Revised plans for a City-led affordable housing development at\u00a01113 through 1125 Dundas Street West<\/a> in Toronto\u2019s Trinity-Bellwoods neighbourhood are advancing through Site Plan Approval, following Official Plan Amendment and Zoning By-law approvals secured in 2024. Now designed by\u00a0Montgomery Sisam Architects<\/a> and\u00a0Moriyama Teshima Architects<\/a> for\u00a0CreateTO<\/a>, the mixed-use proposal, slated to begin construction in July, 2026, will bring a 10-storey mass-timber rental building with ground-floor retail to the south side of Dundas Street West just east of Ossington Avenue.\u00a0<\/p>\n The site is on the south side of Dundas between Ossington Avenue and Shaw Street, spanning 1113, 1117, and 1125 Dundas Street West. The property currently consists primarily of a City-owned Green P surface parking lot \u2014 which the Ossington BIA fought unsuccessfully not to lose \u2014 while a formerly vacant detached house at the eastern edge of the site has since been removed as part of early site preparation work. Located west of Trinity-Bellwoods Park, the area surrounding the site is characterized by a mix of low-rise residential streets, with a concentration of main street commercial storefronts, restaurants, bars, and independent retail, especially along Ossington Avenue to the south and Dundas Street to the west.<\/p>\n The proposal traces back to May, 2022, when City Council authorized the site as part of Toronto\u2019s Mass Timber Affordable Housing Pilot Program, intended to advance affordable rental housing alongside low-carbon construction methods on City-owned land. Initial plans were prepared through\u00a0Brook McIlroy<\/a>, with public consultations held in 2024 as the project moved through Official Plan Amendment and Zoning By-law Amendment applications. A revised submission filed in May, 2024 removed an earlier planned 3-storey laneway building, reducing the total unit count from 100 to 94 units while retaining the 10-storey main building. City Council later adopted the required planning approvals in July, 2024. Since then, the project has transitioned into the City\u2019s Toronto Builds framework, with CreateTO overseeing delivery alongside the Housing Development Office under the City\u2019s public builder model.\u00a0<\/p>\n The revised proposal will continue to bring a 10-storey, mixed-use, mass-timber building to the site, rising to 36m (slightly up from 35.5m), alongside a smaller 4m-tall ancillary structure. While the overall height and primary built form remain largely consistent, the latest plans refine the internal layout and reduce the unit count. Retail space will continue to animate the Dundas frontage.<\/p>\n The revised submission contains 74 rental units, down from the previously proposed 94. The updated unit mix eliminates studio apartments entirely, instead shifting toward larger suite formats with more family-sized housing through 42 one-bedrooms, 25 two-bedrooms, and 7 three-bedroom units (previously 18 studios, 56 one-bedrooms, 15 two-bedrooms, and 5 three-bedroom units). The affordable housing component remains with 28 affordable rental units.<\/p>\n Updated density figures show the project now with a total Gross Floor Area of 6,279m\u00b2, reduced from approximately 7,730m\u00b2 in 2023, producing a Floor Space Index of 3.7 times coverage of the 1,699m\u00b2 assembly. Of the total GFA, 6,079m\u00b2 is dedicated to residential uses, alongside 200m\u00b2 of retail space at grade. Amenities include 176m\u00b2 of indoor and 367m\u00b2 of outdoor area. Vertical circulation will be handled by two elevators, equating to one cab for every 37 residential units, indicating prompt response times.<\/p>\n The project continues as a mass-timber building under the City\u2019s affordable housing and low-carbon construction initiatives, incorporating onsite geothermal systems. No vehicular parking is proposed. Bicycle parking has been reduced from 105 to 86 spaces, comprising 68 long-term and 18 short-term spots.<\/p>\n The site is located along the 505 Dundas streetcar corridor which connects to both Bloor Line 2 and University Line 1, while the 63 Ossington bus is a short walk west, connecting to Bloor Line 2, and in the future to the under-construction\u00a0Ontario Line 3<\/a>, via Exhibition station<\/a>.<\/p>\n The proposal is one of a small number of redevelopment sites across the surrounding neighbourhoods. South of the site,\u00a028-36 Halton Street<\/a> is proposed at 4 storeys, while the\u00a0108 Harrison Shelter<\/a> proposal to the north would rise 3 storeys. Additional intensification is planned to the north along College Street, where proposals include the 6-storey\u00a0833 College<\/a>, the 9-storey\u00a0219 Roxton<\/a>, and the 14-storey\u00a0Costi House<\/a>.<\/p>\n UrbanToronto will continue to follow progress on this development, but in the meantime, you can learn more about it from our Database file, linked below.
