GO Expansion On-Corridor Works 

Toronto, Ontario

The GO Expansion is the largest transit project in Ontario’s history – transforming transit across the province. This innovative, fully integrated contract begins with a two-year collaborative development phase to finalize the scope, commercial structure, and pricing of various elements of the project, with certain construction and early works activities commencing during this phase.

Operations and maintenance are anticipated to commence upon completion of this period, and further information on the contract value and schedule will be disclosed following the development phase. The project is the culmination of the GO Expansion program and will electrify and transform the GO Rail network into a system that will deliver two-way, all-day service every 15 minutes or less across five core rail corridors in the Greater Golden Horseshoe Area.

Infrastructure Ontario & Metrolinx

Upon taking over operations and maintenance responsibilities, ONxpress will be responsible for providing expanded train service across the rail network, including major improvements to the existing timetable planning, operating train services including crewing, as well as maintenance of fleet, facilities, train control and electrification systems.

System-wide infrastructure upgrades will include adding 205 kilometres of new track, electrifying 687 kilometres of the rail network, significant enhancements to platforms and tracks at Union Station, building new maintenance and storage facilities, and installing train control and signaling systems to enable more frequent service.

The scope of work will also include upgrading and constructing new bridges, level crossings, grade separation structures, drainage systems and significant earthworks.

“Aecon is purpose-built with the multidisciplinary expertise, preeminent execution capabilities and sophisticated processes to build and operate projects of this magnitude and we look forward to working with Infrastructure Ontario, Metrolinx and our partners to deliver this unprecedented and sustainable project,”

Jean-Louis Servranckx, President and Chief Executive Officer, Aecon Group Inc.
