Mace, Comtech and SYSTRA awarded Delivery Partner contract for largest transit infrastructure program in Canadian history

March 01, 2022

Mace, Comtech and SYSTRA, working as the MCS consortium, are pleased to announce it has been awarded the contract of Program Delivery Partner to support Metrolinx’s GO Expansion program. MCS will establish a program level management regime to integrate all aspects of the GO Expansion program through the development, implementation and continuous improvement of program-wide systems, processes and procedures in order to support ‘Best for Program’ decision making, subject to Metrolinx’s governance, policies and procedures.


MCS will be integrated as delivery partners with Metrolinx to manage this complex program of works, which includes new stations, electrification of existing lines, installing new rail lines, upgrading existing stations, signalling, and more. The Program Delivery model brings skilled external partners into the Metrolinx team, to collaborate in managing integration and delivery of major projects through all phases.

The 10-year rail infrastructure program, GO Expansion, is Metrolinx's largest and most ambitious endeavour to date and aims to expand the GO Transit rail service. With a long-term vision of providing two-way, all-day service, every 15 minutes or less on core segments of its rail network, Metrolinx will provide increased connections between communities.


As an infrastructure program, GO Expansion will support the growing regional economy through job creation and improved connectivity, unlocking investment and urban development in the province of Ontario. The combination of cleaner, electric trains and more people using metro-style transit will also significantly improve air quality in the Greater Toronto and Hamilton Area.


Together, the three firms will draw on their individual strengths for the benefit of the program. Mace will leverage British expertise from the mobilization of large integrated teams on the HS2 program at Euston Station in London as well as Birmingham New Street Station, and from its successful role as a delivery partner for the London 2012 Olympic Games.


In equal measure, Metrolinx will benefit from Comtech’s experience delivering multiple mandates within Metrolinx’s capital projects portfolio and expertise in program delivery and information system management, along with French engineering firm SYSTRA’s extensive international track record in rail construction, operations, and maintenance.
