Metrolinx's $75B GO Expansion: Where Trade Packages Sit

Metrolinx's $75B GO Expansion: Where Trade Packages Sit

Metrolinx’s $75 billion GO regional expansion covers 600 kilometers of rail, and much of it is being built overnight on live corridors. Daily Commercial News covered a presentation by Metrolinx head sponsor for GO Expansion Jake Schabas at the Transport Futures Ontario Intercity Travel Summit in Toronto, published October 20, 2026. Schabas laid out five “missions” and a build sequence that shows where trade scopes will open up over the next decade.

Background

Schabas said the program aims to deliver more frequent, two-way, all-day service across much of the GO network. It includes electrification and faster trains on key corridors, phased in over the next decade. He described the work as spread over 600 kilometers, with bridge demolition in Oshawa to widen a corridor roughly 60 kilometers from downtown happening at the same time as work in Georgetown and Burlington.

The five missions are Lakeshore East, Lakeshore West, Kitchener and Union Pearson Express, Stouffville, and Barrie. Schabas said many corridors, including Barrie, Kitchener and Stouffville, still have long stretches of single track that limit two-way service. Metrolinx has spent 10 to 15 years widening corridors and building platforms and bridges for additional tracks.

The sequence from here, per Schabas: signalling modernization using European Train Control System Level 2, then level crossings (which he called an “absolute priority” for safety), then electrification and the new fleet. The source names ONxpress Transportation Partners as a major constructor. It is a consortium led by Aecon Concessions, Alstom, FCC Construccion and Deutsche Bahn, awarded the On-Corridor Works project in 2022.

Analysis

The package breakdown. Using the mission lists Schabas presented, the work sorts into clear scope families:

• Track and corridor civil: This is the most active category now. Under construction are new track and civils on the Bowmanville Extension, third track reinstatement from Union Station Rail Corridor (USRC) to Scarborough Junction, a fourth track from Lansdowne to Dupont, and second tracks at Highland to Underwood and Concord to Teston.
• Stations and platforms: Active work includes a second platform at King City, platforms at Mount Joy, Maple, Aurora and Downsview Park, and accessibility upgrades at Long Branch.
• Grade separations: Burloak Drive and Finch Avenue are under construction. Morningside Avenue, Galloway Road, Poplar Road and Silver Junction are in design.
• Signaling: Upgraded signaling is in design on all five missions.
• Electrification: This is also in design on all five missions, from USRC to Burlington, Oshawa, Pearson and Allandale, and from Scarborough Junction to Old Elm.

Our inference: because electrification and the new fleet come after signalling and level crossings, the biggest electrical and systems scopes are the furthest out. Track, civil and grade separation work is where most trades can find work today. Grade separation is a useful comparison. Four of the six named projects are still in design.

The Grimsby example. Daily Commercial News ran a related item on October 15, 2026 headlined “Contract awarded for Grimsby GO Station work,” saying the Ontario government awarded a contract to a Kenaidan Murphy entity. The source excerpt does not include the contract value, scope or subcontract packages. Grimsby also does not appear in any of the five mission lists Schabas presented. Our inference: station awards like this may run as separate procurements alongside the mission work, but the source does not say. Confirm details with the awarded contractor or Metrolinx before planning around it.

What the source does not say. There are no Metrolinx procurement dates, bid windows or package values in this article. It also does not mention utility relocations as a scope, and it does not say which mission projects sit inside the ONxpress On-Corridor Works contract. Any bid calendar has to come from Metrolinx’s own published schedule, not from this coverage.

Night work is the default. Schabas said most of the work happens “when everyone’s asleep,” because GO runs service today. Our inference: that favors firms that can staff overnight possession windows and sit comfortably with rail protection requirements. A low bid alone will not win much work.

What It Means for Subcontractors

• Civil and track crews: Active scopes include Bowmanville Extension track and civils, third track reinstatement from USRC to Scarborough Junction, and the fourth track from Lansdowne to Dupont. Target the contractors holding those packages now. The source names ONxpress (Aecon Concessions, Alstom, FCC Construccion, Deutsche Bahn) for On-Corridor Works, awarded in 2022, though it does not list which projects that covers.
• Bridge and grade separation trades (demolition, concrete, structural steel): Burloak Drive and Finch Avenue are under construction. Morningside Avenue, Galloway Road, Poplar Road and Silver Junction are in design, so those are the next structure packages to line up.
• Station and accessibility work: Under construction items include King City, Mount Joy, Maple, Aurora, Downsview Park and Long Branch. Grimsby GO Station work was awarded October 15, 2026. Contact the awarded contractor for subcontract scopes, since the source gives no package breakdown.
• Electrical, E&I and signalling: Upgraded signaling and electrification are in design on all five missions. Schabas put electrification and the new fleet after signaling and level crossings.
