This report recommends that City Council approve an application under Section 42 of the Ontario Heritage Act to alter a designated heritage property at 530-550 Yonge Street, 6-8 Breadalbane Street and 145 St. Luke Lane, in connection with a Zoning By-law amendment application on the subject property, and that Council grant authority to enter into a Heritage Easement Agreement.

The south façade of the existing two-storey commercial building at 530-536 Yonge Street and 6-8 Breadalbane Street will be partially retained and incorporated into a new corner building with retail storefronts on the ground floor. The remainder of the existing building will be demolished. 145 St. Luke Lane is also proposed to be demolished as part of this proposal. A Privately-Owned Publicly Accessible Space (POPS) fronting on St. Luke Lane will replace the western portion of the existing building. A Heritage Impact Assessment prepared by ERA Architects Inc., dated January 2, 2025, was submitted to support the development application and revised July 17, 2025, and October 21, 2025.

Through revisions to the application, Heritage Planning staff are satisfied that the proposal conserves the designated heritage property and is consistent with the policy framework. The heritage impacts of the development proposal are appropriately mitigated through the overall conservation strategy of the retained buildings and design of the replacement buildings.
