Ontario Line

A new 15.6-km subway line in Toronto that will run from Exhibition Place, through downtown, all the way to the Ontario Science Centre.

Trains and technology

The Ontario Line will be able to deliver faster, more frequent service by using modern technology that has been adopted by subway systems around the world. The line will feature fully automated trains with modern signalling like the ones used in Vancouver, London, Paris and Singapore. We will be able to cycle these through the system faster, meaning we can run up to 40 trips an hour with as little as 90 seconds in between trains.  

In November 2022, the Rolling Stock, Systems, Operations and Maintenance (RSSOM) contract was awarded to the Connect 6ix team. The RSSOM contract includes designing and supplying the trains as well as designing and building the maintenance and storage facility and the communications and train control systems, all of which Connect 6ix will operate and maintain over a 30-year term.   

Benefits of modern technology

The Ontario Line trains will be designed and built by Hitachi Rail and feature the latest technology, including: 

  • onboard Wi-Fi;  
  • digital passenger information screens;  
  • charging points;  
  • dedicated spaces for bicycles;  
  • double wheelchair areas;  
  • continuous, connected train cars;  
  • heating and cooling throughout;  
  • doors that will open in sync with platform edge doors;  
  • regenerative braking.  


Conceptual images from the RSSOM contract award show some of the station and train technologies that will be incorporated into the Ontario Line:
