Study Highlights

Location of four sensitive receptors for baseline condition monitoring

  • Reviews construction and stationary sources of sound that will be produced from the Project
  • Study Area extends 500 m from Project Site
  • Construction phase was modelled based on construction activities and assumed equipment that will likely be utilized for the Project
  • Operations phase was monitored on stationary noise and vibration sources for the layover-built scenario
  • Baseline conditions at four identified representative sensitive receptors have been measured for a total of one month
  • Major sources of existing noise include rail traffic from CN freight, VIA Rail, GO trains, and road traffic
  • During construction, noise increases are anticipated to be temporary in nature and considered short-term nuisance to nearby residents

Potential Effects, Mitigation and Monitoring Measures

Potential Effect 1: The predicted sound indicate that it is feasible to operate most construction equipment within MECP limits.

Proposed Mitigation Measures

The following are recommended to reduce construction noise effects: 

  • Major construction activities scheduled during daytime hours. 
  • Noise mitigation measures (e.g., muffler systems) will be installed on construction equipment and properly maintained.
  • Where possible, construction equipment will be turned off when not in use (e.g., a no idling policy).
  • Vehicles and equipment should be routinely maintained and serviced for proper operation.

Proposed Monitoring Measures

  • Construction activities will be monitored by a qualified Environmental Inspector.

Potential Effect 2: Vibration levels from the construction equipment are not expected to affect the receptors in the Study Area.

Proposed Mitigation Measures

Due to the proximity of the construction footprint to surrounding sensitive receptors, further recommendations for mitigation of construction vibration include: 

  • Operate vibration-generating equipment as far from sensitive receptors as possible. 
  • Schedule vibration-generating activities so that they do not occur at the same time. 
  • Avoid use of impact pile-drivers and vibratory rollers near sensitive areas.

Proposed Monitoring Measures

  • Construction activities will be monitored by a qualified Environmental Inspector.
