What is Happening?
Metrolinx crews will be installing three culverts under the track within the Barrie rail corridor during a weekend service pause (Major Track Closure) of the Barrie GO line from May 1-4, 2026. This work will occur continuously, day and night, beginning at 10:00 p.m. on Friday, May 1 and ending at 5:00 a.m. on Monday, May 4. Service along the Barrie line will resume on Monday morning after the work has been completed.
These infrastructure improvements are an essential step in bringing increased service to the line. By carrying them out over a weekend MTC, our crews are able to work on the tracks safely and without interruption from live trains. We understand that night works are not ideal and will do our best to mitigate any impacts to the surrounding communities.
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 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.
Transit Service
The Barrie GO rail line will be closed for the duration of the work. Signs will be posted to keep residents informed.
