46 and 58 Spadina Avenue and 378 Wellington Street West - Alterations to and Demolition of Buildings at Heritage Properties Designated Under Part V of the Ontario Heritage Act

It is known as the "Systems Building" and is identified as a contributing Industrial/Commercial building within the King-Spadina Heritage Conservation District (KSHCD) Plan. The properties at 58 Spadina Avenue (including 60 Spadina Avenue) and 378 Wellington Street West are non-contributing properties in the KSHCD Plan. An Official Plan and Zoning By-law Amendment application for the subject properties was received in August 2022 for the construction of a 28-storey mixed-use building with a 4-storey podium featuring commercial retail at-grade and 521 dwelling units in a new residential tower. The applicant subsequently appealed this application to the Ontario Land Tribunal (OLT) due to Council not making a decision within the time frame prescribed in the Planning Act. Revised plans have been submitted by the applicant with prejudice, as reflected in this report. On July 16, 2024 the applicant submitted an application under Section 42 of the Ontario Heritage Act to alter the designated Systems Building and demolish three small adjacent buildings to allow for the construction of a new 30-storey mixed-use building within the King-Spadina Heritage Conservation District. The proposal will feature in-situ retention of the entire primary east façade, the eastern portion of the south façade and a partial west return wall of the Systems Building at 46 Spadina Avenue. The eastern portion of its north façade will be partially reconstructed. The remainder of the Systems Building as well as two small outbuildings to its north will be demolished to allow for the construction of a 30-storey tower. The tower is set back 4.9-5.4m from the front façade along Spadina Avenue and 3.12m from the south façade. The non-contributing building at 58 Spadina Avenue is also proposed to be demolished. The proposed development is consistent with the existing provincial and municipal heritage policy framework and proposes an overall conservation strategy that is consistent with the KSHCD Plan and is not contrary to the Plan's Objectives.
