A new proposal has been submitted to the City of Mississauga for a site dubbed Forest Park Circle in the Rockwood Village neighbourhood, transforming what was once planned as a two-tower condominium infill development into a six-tower residential community. Designed by 4 Architecture Inc for Lormel Homes, the new plans would add three new 20-storey towers alongside a previously approved 25-storey building while retaining the site’s two existing 18-storey rental apartment towers. The proposal marks a significant evolution from the former Chelsea on the Green concept, increasing the maximum height from 15 to 25 storeys—the tallest in the area—and shifting from a condominium-focused project toward a mix of rental and flexible residential tenure options.
The proposal applies to the 3.75-hectare property at 4100 Ponytrail Drive and 1850 Rathburn Road East. The site is occupied by two 18-storey rental apartment towers built on a Tower-in-the-Park style setting of landscaped open space and surface parking. Across Rathburn to the north is a commercial plaza anchored by Longo’s and Shoppers Drug Mart, with townhouse and detached housing and extensive parks in the surrounding lands.
An Official Plan Amendment application was first submitted in 2012 for what was then known as Chelsea on the Green, a Turner Fleischer-designed condominium project proposing two infill towers of 12 and 15 storeys alongside the existing rental buildings. The proposal received approvals following several years of review and public debate, but never advanced to construction. More recently, a Minor Variance approved in May, 2025 permitted one of the planned buildings to rise to 25 storeys. That tower is now proceeding through Site Plan Approval, while the latest submission adds three more residential buildings. Glen Schnarr & Associates Inc has submitted Official Plan and Zoning By-law Amendment applications to the City of Mississauga on behalf of the developer.
The revised proposal would introduce three new 20-storey apartment towers rising to 70.25m, joining the approved 25-storey, 81m-tall tower. Located in the southern portion of the property adjacent to a hydro corridor and open space lands, the new buildings would expand the previously approved infill concept into a six-building community.
The latest plans would add 695 units, comprising 233 one-bedroom units, 154 one-bedroom-plus-den units, 202 two-bedroom units, 51 two-bedroom-plus-den units, 19 three-bedroom units, and 36 three-bedroom-plus-den units. Combined with the approved 285-unit tower, the proposal would increase the number of new units from 278 under the previous plan to 980, over and above the 385 units in the two existing buildings. The residential Gross Floor Area would rise from 24,295m² to 70,579m², while Floor Space Index would increase from 1.60 to 2.75 times coverage of the property. The application would permit a range of tenure options, including rental housing, senior-oriented housing, and commercial uses.
The new towers are proposed atop five-storey podiums, with floorplates ranging from approximately 588m² to 750m². Separation distances would include 30m between the proposed towers, 24m between one new building and an existing rental tower, and 46m between another new building and the second existing tower. The approved 25-storey tower is planned to sit 27m and 31m from the existing buildings. Indoor and outdoor amenity space is proposed at approximately 3.5m² per unit. Each new tower would be served by three elevators, translating to roughly one elevator for every 73 to 95 units, depending on the building, indicating generally satisfactory response times.
Parking would be accommodated through a two-level underground garage connecting the existing parking structure with the approved and proposed phases. The development would provide 771 vehicular parking spaces, including 670 resident and 101 visitor spaces, compared to 429 spaces in the earlier scheme, which included 373 resident and 56 visitor spaces. Bicycle parking would total 452 spaces.
The site is served by MiWay Route 20, with stops directly in front of the property providing connections to Kipling Station on Bloor Line 2 in Toronto. Route 26 Burnhamthorpe is accessible nearby along Burnhamthorpe Road East. Regional transit access is available through the Dixie Transitway Station, approximately 20 minutes away by transit, where GO Bus routes provide connections across the GTHA. Multi-use trails run along Rathburn Road East and Ponytrail Drive, with direct access to the adjacent Hydro One corridor trail system and cycling infrastructure along Burnhamthorpe Road East.
The proposal joins a growing number of higher-density residential projects emerging around the Mississauga–Etobicoke border. To the east in Etobicoke, the 20-storey 340 Mill Road is under construction, 210 Markland would introduce three towers ranging from 9 to 12 storeys, and 4340 Bloor West is planned at 13 storeys. South of the site in Mississauga, redevelopment proposals include the 14-storey 1785 Bloor Street, the 17-storey 1750 Bloor Street, a pair of 18-storey towers at 1840-1850 Bloor Street, and the three-building 3403-3445 Fieldgate Drive proposal ranging from 13 to 22 storeys. 1315 Bough Beeches is proposed southwest of the site at 13 storeys.
