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 39-storey mixed-use condominium and low-rise commercial and live/work buildings. This development involves Blocks 5B, 5C, and 5D 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 contains 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.
The Site Plan Approval application for 158 Sterling Road outlines a 39-storey mixed-use condominium tower with a five-storey arm on Block 5B, and a low-rise commercial building on Block 5C. Block 5D would be part of landscaped and programmed open space on the site. The 39-storey tower, standing at 130m, would feature a five-storey podium and provide 30,256m² of residential Gross Floor Area (GFA) with 477 residential units, and a Floor Space Index (FSI) of 6.67. At grade, 603m² of retail is planned in the podium, along with ground level live-work units. Complementing this, the low-rise commercial building to the south, standing 9.28m, would encompass 963m² of non-residential GFA.
Plans include 954m² each of indoor and outdoor amenity space. The tower would be equipped with four elevators, or approximately one for every 119 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 142 parking spaces for residents and 25 for visitors and non-residential use. Bicycles would have 390 long-term spaces and 44 short-term spaces provided for them below grade, alongside 40 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 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.
