From the Toronto city website:
The City of Toronto wants to know what you think about expanding permissions for garden suites in the city. Check out the draft permissions 
, draft Official Plan Amendment , and draft zoning by-law amendment . You can also watch a video walking 
through the draft permissions. Send us your comments through our 1-question survey before November 30, 2021.
The Garden + Suites project is one of several studies that the City of Toronto is leading through its Expanding Housing Options in Neighbourhoods initiative . A Garden Suite is a detached housing unit, usually located in the rear yard, and is separate, or detached from the main house. Garden Suites, like Laneway Suites, are generally smaller than the main house on the lot and are intended to function as a rental housing unit.
The Garden + Suites project will review important matters, which include privacy and shadowing, protecting trees and green space, and parking, among many others. This study seeks public input from current and future residents of low-rise neighborhoods, and other stakeholders, to understand these important matters.
The results from this review and public input will inform regulations and recommendations to City Council to permit Garden Suites as-of-right across the city.
For more information about the Garden + Suites project, please see the Garden Suites Review report submitted to the Planning and Housing Committee. Information about other studies currently under review as part of the City’s Expanding Housing Options in Neighbourhoods initiative is also available.
