GO Rail Expansion - Lakeshore West Corridor Infrastructure Improvements Project

Greater Toronto Area
Project Type:
DBF – Design Build Finance
Infrastructure Type:
Contract Value:
$443 million

About the Project

Infrastructure upgrades, such as in-corridor enabling works, station improvements, and underpass works will further help to accommodate increased capacity on the Lakeshore West line as part of the planned expansion of GO Transit rail service.

GO Rail Expansion will transform the transportation network in the Greater Toronto and Hamilton Area over the next decade. Metrolinx will transform the GO Transit rail network into a system that will deliver two-way, all-day service every 15 minutes over core segments of the GO Rail network. System-wide infrastructure upgrades will include: adding tracks, expanding stations, electrification of the rail network, new locomotives and train control systems to enable more frequent service.

Demonstrating Value 

  • The Lakeshore West Corridor Infrastructure Improvements project is being delivered using a DBF model. Key benefits of a DBF model include significant risk transfer to the private sector over the life of the project agreement, greater cost and schedule certainty and greater potential for design and construction efficiencies and innovation. 
  • Based on precedent project experience, a DBF procurement model typically has delivered a value for money savings in the range of 10% to 15% compared to undertaking the same projects using traditional delivery models.
