150 College Street (Medical Sciences Building - 1 King's College Circle) - Alterations to a Designated Heritage Property under Section 33 of the Ontario Heritage Act and Authority to Enter Into a Heritage Easement Agreement

The Medical Sciences Building complex is located at the southeast portion of King's College Circle, between King's College Road and Queen's Park Crescent West, on the University of Toronto's St. George Campus. The property is designated under Part IV, Section 29 of the Ontario Heritage Act (OHA) through Designation By-law 84-2026 and currently houses the Temerty Faculty of Medicine and affiliated student programming. Constructed between 1966 and 1970, the Medical Sciences Building is characterized by its asymmetrical massing, generally ranging between three and seven storeys, and its highly sculptural precast concrete panel cladding, designed by Canadian artists Robert Downing and Ted Bieler and the fabricator, Beer Precast. The subject property is a significant example of the University of Toronto's post-war expansion and is recognized as a landmark within both the campus and the City of Toronto. The proposal involves the rehabilitation of the Medical Sciences Building complex to support its continued use as a centre for leading-edge biomedical research. The proposed rehabilitation will introduce open-concept research, teaching, and social spaces to support collaboration and interdisciplinary work. The proposal includes the demolition of the western-most wing (Wing B) and its replacement with a nine-storey multipurpose building, with a two-storey mechanical penthouse. The replacement building will accommodate new laboratory spaces, modernized teaching facilities, collaborative workspaces, and administrative offices. The impacts of the proposed development on the heritage property and adjacent heritage resources are appropriately mitigated through the overall conservation strategy and the compatible, yet distinguishable, design of the new building. Heritage Planning staff are satisfied that the proposed alterations conserve the cultural heritage value and attributes of the property and are consistent with the applicable policy framework.
