Lead Office



10.00 Billion CAD

On April 14, 2022, ONxpress Transportation Partners, the consortium formed by Aecon, Deutsche Bahn, Alstom and FCC, reached commercial close on its contract to design, build, operate and maintain the GO Rail Expansion On Corridor Project, the largest project in Metrolinx’s GO Rail Expansion program, and are now implementing the development phase for the Project. Unprecedented in its scale and complexity, this multi-billion dollar capital program will transform the regional rail network with electrification, more frequent service, shorter journey times and a more modernized system for the Greater Toronto and Hamilton Region.

The GO Rail Expansion On-Corridor Project package is a single, innovative, fully-integrated contract to run more and better service for the regional GO rail system. ONxpress is responsible for designing, building, operating and maintaining all GO Rail infrastructure and trains for 25 years. This includes all works that facilitate train service, such as track, civil infrastructure, signalling, electrification infrastructure and electric vehicles, as well as the operations and maintenance of the GO rail network.

As the On-Corridor Project is a complex regional project with multiple external interfaces, stakeholders, utility and operational elements, it is being delivered as a Progressive DBOM (design-build-operate-maintain) model. In a progressive model, the project features a collaborative approach between the project owner and the contracting partner. Before the project’s contractual schedule and price can be finalized, the parties will enter a development phase – a multi-stage design process, whereby Metrolinx as project owner, and ONxpress as contracting partner, work closely together to finalize the scope, risk allocation and pricing of various elements of the project. The magnitude of On-Corridor Works requires a two-year development phase to progress the design and construction of any early works for the project.
