In Mississauga, Infrastructure Ontario is looking to transform Clarkson GO station's north commuter parking lot into a seven-tower Transit-Oriented Community (TOC) rising from 25 to 45 storeys. The plan would introduce more than 2,400 homes across three blocks that wrap around Sheridan Creek, which bisects the site west of Southdown Road.
The Province’s Transit-Oriented Communities program directs housing and mixed-use growth to lands immediately surrounding major transit investments. Infrastructure Ontario is advancing this plan under the Clarkson GO Major Transit Station Area (MTSA). This is a pre-application submission, with the Planning Justification Report prepared by Fotenn Planning + Design noting that the forthcoming MTSA policy framework is anticipated to reflect the TOC proposal, but a Zoning By-law Amendment would still be required.
The 3.86-hectare site at 2130 Bromsgrove Road occupies the southwest corner of Bromsgrove and Southdown roads, directly to the north of Clarkson GO station on the Lakeshore West line. Today, it functions almost entirely as commuter infrastructure, containing station entrances and a 1,020-space surface parking lot. The proposal would replace this with underground parking.
Designed by Zeidler Architecture, the plans call for three development blocks framing a new internal street. Across Blocks A, B, and C, seven towers from 25 to 45 storeys would rise above six-storey podiums, with heights ranging from 87.75m to 147.75m. Together they would deliver 191,181m² of residential Gross Floor Area and 2,161m² of retail area, supported by expanded POPS (Privately-Owned Publicly-accessible Spaces) and new connections to the GO station. In total, the community calls for 2,434 residential units.
Block A, positioned farther from the station entrances and planned to be built first, would include three towers of 25, 30, and 40 storeys containing 930 units, arranged around an L-shaped podium fronting Bromsgrove. Block B, on the southwest side of the creek, would add a single 45-storey tower with 430 units above a stepped podium. Block C would anchor the station entrance with three towers of 35, 40, and 45 storeys joined by a T-shaped podium, contributing 1,074 units and the largest share of retail space.
Indoor amenities would total 7,321m², with outdoor terraces and landscaped areas contributing another 5,936m². Vertical circulation would be handled by three elevators per tower. This translates to roughly one elevator per 103 units in Block A, one per 143 units in Block B, and one per 119 units in Block C, indicating motors of varyingly high speeds would be required for adequate response times.
Below grade, each block would contain its own garage, combining to provide 513 resident parking spaces, 58 visitor spaces, and 1,020 spaces allocated for GO commuters. Cycling facilities entail 1,751 long-term and 350 short-term bicycle spaces.
The public realm would be organized as a continuous network of streets, green edges, and plazas. A total of 6,570m² of POPS is planned among the three blocks. Tower spacing would generally follow the City’s Tall Building Guidelines, with most separations reaching 25 to 30m, though the pairing of Towers C2 and C3 would tighten to 20m at the corners.
Located at a GO Transit station, the site is served by Lakeshore GO Trains, MiWay, Oakville Transit, and GO bus routes operating along Southdown Road. (Block C is planned with the flexibility to accommodate a future 14-bay bus loop with five layover spaces near the station entrance.) Tor cyclists, protected lanes are proposed for the new internal road, with direct access to the Nine Creeks Trail.
There is other development activity in the surroundings. Stonebrook Condominiums, an 18-storey tower southeast of the station, reached completion earlier this year, marking one of the first high-rise addition to the area in about a decade. Farther east along Royal Windsor Drive, a proposal at 2077 Royal Windsor outlines four towers ranging from 25 to 35 storeys.
As the proposal advances, Infrastructure Ontario is moving into its next phase of public consultation, with both virtual and in-person engagement sessions scheduled for January 22 and 29, 2026.
