350 Bloor Street East - Alterations to a Designated Heritage Property

Parkin. It features an identical expression on its principal (south), west and north elevations with a flat roof and precast concrete cladding that creates wedge-shaped columns and deep inset window openings above a recessed, transparent base. The property is designated under Part IV, Section 29 of the Ontario Heritage Act and the precast concrete cladding panels are identified as heritage attributes of the building in the designation by-law 799-2023. City Planning staff are currently reviewing development applications to permit a 63-storey mixed-use building, containing 806 dwelling units and 600 square metres of non-residential gross floor area at this property. This proposal includes reinstating the existing pre-cast concrete cladding as part of a six-storey podium for the new building. To determine the feasibility of this proposal, the developer proposes to temporarily remove three panels from the north façade, which faces the Rosedale Valley. The application that is the subject of this report is for approval under the Ontario Heritage Act for the temporary removal of these panels to allow for testing the feasibility of re-using the cladding within the base design of the current development applications. The areas where the panels are removed would be temporarily infilled with timber framing and plywood, and the original panels would be reinstalled by the end of August 2024. Heritage Planning staff support the proposal but are asking that conditions be attached to the approval under the Ontario Heritage Act that will allow City Council to require the reinstatement of the panels within a reasonable time frame and to an appropriate conservation standard. Approvals for the related development application will be reported to the Toronto Preservation Board and Council on at a future date.
