In the ever-evolving Junction Triangle neighbourhood of Toronto, Marlin Spring Developments has proposed a high-rise complex at 158 Sterling Road. The project, designed by Giannone Petricone Associates is part of the broader Sterling Master Plan, and comprises a 31-storey mixed-use condominium and low-rise commercial and live/work buildings. This development involves Blocks 5B and 5C on the south side of Sterling Road and Perth Avenue.
The site is currently a mix of vacant land and a surface parking lot, and occasionally used as a staging area for adjacent construction activities. Situated in the northwest portion of the Sterling Master Plan, the larger site is bordered by Perth Avenue to the north, Sterling Road to the north and east, and the West Toronto Railpath to the west. Within Metrolinx's Bloor-Dundas Mobility Hub area, the surrounding blocks contain low and medium-rise residential, commercial, and industrial uses.
The Sterling Master Plan envisions a comprehensive, mixed-use redevelopment of the Junction Triangle, structured around an expanded network of public and private streets. Divided into five general development blocks, it would include new public parkland and POPS (Privately-Owned Publicly-accessible Space). The master plan proposes a new L-shaped private road within the site plus new private laneways. It aims to deliver retail, residential, daycare, office, and park uses, including the House of Assembly at 201 Sterling Road currently under construction, while the T3 Sterling Road commercial buildings were completed in the last year. The restored Tower Automotive Building is the centrepiece of the area, and is the new home of the Museum of Contemporary Art Toronto Canada, and the offices of Zeidler Architecture.
A Site Plan approval application from May 30, 2024 proposed a 39-storey tower standing 130m tall with 477 residential units. On June 25, 2024, however, a combined Official Plan Amendment and Zoning By-law Amendment application saw a reduction in these numbers for the latest iteration of the proposal.
The design now outlines two components. Block B calls for a 31-storey mixed-use condominium tower with a five-storey podium arm along Perth Avenue, containing 396 residential units for a total residential Gross Floor Area (GFA) of 24,804m² and non-residential GFA of 862m². Its Floor Space Index (FSI) would be 5.58. Block C to the south would contain a single-storey commercial building with 978m² of non-residential GFA. In total, 1,840m² of retail is planned for the podium, along with ground level live-work units.
Plans include 798m² of indoor and 594m² of outdoor amenity space. The tower would be equipped with three elevators, or one for every 132 units, indicating longer than normal wait times. A POPS would feature in the space between the complex's two arms.
A two-level underground garage would offer 147 parking spaces for residents and 21 for visitors and non-residential use. Bicycles would have 357 long-term spaces and 50 short-term spaces provided for them below grade, alongside 37 long-term and 14 short-term spaces above grade.
Situated between Bloor Street West and Dundas Street West with bus and streetcar service, the site is within walking distance to both Lansdowne station and Dundas West station on Bloor Line 2, plus the Bloor GO/Union Pearson Express (UPX) station. As part of the Metrolinx GO Expansion Program, the area will benefit from service upgrades on existing lines, while another GO station is planned near Bloor and Lansdowne, which would provide additional transit options upon its completion, anticipated in November 2027.
There are other redevelopment proposals in the area. To the north, 221 Sterling Road calls for three towers ranging from 20 to 29 storeys, 72 Perth Avenue is set to rise 16 storeys, 1439 Bloor Street West is 14 storeys, 1425 Bloor Street West is 20 storeys, the Sterling Automotive building is 19 storeys, and 1319 Bloor Street West is proposed at 31 storeys. To the west, 2280 Dundas Street West is set to transform the existing shopping centre south of Dundas West station into a mixed-use complex featuring seven buildings, ranging from 6 to 38 storeys.
