Anne Fisher, Program Manager, Heritage Preservation Services, Development Review, Urban Design, City Planning gave a presentation on 358-360 Dufferin Street (including structure address at 350 Dufferin Street) - Alterations to and Demolition of Heritage Attributes of Designated Heritage Property under Sections 33 and 34 of the Ontario Heritage Act and Authority to Enter into a Heritage Easement Agreement.

This report recommends that City Council approve the proposed alterations and demolitions under Sections 33 and 34 of the Ontario Heritage Act for the properties at 358-360 Dufferin Street (including structure address 350 Dufferin Street) and grant authority to enter into a Heritage Easement Agreement.

The subject properties comprise part of the Dominion Radiator Complex, a Late-Victorian era industrial compound defined by Factory Office buildings grouped around an open, central courtyard. The prominent Toronto architect, E.J. Lennox, is attributed to the adaptation and expansion of buildings on the site during Dominion Radiator's ownership (1889-1907). The functional industrial design of the Foundry, Mixing & Core Oven Buildings with their large footprints and the tall brick chimneys are typical Victorian industrial buildings. The site constitutes a cultural heritage landscape that facilitated heavy industrial manufacturing and contributed to the historic character of Parkdale.

This Heritage Permit application is in connection with an application to amend the Official Plan and Zoning By-law to permit three mixed use buildings with heights of 29, 26, and 9 storeys. The redevelopment achieves whole-building retention and re-use of the Mixing & Core Oven Buildings. The Factory Office and Foundry Buildings are to be partially retained within the new construction surrounding the central courtyard, which is to become re-animated as a Privately-Owned-Publicly Accessible-Space.
