TOC proposed with seven towers next to Clarkson GO in Mississauga
In Mississauga, Infrastructure Ontario wants to convert the Clarkson GO station's northern commuter parking lot into a seven-tower Transit-Oriented Community (TOC), expanding from 25 to 45 stories. The plan calls for the creation of more than 2,400 homes in three blocks centered around Sheridan Creek, which bisects the site west of Southdown Road.

The province's Transit-Oriented Communities program directs housing and mixed-use development to areas immediately adjacent to key transit investments. Infrastructure Ontario is advancing this plan as part of the Clarkson GO Major Transit Station Area (MTSA). This is a preliminary submission of the application. The planning justification report prepared by Fotenn Planning + Design notes that the upcoming MTSA policy framework is expected to reflect the TOC proposal, but an amendment to the zoning bylaw would still be required.

The 3.86-acre site at 2130 Bromsgrove Road is located on the southwest corner of Bromsgrove and Southdown streets, just north of the Clarkson GO station on the Lakeshore West line. Today it serves almost exclusively as commuter infrastructure and has station entrances and a surface parking lot with 1,020 spaces. The proposal would replace this with an underground car park.

The plans, designed by Zeidler Architecture, envisage three development blocks framing a new internal road. In Blocks A, B and C, seven towers of 25 to 45 storeys would rise above six-storey podiums, with heights ranging from 87.75 m to 147.75 m. Together they would create 191,181 m² of residential gross floor area and 2,161 m² of retail space, supported by expanded POPS (Privately-Owned Publicly-Accessible Spaces) and new connections to the GO station. In total, the municipality is demanding 2,434 residential units.

Block A, which is further from the station entrances and would be the first to be built, would comprise three towers of 25, 30 and 40 storeys with 930 units arranged around an L-shaped podium fronting Bromsgrove. Block B, on the southwest side of the creek, would add a single 45-story tower with 430 units above a stepped podium. Block C would anchor the station entrance with three towers of 35, 40 and 45 floors connected by a T-shaped podium and would contribute 1,074 units and the majority of retail space.
Interior amenities would total 7,321 m², while outdoor terraces and green spaces would account for a further 5,936 m². Vertical circulation would occur via three elevators per tower. This equates to approximately one elevator per 103 units in Block A, one per 143 units in Block B, and one per 119 units in Block C, suggesting that adequate response times would require motors at different high speeds.

Below grade, each block would contain its own garage, which would collectively provide 513 resident parking spaces, 58 visitor spaces and 1,020 GO commuter spaces. The bicycle traffic facilities consist of 1,751 long-term and 350 short-term bicycle parking spaces.
Public space would be organized as a continuous network of streets, green spaces and squares. A total of 6,570 m² of POPS is planned in the three blocks. The spacing between towers would generally conform to the city's building construction guidelines, with most spacing being 25 to 30 m, although the pairing of towers C2 and C3 would narrow to 20 m at the corners.

The site is located at a GO Transit station and is served by the Lakeshore GO Trains, MiWay, Oakville Transit and GO bus lines that operate along Southdown Road. (Block C is planned with the flexibility to accommodate a future bus loop with 14 spaces and five rest areas near the station entrance.) For cyclists, protected lanes are proposed for the new internal road with direct access to the Nine Creeks Trail.

There are other development activities in the area. Stonebrook Condominiums, an 18-story tower southeast of the train station, was completed earlier this year, marking one of the first high-rise additions in the area in about a decade. Further east along Royal Windsor Drive, a design for 2077 Royal Windsor calls for four towers of 25 to 35 stories.
As the proposal moves forward, Infrastructure Ontario is moving to the next phase of public consultation. Both virtual and in-person engagement sessions are scheduled for January 22 and 29, 2026.
