THE ARCHITECTURE AND HISTORY
Imperial Plaza at 111 St Clair Avenue West occupies one of Toronto's most celebrated mid-century commercial buildings: the former headquarters of Imperial Oil, designed in 1957 by Mathers and Haldenby in the International Style. The building was originally conceived as a submission for Toronto's new city hall design competition -- a pedigree that communicates the level of architectural ambition brought to its construction. When Imperial Oil relocated to Calgary, Camrost-Felcorp acquired and converted the building to residential use, a transformation completed in 2015 and recognised with a Heritage Toronto Merit Award.
The building's 23-storey limestone facade is one of the defining elements of the Yonge and St Clair streetscape. The conversion preserved the landmark exterior while introducing nearly 400 residential suites across the existing floor plates, creating a category of residence that exists nowhere else in Toronto: a soft loft in a mid-century modernist monument, with the ceiling heights, window proportions, and spatial qualities that a 1957 office building produces and that no purpose-built condominium can replicate.
Interior design by The Design Agency and OneSpace Unlimited carried the building's mid-century modernist language into the residential specification: contemporary European kitchens, hardwood floors, and the kind of spatial openness that a converted office floor plate delivers in contrast to the compact layouts of purpose-built residential construction.
THE RESIDENCES
Suite sizes at Imperial Plaza range from 485 to 5,001 square feet across nearly 400 residences -- a range that reflects the building's conversion from an office floor plate, which produces a fundamentally different suite typology than standard residential construction. Some units are two-level lofts with 2-storey windows stretching the full height of both storeys -- a spatial quality that is impossible to replicate in new construction at any price point. Others are contemporary open-concept flats with high ceilings and the clean lines of a mid-century building's structural logic.
The best suites at Imperial Plaza are among the most spatially distinctive residences in Toronto's midtown market. The combination of 1957 construction's generous structural bays, the 10-foot ceiling standard throughout, and the possibility of two-storey loft configurations produces a suite offering that is genuinely unlike anything available in the luxury condo market north of Bloor Street.
Suite interiors vary considerably, reflecting the building's decade of owner occupation. The best-renovated units at Imperial Plaza are finished to a high contemporary standard while preserving the proportional and material qualities of the original conversion. For the buyer who understands that the floor plate matters more than the finish -- and that the finish is something they can control -- Imperial Plaza's suite range offers extraordinary raw material.
THE AMENITIES
Imperial Plaza provides over 20,000 square feet of amenities, including an indoor pool and whirlpool, a full gym, a yoga and pilates studio, a golf simulator, two squash courts, a music studio, media rooms, a theatre, a games room, and a 24-hour concierge. The amenity program is one of the most extensive in the midtown market -- a function of the building's large unit count and Camrost-Felcorp's ambition for the conversion.
The ground-floor retail directly accessible from the building's lobby includes Longo's grocery, the LCBO, and Starbucks -- a retail offer that eliminates a significant proportion of the daily errands that most residents of standalone residential buildings must make by car or on foot. For the buyer who values operational convenience as part of their residential calculus, this combination of amenities and ground-floor retail is difficult to match in any midtown building.
PARKING AND LOCATION
Underground parking is available for residents. The building's Yonge and St Clair position -- at the intersection of two subway lines and in the heart of one of the city's most activated midtown commercial corridors -- means that the building has a transit score that makes vehicle ownership genuinely optional for most residents.
The building sits adjacent to Forest Hill South, Deer Park, Rosedale, and Yorkville -- a position that Camrost-Felcorp describes as being at the convergence of four of Toronto's most luxurious neighbourhoods. The walk to Forest Hill Village is manageable. The walk to Yorkville is a longer but achievable 15 minutes. The subway connection to Bloor and Yonge is two stops south, placing the building within the full range of midtown amenity access.
PETS
Pet policies at Imperial Plaza are governed by the condominium corporation's current rules. Buyers with animals should confirm current policies through the status certificate before purchasing. Nissan Michael can facilitate that review.
THE MARKET
Imperial Plaza occupies a category of its own in the midtown luxury market: a heritage-conversion soft loft building with suite sizes to 5,001 square feet, 20,000+ square feet of amenities, and ground-floor grocery, LCBO, and cafe access, all in a 1957 International Style landmark at Yonge and St Clair. The building's price range spans from entry-level suites in the smaller configurations to substantial two-level loft residences in the upper tier -- a range that reflects the diversity of the suite offering.
For the buyer who has found the purpose-built luxury condo market unable to produce the spatial quality they want, and who understands that the best residential spaces in this city often come from conversions and heritage buildings rather than new construction, Imperial Plaza is the midtown answer to that search.
