Q & A - Garden Suites

On January 25, 2022, the Long Branch Neighbourhood Association hosted the Allendale Residents Association from Barrie Ontario to present their experience with Garden Suites. A number of questions and comments were raised at the meeting. City Planning staff were in attendance but were not part of the panel of presenters. In order to respond to the questions and comments from the discussion, City Planning have provided the following Q&A that reflect the themes from discussion at the meeting.

1) How are trees protected on the property where a Garden Suite is proposed, as well as trees on Neighbouring properties? Can the City prohibit development on lots where trees will be impacted?

The City of Toronto has a tree protection By-law, which applies to all trees on private property with a diameter of 30cm at breast height. In contrast, the City of Barrie has a By-law to protect woodlots and does not protect individual trees on a property.


In practice, in cases where a Garden Suite is designed to meet the proposed By-law rules (i.e. as-of-right construction), but construction would necessitate the injury or removal of a tree, the General Manager of Parks, Forestry, and Recreation may refuse the tree permit, in accordance with Municipal Code Chapters 608, 658, and 813. The applicant may appeal the decision to the appropriate Community Council. This practice is unique to laneway suites and garden suites, representing an elevated level of oversight and protection of neighbourhood trees, when compared to any other type of low-rise construction in Neighbourhoods.


The proposed Garden Suites by-law also includes requirements for green space on a lot. It requires that a minimum of 50% of the total rear yard area must be soft landscaping (such as trees, grass, and gardens). For lots with a frontage of less than 6.0 metres, a minimum of 25% of the rear yard must be soft landscaping. These requirements are the same as the existing zoning by-law standards for soft landscaping in the rear yard of residential properties. In addition to providing amenity space that may serve the residents of a lot, soft landscaping in rear yards presents an important opportunity to provide the permeable space needed to retain storm water on site, and support tree and ecological functions.


City Planning Staff worked closely with the City’s Urban Forestry staff in the development of the Garden Suites standards.
