This project is following the Transit Project Assessment Process (TPAP) as defined in Ontario Regulation 231/08 under the Environmental Assessment Act. Cultural heritage is identified as a matter of provincial importance under the TPAP. Under the TPAP, the proponent is required to consider whether its proposed transit project could have potential negative impact on a matter of provincial importance as defined under Ontario Regulation 231/08 or on a constitutionally protected Aboriginal or treaty right. Metrolinx, as a prescribed public body under Ontario Regulation 157/10, is required to follow the Standards and Guidelines for the Conservation of Provincial Heritage Properties, prepared under Section 25.2 of the Ontario Heritage Act, when making any decisions affecting cultural heritage resources on lands under their ownership or control. In 2018, Stantec was retained by Metrolinx to conduct an assessment of built heritage resources and cultural heritage landscapes for the Stouffville Rail Corridor Grade Separations Project (the Project) located in the City of Toronto and City of Markham, Regional Municipality of York, Ontario. A Cultural Heritage Report: Existing Conditions and Preliminary Impact Assessment (Cultural Heritage Report) was undertaken to understand and describe the existing conditions within and adjacent to the Project Footprint, identify known and potential built heritage resources and cultural heritage landscapes, make a preliminary assessment of potential impacts, and provide mitigation options to address these impacts. No potential built heritage resources or cultural heritage landscapes were identified within the Cultural Heritage Study Area. Given that no potential built heritage resources or cultural heritage landscapes were identified, no impact assessment or recommendations are required. Therefore, no further cultural heritage studies are required for the Cultural Heritage Study Areas in accordance with Project requirements. The Executive Summary highlights key points from the report only; for complete information and findings, the reader should examine the complete report. i This page intentionally left blank Stouffville Rail Corridor Grade Separations Project – Cultural Heritage Report: Existing Conditions and Preliminary Impact Assessment Table of Contents Executive Summary ....................................................................................................... i Project Personnel .......................................................................................................... v Abbreviations ............................................................................................................... vi 1.0 Introduction ...................................................................................................... 1.1 1.1 Project Overview ............................................................................................... 1.1 1.1.1 Study Purpose and Objectives .......................................................... 1.5 1.2 Study Areas ....................................................................................................... 1.6 2.0 Methodology .................................................................................................... 2.1 2.1 Regulatory Requirements .................................................................................. 2.1 2.2 Screening Methodology ..................................................................................... 2.3 3.0 Existing Conditions ......................................................................................... 3.1 3.1 Background and Historical Research ................................................................ 3.1 3.1.1 Denison Street and Kennedy Road—Township of Markham ............ 3.2 3.1.2 Passmore Avenue, McNicoll Avenue, Huntingwood Drive, Havendale Road and Progress Avenue—Township of Scarborough ...................................................................................... 3.7 3.2 Government and Agency Data Requests ........................................................ 3.21 3.3 Identification of Known and Potential Built Heritage Resources and Cultural Heritage Landscapes ......................................................................... 3.22 4.0 Preliminary Impact Assessment .................................................................... 4.1 4.1 Description of Proposed Undertaking ................................................................ 4.1 4.2 Identification of Preliminary Potential Project Specific Impacts.......................... 4.1 5.0 Recommendations .......................................................................................... 5.1 6.0 References ....................................................................................................... 6.1 iii Stouffville Rail Corridor Grade Separations Project – Cultural Heritage Report: Existing Conditions and Preliminary Impact Assessment List of Figures Figure 1.1: GO Transit Networks .............................................................................. 1.1 Figure 1.2: Project Location ...................................................................................... 1.3 Figure 1.3: Cultural Heritage Study Areas -
