What Work is Taking Place?

  • Geotechnical instrumentation and monitoring is required for the protection of the existing buildings and underground utilities by monitoring movements of the ground, support of excavation, utilities, structures and groundwater regime, prior, during and following construction in order to assess the need for implementation of mitigation measures.
  • Crews will drill approximately 15+ boreholes in the Cedarvale Station area to install geotechnical instrumentation and monitoring equipment. 


  • Work is expected to begin in early October 2016 and is expected to be completed within two months.
  • Work is permitted: 

9:00 AM to 4:00 PM, 7 days a week 
8:00 PM to 3:00 AM, 5 days a week, from October 17th to November 30th 
11:00PM to 5:00AM on October 17th and 18th 

  • All work will be prioritized for day-time hours. Overnight work (between 8:00 PM and 5:00 AM) may be required only as a contingency should traffic conditions during the day require the City to move the work to overnight hours.
  • The contractor may not always work during the permitted hours, but may do so at its discretion.
  • Work is subject to permits and all relevant approvals, and may be rescheduled due to weather conditions or unforeseen circumstances.

What to Expect

  • Equipment and work trucks will be present along the Eglinton Avenue West corridor, between Park Hill Road and Strathearn Road, on Wembey Road, in Ben Nobleman Park and on Allen Road just north of Eglinton, as crews move from one hole to the next.
  • Nearby residents and businesses can expect to hear noise related to drilling, saw-cutting, hydro-vaccing, and the use of heavy equipment. 

Short-Term Traffic & Pedestrian Details

  • Existing pedestrian walkways and property access will be maintained at all times.
  • As always, please take care when travelling near work sites.
