Our goals


The goal is to deliver 15-minute or better, all-day service on the core GO Transit lines – Lakeshore West, Kitchener, Barrie, Stouffville, and Lakeshore East lines – to transform the way this region will move and to make it easier for customers to get to where they need to go. As On-Corridor Works 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.


The GO Expansion On-Corridor Works 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, signaling, electrification infrastructure and electric vehicles, as well as the operations and maintenance of the GO Rail network.


ONxpress was evaluated and selected based on criteria identified in the Request for Proposals process that began in May 2019. Criteria included design and construction methodology, operations and maintenance approach, including train service planning, approach to managing the project, collaborative behaviours of key individuals of the teams and indicative pricing for the project. The On-Corridor Works assets will remain publicly owned by the Province of Ontario and managed by Metrolinx as part of its GO Rail regional program.
