Neil MacKay, Heritage Planner, Heritage Planning, Urban Design, City Planning gave a presentation on 405 Sherbourne Street - Alterations to a Designated Heritage Property under Section 42 of the Ontario Heritage Act.

This report recommends that City Council approve the alterations proposed for the designated heritage property municipally known as 405 Sherbourne Street under Section 42 of the Ontario Heritage Act, in connection with a proposed development of the subject property. The Zoning By-law Amendment application is subject to a Heritage Permit application under the Ontario Heritage Act, as the subject site is designated under Part V of the Ontario Heritage Act as part of the Cabbagetown Northwest Heritage Conservation District.

The proposed development application for the subject site contemplates the construction of a 35-storey mixed-use building, replacing an existing surface parking lot. This is a City-owned property that is part of the City Council directed Toronto Builds (formerly Housing Now) initiative to develop housing, including affordable housing, on City-owned land.

In July 2021, City Council approved a Zoning By-law Amendment Application to permit a 25-storey mixed-use building on the subject site. The new Zoning By-law Amendment application has been submitted to allow for additional density on the site and to permit a built form that allows for additional two and three-bedroom units to be provided.

The impacts of the proposed development on the Cabbagetown Northwest Heritage Conservation District are appropriately mitigated through the compatible design of the new construction. The proposal will serve the public interest by providing 301 new rental housing units (including up to 90 affordable housing units) and 229 square metres of community space on the ground floor.
