Archaeology

Study Method

The purpose of the environmental studies are to:  

  • Establish existing (baseline) conditions;  
  • Identify and characterize existing features;  
  • Complete impact assessments; and  
  • Develop measures to avoid, minimize or mitigate potential negative effects.  

Methods undertaken to complete these studies include the following: 

  • Visual inspection.  
  • Examine historical and archaeological data, including:  
    • Recent and historical maps of the study area;  
    • Previous archaeological assessments within 50 metres of the study area;  
    • The Ministry of Heritage, Sport, Tourism and Culture Industries (MHSTCI) Archaeological Sites Database; and  
    • Archaeological management plans or other archaeological potential mapping, where available.  
  • Identify potential adverse impacts and appropriate mitigation measures.  

Existing Environmental Conditions

Toronto 

  • Three registered archaeological sites were identified within one km of the current project area boundaries.  
  • A visual inspection to confirm areas of archaeological potential versus areas of urban disturbance found that the project area consists primarily of residential and commercial development along Dundas Street West from the Toronto/Mississauga boundary at Etobicoke Creek to just west of Highway 427. The inspection also found that some areas may retain archaeological potential, requiring a Stage 2 archaeological assessment to confirm disturbance or search for archaeological materials.  
  • Results of the Stage 1 background research and field review, including mapping and determination of archaeological potential will be summarized in the Stage 1 archaeological assessment report. 

Mississauga East

  • Three registered archaeological sites were identified within one km of the current project area boundaries.  
  • A visual inspection to confirm areas of archaeological potential versus areas of urban disturbance found that the project area consists primarily of residential and commercial development along the Dundas Street East corridor, roadways and highways (e.g., Confederation Parkway, Hurontario Street and Dixie Road), with some areas of manicured lawn and park land.  
  • Results of the Stage 1 background research and field review, including mapping and determination of archaeological potential, will be summarized in the Stage 1 archaeological assessment report.

Mississauga West

  • Eleven registered archaeological sites were identified within one km of the current project area boundaries.  
  • A visual inspection to confirm areas of archaeological potential versus areas of urban disturbance found that the project area consists primarily of residential and commercial development along the Dundas Street East corridor, roadways and highways (e.g., Highway 403, Erin Mills Parkway, Winston Churchill Boulevard and Mavis Road), with some areas of manicured lawn and park land.  
  • Results of the Stage 1 background research and field review, including mapping and determination of archaeological potential, will be summarized in the Stage 1 archaeological assessment report.
