2) is greater than the City of Toronto’s total land area (634.04 km2). Some areas of Toronto are still subject to the legacy zoning of the former pre-amalgamation municipalities. These areas were assigned to the closest matching zoning category in Zoning By-law 569-2013 for the purpose of these graphics.
  • Site or area-specific zoning may permit or restrict specific uses or modify standards.
