Consultant shall be entitled to rely upon the accuracy and completeness of information that was provided to it and has no obligation to update such information. Consultant accepts no responsibility for any events or circumstances that may have occurred since the date on which the Report was prepared and, in the case of subsurface, environmental or geotechnical conditions, is not responsible for any variability in such conditions, geographically or over time.

The study area consists of a 500 metre (m) wide corridor centered on Stouffville Road, from Highway 404 west to Yonge Street, and an approximate 100 hectare (ha) parcel of land where Stouffville Road terminates at Yonge Street (Figure 1 and Figure 2). The study area is located within multiple lots and concessions in the Geographical Townships of Whitchurch, Markham, Vaughan, and King South, now the Town of Richmond Hill, Municipality of York, York County, Ontario. This Stage 1 archaeological assessment was triggered by a Municipal Class Environmental Assessment during the planning stage of the project and to meet the requirements of the Environmental Assessment Act (Ontario Government 1990a). This project is also subject to the Ontario Heritage Act (Ontario Government 1990b). The Stage 1 archaeological assessment has determined that there is high potential for the recovery of both First Nation and Euro-Canadian archaeological resources within parts of study area and a known archaeological site is within its limits. Due to extensive urban development some portions of the study area have been previously disturbed; however, areas of agricultural field, woodlot, and manicured lawn within the study area limits are included as areas where archaeological integrity could remain intact (Figure 6). Stage 2 archaeological assessment is recommended for any areas of potentially undisturbed lands identified in this study as retaining archaeological potential. It should be noted that this Stage 1 assessment is a preliminary study completed during the early pre-planning stages of the Stouffville Road Improvements project and includes lands in which several different routing options are being explored. Once all route alternatives and the overall scope of this project have been determined, all areas of potentially undisturbed lands that may potentially be affected by this project will require Stage 2 archaeological assessment. The Stage 2 archaeological assessment must be conducted by a licensed archaeologist and must follow the requirements set out in the Standards and Guidelines for Consultant Archaeologists (Ontario Government 2011), including: Pedestrian survey at 5 m intervals where ploughing is possible (e.g., agricultural fields). This assessment will occur when agricultural fields have been recently ploughed, weathered, and exhibit at least 80 % surface visibility; Test pit survey at 5 m intervals in all areas that will be impacted by the project and where ploughing is not possible (e.g., woodlots, overgrown areas, manicured lawns); Poorly drained areas, areas of steep slope and areas of previous disturbance (e.g., pipelines, railways, road ROWs, buildings) identified are to be mapped and photo-documented, but are not recommended for Stage 2 survey as they possess low to no archaeological potential. During the background research, a historic church and cemetery were identified in the southwestern portion of the study area. Special consideration and recommendations must be made for the St. John’s Anglican Church and St. John’s Cemetery as historic churches and associated cemeteries significantly increase the potential for finding unmarked burial locations, grave shafts, and/or the recovery of human remains. Given the mid-19th century establishment of the registered St. John’s Cemetery, and its proximity to the Yonge Street Municipal ROW, a high probability exists that unmarked graves and associated shafts may be present adjacent to, or within the ROW. Current fence line or boundaries do not necessarily represent the limits of the cemetery below ground. As a i AECOM York Region Stage 1 Archaeological Assessment Stouffville Road EA precautionary measure, it is recommended that after Stages 1 and 2 archaeological assessments are completed, should any ground disturbing activities be conducted in the vicinity of the historic church, the following activities must be conducted to determine if any grave shafts are present: Stage 3 mechanical topsoil removal must be conducted for all lands
