Erin Smith, Senior Heritage Planner, Heritage Planning, Urban Design, City Planning gave a presentation on 53 Strachan Avenue Entrance Address 805 Wellington Street West - Alterations to a Designated Heritage Property, Demolition of Heritage Attributes and Demolition of a Building under Sections 33 and 34(1)1 and 34(1)2 of the Ontario Heritage Act and Authority to Enter into a Heritage Easement Agreement.

This report recommends City Council approve the alterations and demolitions proposed under Sections 33, 34(1)1 and 34(1)2 of the Ontario Heritage Act for the Part IV designated heritage property known as Strachan House at 53 Strachan Avenue and the demolition of a building at entrance address 805 Wellington Street West, as well as grant authority to enter into a Heritage Easement Agreement.

The City-owned property contains the former Strachan House, one of the largest planing mills in Canada in 1888 when built for John B. Smith & Sons for processing rough-cut, seasoned lumber into smooth, finished dimensional lumber and millwork. After John B. Smith and Sons closed in 1967, the City leased the former factory building in 1989 to Homes First, who adaptively re-used it for supportive housing in 1996. Strachan House featured an innovative design by Levitt Goodman Architects based on an inclusive and collaborative process involving residents in its design. The property is currently vacant.

The subject application is associated with a City-initiated Official Plan and Zoning By-law Amendment application to redevelop the subject site as part of the Toronto Builds program with the goal of creating new affordable rental housing units on City-owned lands and re-establishing the supportive housing use on the site. The Official Plan requires that when a City-owned property on the Heritage Register is no longer required for its current use, the City will demonstrate excellence in the conservation, maintenance, and compatible adaptive reuse of the property.

The application proposes a 28-storey apartment building with 296 rental units (including 60 affordable rental units) at 53 Strachan Avenue, which includes conserving the Strachan House within the base of the redevelopment through the integration of its principal north and west facades and partial east and south facades by way of in-situ retention and dismantling and reconstruction. The 3-storey brick chimney smokestack located on the interior of the building is proposed to be reconstructed and other interior attributes that cannot be retained are proposed to be commemorated.

An 8-storey supportive housing building is proposed to replace the existing two-storey building known as the Maple Green Building at entrance address 805 Wellington Street West. The Maple Green Building was not identified in the property's statement of significance.

The combined applications under the Ontario Heritage Act propose to conserve the cultural heritage value and attributes of the Strachan House in accordance with the existing policy framework. The heritage impacts of the development proposal are appropriately mitigated through the overall conservation strategy.
