A three-tower proposal that would bring 1,043 units to a Mississauga community is slated for the Ontario Land Tribunal.
The proposal to build three apartment buildings with heights of 12, 18 and 22 storeys at the northeast corner of Thomas Street and Joymar Drive in Streetsville is “not acceptable from a planning perspective and should not be approved,” according to a report to the March 9 Planning and Development Committee meeting.
The property is at 64 and 66 Thomas St., 95 Joymar Dr., and 65 Tannery St. and is currently home to a low-rise building containing several auto repair businesses and a small fitness gym.
The developer has taken the application to the Ontario Land Tribunal, which has the authority to override municipal decisions.

The development has been in the works for over a year, and early last year, residents came out to oppose the project. Approximately 120 people attended one community meeting in February 2025. Residents are concerned about increased traffic, parking, shadow, increased crime and a loss of village character in this area of Streetsville.
The plans, from Dezen Realty Company Limited, exceed the maximum three-storey height allowed for this property.
The towers would contain a total of 30 studio units, 681 one-bedroom units, 280 two-bedroom units, and 52 three-bedroom units, according to plans submitted last year. Affordable housing units were not included in the proposal.
City planners are asking for City Council’s support to oppose of the application at the Ontario Land Tribunal, or if possible, to work further with the developer. A date has not yet been set with the Tribunal.
Staff have had discussions with the applicant, but to date, the developer hasn’t submitted a formal revised submission.

While staff agrees the property is underutilized, the proposed height and density represent “a significant departure from the existing and planned vision of the Official Plan and Streetsville Community Node,” the report states.
More information is needed on the traffic impact study and on plans to address the adverse wind effects resulting from the height and placement of the proposed towers, the report states.
The proposed development increases the residential units and overall population while reducing the amount of existing non-residential space.
“The proposed development fails to support the creation of a complete community,”the report states. “To encourage walkability and support the development of a complete community, additional at-grade non-residential floor space would be supported and would benefit future residents.”
