Noise & Vibration

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: 

  • Identify receptor locations applicable for construction and operation.  
  • Assess construction and operation noise and vibration at receptors.  
  • Identify potential adverse impacts, determine the need for mitigation and provide a strategy or list of potential mitigation measures based on construction and operation plans. 

Existing Environmental Conditions

Toronto 

  • The Toronto segment is generally a mix between commercial and residential uses in a busy suburban environment.  
  • Dundas Street is an arterial roadway that is intersected by other major corridors (e.g., Kipling Ave and Highway 427) and minor residential or commercial access roads.  
  • The ambient sound levels at the most impacted noise sensitive locations (e.g., dwellings) are dominated by a combination of existing Dundas Street and the intersecting roads.  
  • Kipling station and the existing rail line is within approximately 300 m of sensitive locations but significant shielding from existing buildings lessen the noise contribution to the ambient sound level at sensitive locations.  
  • Currently, no known existing vibration concerns due to road traffic.

Mississauga East

  • The Mississauga East segment is generally a mix between commercial and residential uses in a busy urban environment.  
  • Dundas Street is considered an arterial roadway which is intersected by other arterials (e.g., Dixie Road) and minor residential or commercial access roads.  
  • The ambient sound levels at the most impacted noise sensitive locations (e.g., dwellings) are dominated by a combination of existing Dundas Street and the intersecting roads.  
  • Existing GO rail intersecting Dundas Street near Cawthra contributes to the existing ambient sound levels at sensitive locations.  
  • Currently, no known existing vibration concerns due to road traffic. However, heritage buildings have been identified in close proximity to Dundas Street.  

Mississauga West

  • The Mississauga West segment is generally a mix between commercial and residential uses in a busy urban environment.  
  • Dundas Street is considered an arterial roadway which is intersected by other arterials (e.g., Mavis Road) and minor residential or commercial access roads.  
  • The ambient sound levels at the most impacted noise sensitive locations (e.g., dwellings) are dominated by a combination of existing Dundas Street and the intersecting roads.  
  • Currently, no known existing vibration concerns due to road traffic. However, heritage buildings have been identified in close proximity to Dundas Street.
