Built Heritage Resources & Cultural Heritage Landscapes

← Return to the Environmental Conditions Report studies

Key Findings

During the cultural heritage existing conditions inventory work, 283 built heritage resources and cultural heritage landscapes, including Heritage Conservation Districts, were identified in the Study Area. Ontario Line West (OLW) has the most known, previously identified and potential heritage resources (139), followed by Ontario Line South (OLS) (121) and Ontario Line North (OLN) (23).

Identified built heritage resources are mainly concentrated:

  • In OLW, in the Exhibition Place area and throughout the downtown areas along Queen Street West, Richmond Street West, Adelaide Street West, King Street West, and Wellington Street West
  • In OLS, along Pape Avenue, in the Distillery District, and within the downtown area along Queen Street East, Adelaide Street East and King Street East
  • In OLN, along Pape Avenue and at Eglinton Avenue East and Don Mills Road

Notable built heritage resources and/or cultural heritage landscapes include:

  • In OLW, Exhibition Place and Fort York National Historic Site
  • In OLS, Osgoode Hall, Old City Hall, Distillery District, Massey Hall and Trinity Square
  • In OLN, Ontario Science Center and William Burgess Public School

Spotlight Case

Located on the north side of Gerrard Street East, west of Carlaw Avenue, Fire Station #324 is the only Toronto fire station built in the Art Deco style. Built in 1931, the two-story buff brick fire hall has a number of Art Deco features including a decorative stone frontispiece (combination of elements that decorate the main building entrance) with fire and lightning bolt detail.

Methods

A Cultural Heritage Report: Existing Conditions and Preliminary Impact Assessment identifies existing baseline cultural heritage conditions, including a historical summary of the development of the Study Area and an inventory of all known or potential built heritage resources and cultural heritage landscapes in the Study Area. The report also describes a range of potential impacts and mitigation measures – ‘preliminary’ heritage impact assessment based on current project knowledge.

Metrolinx will request the Minister of Heritage, Sport, Tourism and Culture Industries’ Consent where potential impacts include demolition or removal of any buildings or structures on a known or potential provincial heritage property of provincial significance or transfer of the property, in its entirety or partially, out of provincial control.

 

Preliminary Potential Impacts & Mitigation Measures for Further Study

The Cultural Heritage Report identified all known and potential built heritage resources and cultural heritage landscapes in the broad Ontario Line study area. It is expected that the number of built heritage resources and cultural heritage landscapes that may be impacted will be significantly reduced once a preferred alignment has been identified and/or detailed design has commenced. Impacts and mitigation measures will be confirmed and/or changes will be identified during detailed design. All that information will then be documented in a Heritage Detailed Design Report.

Construction

Potential Impacts

  • For each property, the report presents a range of potential impacts and alternative mitigation options ordered from most to least preferred, from avoidance to demolition or removal. Avoidance is the preferred option. Demolition or removal is to be considered as a last resort and only when no other options are viable.

Potential Mitigation Measures

  • Potential mitigation measures will vary based on the potential impact. Examples of potential mitigation measures include:
    • Review of the Project design to avoid impacts to property
    • Limit encroachment as close to the property line as possible to minimize impacts to the building and/or heritage attributes
    • For retention and reuse of the building, complete an Adaptive Reuse Study to document the heritage attributes and plans for minimizing impacts
    • For relocation/demolition, complete a structural engineering assessment, complete detailed documentation of the property including salvageable materials and/or heritage attributes, and during design, incorporate commemoration signage in consultation with the City of Toronto Heritage Preservation Services

Operations

  • No impacts to built heritage resources and cultural heritage landscapes are anticipated as a result of operations

Future Studies

  • As part of the Environmental Impact Assessment Report, a Heritage Detailed Design Report will be prepared once a preferred alignment has been identified and/or detailed design has commenced.
