(ASI) was contracted by SNC-Lavalin Inc. to conduct a cultural heritage assessment as part of the Hurontario-Main Light Rail Transit (LRT) Preliminary Design and Transit Project Assessment Process (TPAP) study. The study corridor extends along Hurontario Street in the City of Mississauga from Park Street in Port Credit northerly to Steeles Avenue, and continues north along Main Street South/North to just south of Church Street West in the City of Brampton. In early 2014, Metrolinx joined the City of Brampton and the City of Mississauga as a co-proponent for the TPAP. The results of background historic research and a review of secondary source material, including historic mapping, revealed a study area with a rural land use history dating back to the early nineteenth century. Over the course of the twentieth century, the Hurontario-Main LRT study corridor has steadily urbanized with primarily a combination of residential, commercial and recreational land uses. A total of 24 built heritage resources and 12 cultural heritage landscapes were identified within the study area. The Hurontario-Main LRT study corridor may have a variety of impacts upon built heritage resources and cultural heritage landscapes. Impacts can include: direct impacts that result in the loss of resources through demolition or alteration, or the displacement of resources through relocation; and indirect impacts that result in the disruption of resources by introducing physical, visual, audible or atmospheric elements that are not in keeping with the resources and/or their setting. The following recommendations have been developed to inform development of detailed functional planning and route analysis of the proposed conceptual alignment for the Hurontario-Main LRT study corridor: 1. According to the Design Workbook 3 (DW3) drawings, the proposed Hurontario-Main LRT alignment has been designed to stay within the existing road right-of-way where possible. However, minimal encroachment will impact CHL 1 and identified heritage attributes. (i) CHL 1: As a result of the Mineola Road LRT Stop, encroachment will take place along the frontage of the two properties just south of Mineola Road West, on the west side of Hurontario Street. The property limits will be set back between one to three metres to accommodate the projected sidewalk. A few young trees and two brick pillars with concrete caps, located to either side of the north driveway into 1312 Hurontario Street, will be directly impacted by the projected sidewalk. Given that this is part of the Mineola Neighbourhood and thus listed on the Mississauga Cultural Heritage Landscape Inventory, a detailed heritage impact assessment should be conducted to determine the potential heritage value of these resources and to recommend appropriate mitigation options. An HIA should be conducted by a qualified heritage consultant at the earliest stage possible, preferably during preliminary design or otherwise in the early stages of detail design, and should be conducted for the purposes of confirming the specific heritage significance of a heritage resource and associated heritage attributes, and to provide appropriate recommendations. The HIA should follow the municipal HIA Terms of Reference, and consultation with heritage staff at the City of Mississauga. The completed HIA should be presented to the Municipal Heritage Committee and City Staff for comment, and approval, and the recommendations of the HIA implemented. Potential mitigation options are documentation and relocation of the trees and brick pillars further back on to the property. 2. The Britannia Cemetery (CHL 6) in Mississauga and the Cheyne Cemetery (CHL 8) in Brampton are Cultural Heritage Assessment Report – Assessment of Impacts Hurontario-Main LRT Preliminary Design and TPAP City of Mississauga and City of Brampton, Ontario Page iii located on the east side of Hurontario Street. (i) A Cemetery Investigation to determine the limits of the Britannia Cemetery (CHL 6) was recommended for the Hurontario/Main Street LRT TPAP by Archeoworks (2010). Given the sensitive nature of this cultural heritage resource, the cemetery limits should be flagged based on the results of the Cemetery Investigation and steps taken to ensure that the site and surrounding fence are retained and protected during construction-related activities. (ii) The Cheyne Cemetery (CHL 8) has previously been subject to a cemetery investigation (ASI 1991; 1992) which determined the western limits of the cemetery. Given the sensitive nature of this cultural heritage resource, the cemetery limits should be flagged based on the results of the Cemetery Investigation and steps taken to ensure that the site and surrounding fence are retained and protected during construction-related activities. 3. Based on a review of the DW3 drawings and the draft Noise and Vibration Impact Assessment for the Hurontario-Main Light Rail Transit (J.E. Coulter Associates Ltd 2013), the heritage resources identified as BHR 14, BHR 15, CHL 6 and CHL 12 may be affected by vibration impacts during the construction phase of the project. To mitigate these impacts, these cultural heritage resources should be monitored during heavy construction activity, whenever such activity occurs in the vicinity of the above identified resources. In addition, pre-construction building condition surveys of structures located in BHR 14, BHR 15, CHL 6 and along Main Street North in CHL 12 should be undertaken to determine if other measures in addition to monitoring is required to conserve these resources. 4. Indirect impacts to CHL 9 and CHL 12 are expected through disruption and alteration to the setting of these landscapes. As such, these resources should be subject to photographic documentation and compilation of a cultural heritage documentation report by a qualified heritage consultant in advance of construction. This requirement for CHL 9 and CHL 12 was recommended in the report prepared by UMA in 2010, and consequently, is part of the current ASI work plan. 5. Direct impacts to BHR 21, BHR 22 are expected as both bridges are to be altered through superstructure replacement. As such, a detailed Heritage Impact Assessment (HIA) should be conducted for the bridges at the Etobicoke Creek Crossing (north and south crossings) (BHR 21 and BHR 22) to determine the potential heritage value of these resources and to recommend appropriate mitigation options. An HIA should be conducted by a qualified heritage consultant at the earliest stage possible, preferably during preliminary design or otherwise in the early stages of detail design, and should be conducted for the purposes of confirming the cultural heritage value of these resources and if they are eligible for designation under Part IV of the Ontario Heritage Act, to identify associated heritage attributes, and to provide appropriate recommendations. The HIA should follow the municipal HIA Terms of Reference, and consultation with heritage staff at the City of Brampton. The completed HIA should be presented to the Municipal Heritage Committee and City Staff for comment, and approval, and the recommendations of the HIA implemented. 6. According to DW3 (received 23 October 2013), direct impacts to commercial buildings fronting on to Main Street North (CHL 12) are not expected to be directly impacted through removal at this time. However, should land takings be required in the future, particularly within the vicinity of the Queen Street northbound LRT stop and thus requiring the removal of any structures within the CHL 12 limits, a resource-specific Heritage Impact Assessment (as described in Recommendation #5) must be initiated as soon as possible. It should be noted that any changes to the current preliminary engineering drawings that result in removal/demolition of a building(s) in CHL 12 is not recommended from a cultural heritage point-of-view. 7. At present, the use of battery-operated vehicles instead of an Overhead Catenary System within the heritage area between Narwood Drive and the northern terminus of the study corridor has been proposed in the Main Street North corridor in downtown Brampton (CHL 9 and CHL 12). This is fully supported from a cultural heritage point-of-view given that it will decrease visual impacts to the Cultural Heritage Assessment Report – Assessment of Impacts Hurontario-Main LRT Preliminary Design and TPAP City of Mississauga and City of Brampton, Ontario Page iv setting and character of
