On May 15, 2024, the owner submitted a revised proposal for a 30-storey (99 metres, including mechanical penthouse) mixed-use building with retail at-grade, no office component, and 550 residential units. On July 9, 2024, the owner appealed to the Ontario Land Tribunal ("OLT") due to Council not making a decision on the application within the timeframe prescribed by the Planning Act. The property at 46 Spadina Avenue (including 40, 42, 44 and 50 Spadina Avenue) includes a 4-storey building that was constructed in 1907 with later additions in the 1940s. 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. 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 KSHCD, which was approved by Council on March 26 and 27, 2025. The owner now seeks Council's consent for revised alterations to the Systems Building. Council requires the advice of the Toronto Preservation Board in respect of matters which may impact a designated heritage property.
