Ontario Line Subway Project

Client: Metrolinx
Scope: 15.5 km Subway Expansion of over $10 Billion
Ontario Line Subway Project

Overview

In 2019, Comtech was selected by Metrolinx and Infrastructure Ontario (IO) to provide Technical Advisory Services for the Ontario Line Subway Project. This Project is a new RT line in the City of Toronto which is a combination of tunnelled and elevated sections of over 15.5 kilometres. This project includes 15 stations and potential links to the Go-Transit and TTC lines 1 and 2. The route runs from the Science Center Station, where it connects with the Eglinton Crosstown LRT line to Exhibition and Ontario Place. The current estimated time for project completion is the end of 2027.

The Ontario Line will improve transit coverage in the City by connecting communities and key destinations, increase access to economic opportunities for people in the region by better connecting them to jobs and support Transit-Oriented Development (TOD) across Toronto.
