What is Happening?

As part of improvements being made to the Barrie line and at Downsview GO Station, Metrolinx crews will be working over two weekends in May to carry out various construction activities, including culvert and trench box installations and shoring. This work will take place over the May 22-25 and May 29-June 1 weekends. Construction will be continuous, day and night, beginning on Friday night and ending by Monday morning. The work will be happening over two weekend service pauses of the Barrie GO line, so that crews can work safely on the track without live trains passing by.

What to expect

Construction lighting may be visible from the work site.
Where possible, lights from equipment will be positioned away from residential homes to keep light pollution levels low.
Trucks and construction equipment may generate dust during construction.
Crews will take precautions to monitor and reduce dust.
Increased presence of construction vehicles and equipment can be expected in the work area.
Work areas will be clearly marked or fenced off to ensure public safety.
Please exercise caution around active construction sites.
Work may be delayed or rescheduled due to weather or unforeseen circumstances.
Trucks will stage inside the work site and will not stage outside of the site boundaries

Traffic Changes

No disruptions to traffic are anticipated.

Pedestrian Access

All pedestrian sidewalks will remain open throughout the work.

Noise and Vibration

Residences and businesses in the area may experience noise and vibration caused by construction equipment related to this work.
Crews will take measures to minimize disruptions to the surrounding area wherever possible.
To minimize noise impacts on the community, noise and vibration monitoring equipment will be installed prior to construction. These devices will help to detect exceedances early to proactively conduct corrective actions as needed while crews work.
Trucks accessing the site will be equipped with broadband backup alarms, which emit a less disruptive sound compared to traditional beeping backup alarms.
