A change of ownership following the receivership of Vandyk Properties has led to a new development application to the City of Toronto for 39 Newcastle Street in South Etobicoke, with Osmington Gerofsky Development Corp. now steering the site forward. Designed by TACT Architecture, the proposal beside Mimico GO station calls for three rental towers ranging from 39 to 42 storeys on a triangular parcel on the southeast corner of Newcastle and Windsor streets.
The immediate context around the long-vacant lot is shaped by rail infrastructure and older low-rise employment buildings, while more recent townhouses and the GO station entrance are found to the west. Low-rise retail can be found along Royal York Road further west, while residential streets extend to all sides beyond the industrial and rail sites. Mid-rise and high-rise proposals and projects are beginning to replace the low-rise buildings around the site as well as south of the rail corridor and along Royal York Road.
The site has been the subject of multiple proposals and planning processes over the past decade. An early rezoning in 2017 sought three towers of 22, 30, and 36 storeys, but City staff recommended refusal for not aligning with the Mimico-Judson Secondary Plan. A revised application later secured LPAT approval in 2020 for three towers up to 36 storeys, though the by-law was never enacted. In 2022, the Province issued a Minister’s Zoning Order (MZO) tied to a Transit Oriented Community agreement with Metrolinx, allowing four towers of up to 36 storeys across 39 Newcastle and the adjoining rail lands.
Vandyk Properties advanced the plan under their Grand Central Mimico marketing banner that included 327 Royal York, submitting a site plan application in 2023, but financial collapse of the company brought all of that to a halt. By late 2023, the 39 Newcastle lands were placed in receivership at the request of Otera Capital, while neighbouring holdings at 327 Royal York also fell into receivership. Metrolinx, which had a partnership with Vandyk, dissolved it the following year, and an MZO for the site was repealed in 2024.
New developer Osmington Gerofsky has now submitted Official Plan and Zoning By-law Amendment applications to permit three towers rising 134.23m to 143.93m. Phase 1 would deliver the eastern 42-storey tower with 508 units above a five-storey podium, while Phase 2 would add the western towers with 1,070 units combined on a podium stepping from five to seven storeys. Together, the three buildings account for 1,578 rental suites and a total Gross Floor Area of 105,835m², broken down into 105,325m² of residential and 510m² of retail space. The plan yields a Floor Space Index of 13.41 times coverage of the 7,895m² property.
Retail would be focused at the northwest and southwest corners, positioned to activate the public realm, featuring a new 398m² central POPS (Privately-Owned Publicly-accessible Space) fronting Windsor Street. Amenity areas would entail 2,474m² indoors and 2,261m² outdoors, located at grade and the eighth floors of the towers. Each tower is designed with five elevators, working out to about one for every 102 units in Phase 1 and 107 units across Phase 2, requiring higher motor speeds for adequate service in the larger building.
Three levels of underground parking are planned, split between east and west garages to serve each phase. The garage would accommodate 406 parking spaces for residents and 19 for visitors, while cycling facilities would be divided into 537 long-term and 55 short-term spots.
Mimico GO station on the Lakeshore West line is less than 100m away. Local surface routes include the 80B Queensway and the 76B Royal York South buses stopping at Newcastle and Windsor. Cycling connections would be expanded with new bi-directional lanes on both frontages, tying into the Royal York bike lane and the broader Mimico-Judson network.
Several major projects are advancing around the GO station. To the northeast, plans include a 25-storey tower at 25 Audley Street and Grand Park Village with three towers ranging from 23 to 40 storeys. North of the site, 21–31 Windsor Street is proposed with four towers from 7 to 46 storeys. Northwest, proposals include Hälsa at 8 storeys, 430 Royal York at 9 storeys, and 464 Royal York at 12 storeys, while to the west, the Royal Art Collection Etobicoke is proposed at 11 storeys. Southwest, 327 Royal York Road is planned at 51 and 55 storeys.
