Infrastructure Ontario (IO) and Metrolinx have issued a Request for Proposals (RFP) to three shortlisted teams to design, build, and finance the Lakeshore West Infrastructure Improvements project. The infrastructure upgrades are required to accommodate the planned expansion of GO Transit rail service on the Lakeshore West line.

“Today’s announcement launches us toward an even better experience for our customers on the Lakeshore West line,” said Phil Verster, president and CEO of Metrolinx. “We’re very excited to get going on these projects, as they will bring better connections to our stations and the surrounding community, more frequent service and faster, electric trains.“

The shortlisted teams were selected based on criteria identified in the Request for Qualifications process that began in December 2017. Criteria included their design and construction capability, experience, qualified personnel and financial capacity to deliver a project of this size and scope.

These teams are invited to respond to the RFP and will begin preparing proposals that detail how they will design, build and finance the project. Once submissions are received, IO and Metrolinx will evaluate the proposals, select a preferred proponent, and then negotiate a final contract.

Work on the Lakeshore West Line is part of a larger, system-wide plan to improve overall GO Transit service, including the delivery of GO Regional Express Rail by 2024-25.

The project is being delivered as a Design Build Finance (DBF) contract using Infrastructure Ontario’s Alternative Financing and Procurement (AFP) model.
