93 Ontario Street is proposed as a 16-storey mixed-use rental building within two Protected Major Transit Station Areas along the Ontario Line 3 to the east of Downtown Toronto. Designed by Sweeny &Co Architects for Colonia Treuhand Holdings, the project would rise at the northeast corner of Ontario Street and Richmond Street East in the Moss Park area.

The site is municipally addressed to 79, 81, and 93 Ontario Street which form an irregular L-shaped parcel. Existing conditions consist of a two-storey semi-detached residential building containing three rental units, alongside a surface commercial parking lot accessed from Ontario Street, with utility infrastructure and a registered Toronto Hydro easement located near the northern edge of the property. The site is within the broader King–Parliament district, where low-rise buildings, former surface parking lots, and legacy commercial uses are being steadily replaced by mid- and high-rise, mixed-use development.

The Planning Partnership has submitted a Zoning By-law Amendment application to the City of Toronto on behalf of the developer. The proposal envisions a single 16-storey mixed-use building rising 61.1m. A 4- to 6-storey podium, inclusive of a mezzanine level, would establish a streetwall condition.

The development would deliver 98 purpose-built rental units, comprising 57 one-bedroom units, 31 two-bedroom units, and 10 three-bedroom units. Total Gross Floor Area is proposed at 7,816m², including 7,738m² of residential space and 78m² of ground-floor retail located at the southwest corner. The Floor Space Index would be 8.57 times the 913m² assembly. 

Approximately 216m² of indoor amenity area would be provided, paired with about 157m² of outdoor amenities located at the upper levels alongside the mechanical and terrace space. Vertical circulation would be handled by two elevators, resulting in an elevator ratio of one per 49 units, indicating prompt service.

Below grade, the proposal includes a single underground level accommodating building servicing functions. No residential vehicular parking spaces would be provided. At grade, two pick-up and drop-off spaces are proposed alongside one loading space. Bicycle parking would total 110 spaces, comprising 90 long-term spaces for residents and 20 short-term spaces for visitors.

The under-construction Moss Park station is approximately 400m northwest, while Corktown station is also under construction, roughly 450m southeast. Existing nearby transit includes east–west streetcar service along Queen and King streets, while north–south bus routes operate on Parliament and Sherbourne streets. Active transportation infrastructure is immediately adjacent, as the Richmond Street East cycle track runs directly along the site frontage, offering protected east–west cycling connections.

To the south, nearby proposals include East Richmond at 43 storeys and 49 Ontario Street with towers of 46 and 50 storeys. Northwest of the site, applications at 245 and 225 Queen Street East would rise 25 and 37 storeys respectively, while ROQ City is under construction with towers reaching 24 and 33 storeys. To the east, proposals include 550 Adelaide Street East at 29 storeys, Berkeley House at 36 storeys, 494 and 517 Richmond Street East at 45 storeys, and 134 Parliament Street at 46 storeys. Further northeast, development activity includes 301 Queen Street East at 17 storeys, alongside taller proposals at 351 and 333 Queen Street East reaching 28 and 50 storeys.
