GO Expansion

GO Rail Expansion Will Enable:

3x more trips from 3500 weekly trips in 2019.

Electric trains accelerate and decelerate faster. Introduction of additional express services.

No need to check a schedule with service averaging every 15 minutes.

graphic of lanes of traffic

Doubling regional commuter capacity equivalent to nine highways the size of the 401.

More trains = reduced congestion across the region, taking close to 145,000 car trips per day, off the road.

An estimated 8,300 annual jobs created for the first 12 years of delivery will be created over the lifecycle of the program.

All operating costs covered with fare box revenue. GO Rail revenues will exceed 110% of operating costs over the next 60 years.

graphic of transit riders

More options and faster trains will increase peak and off-peak service. By 2055, annual ridership will exceed 200 million.

What are we Doing?

Metrolinx GO Expansion Program

Metrolinx is working to transform the way the region moves by building a seamless, convenient and integrated transit network across the Greater Golden Horseshoe. Over the next 10 years, Metrolinx is transforming the existing GO rail system to deliver a whole new rapid transit experience to your community. With more frequent train service you will have more options to get where you need to go.

Barrie GO Line Expansion

The Barrie GO Line Expansion will bring all-day, two-way GO service for people across Toronto, York Region and Simcoe County.

two-way service, all-day service, up to every 15 minutes

The Process

Graphic displaying the project process. The GO Expansion Program started in 2014 and improved rail service in both directions, on five of the seven GO rail corridors, including Barrie Corridor. Next, the Barrie Rail Corridor Expansion Transit Project Assessment Process started in 2015 and was in 2017. The Study identified specific and appropriate rail corridor infrastructure improvements needed to support an increased level of GO train service, including: Double Track, GO Station Upgrades, Existing Structure Upgrades, New Train Layover Facility. Three (3) Public Meetings were held to incorporate public feedback. Next, Barrie Double Track-Enabling Works started in 2020 and completion is planned for 2024. Last, Barrie Double Track Construction is planned for the future.

The Project

Barrie Double Track-Enabling Works (the Project)

The Project includes modifications and upgrades to the existing rail corridor, that will allow for a second set of  tracks to be installed in the future. The Project Area is within the City of Toronto, and is organized into seven  zones. Different zones will be constructed at different times, between 2020 and 2025.

Zone 5 is west of Lawrence Avenue West, Zone 4 is west Calendonia Station, Zone 3 is west of St. Clair Avenue West, Zone 2 is west of Davenport Road, Zone 1 is west of King St. West. Zones 7-4 and zones 3-2 are separated by Caledonia Station, Zone 2 and Zone 1 are separated by Davenport Diamond.

Zone 2

Davenport to St. Clair work includes:

  • Clearing and Grubbing
  • Grading and Drainage
  • Noise Barrier Wall with Anti-Graffiti Coating
  • High Security Fence
  • Utility Relocation and Protection

3 & 4. Noise Barrier Wall Construction

  • Removal of existing vegetation (clearing and grubbing).
    • Some private trees will require trimming or removals. Removal trees will be compensated according to City of Toronto's by-law.
    • Residents will be advised of any removals a minimum of 2 weeks in advance. 
    • Metrolinx will contact directly any affected property owners where private tree removals are required.
  • Grading the ground and preparing to install retaining walls and other infrastructure.
  • Installation of noise barrier wall posts and panels.

  • Delivery and placement of gravel material in the rail corridor.
  • Relocation of utilities and upgrades to drainage infrastructure, including culvert and sewer works.
  • Installation of security fences.
  • Stabilization and restoration of the disturbed soils.

Traffic Circulation:

  • All work will be done within the rail corridor, with designated access points for construction staff.
  • There should be minimal impacts to traffic.

Noise and Vibration

Expect perceivable noise and vibration that is typical of construction activities. Noise levels managed to be within regulatory requirements. Vibrations levels assessed to be below what could damage property. Mitigation measures include, but not limited, to minimizing drop heights, idle reduction, and use of temporary sound barriers.  


Mitigation measures will be applied for dust suppression include, but not limited to, limits on stockpile heights and the use of vacuum sweeper and water trucks. 

Erosion & Sediment

Controls in place to prevent erosion and sedimentation, such as silt fences and erosion control blankets.


Regular environmental inspections, which include monitoring the items above. 

Property Access

Metrolinx will notify property owners if any property access in required.

Construction Notice

We do our best to provide our neighbours with advance notice of construction work.

We will contact you in advance if we anticipate any impacts to transit users, pedestrians, traffic, residents or the public related to:

  • Lane closures
  • Removals on private property (trees, fences, sheds, etc.)
  • Night work
  • Track closures

Are there any plans for an over/underpass where the tracks cross Castlefield Ave just north of Eglinton?

What is the schedule to begin construction on Caledonia GO station and when is it expected to be completed / operational?

Traffic congestion will be a serious problem without an underpass. Would it be prudent to build an underpass at Ingram that extends to Caledonia to avoid severe disruption at Castlefield and improve traffic flow in this congested area?

What is the construction timeline for the pedestrian underpass under the Barrie line; that will connect St Helens Ave with Sterling Rd?

I own #1 & 3 Sheffield St. In the early stages of the 2 Nd track design that is right in the rear of our property, that there would be a sound barrier
wall for the train noise. I was in the zoom meeting when Metro links said that there would be sound a sound barrier wall built. I do not see it in your
area drawing. This was important to me as they stated there could be trains at 7 minit intervals. This was at the BIA information zoom meeting.
Where do we stand on the sound barrier Wall?
Thank You.
