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. In a Progressive model, the project features a collaborative approach between the project owner and the contracting partner. In the Spring of 2022, Metrolinx and Infrastructure Ontario (IO) executed an agreement with ONxpress Transportation Partners (ONxpress) to enter the Development Phase of the On-Corridor Works project—the largest project in Metrolinx’s GO Rail Expansion program.
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.
