Metrolinx launches Line 6 Finch West Light Rail Transit

Metrolinx recently opened the Line 6 Finch West Light Rail Transit (LRT) line, a transformative addition to the city’s transit network. Toronto’s first new transit line in 23 years spans nearly 11 kilometers (6.8 miles) with 18 new stops from Humber College to Finch West Station and features new, modern light rail vehicles (LRVs).  

The new LRT line significantly improves connectivity for residents and commuters, easing congestion on major routes and providing thousands of daily riders with safe, reliable, and environmentally sustainable transportation.

Our overall role on the project involved comprehensive quality assurance and engineering services in the delivery of the LRVs, which included:

• Technical oversight: We led the review of design submissions and engineering drawings for the LRVs, ensuring compliance with stringent quality standards for performance and safety.
• Quality assurance: Our team provided on-site quality assurance at the LRV supplier’s assembly plant, conducted factory inspections, and witnessed critical testing phases, including dynamic traction and braking validation.
• System integration: We supported system integration activities, facilitating coordination between multiple project partners and end-user departments. 

Reflecting on the project, Brandon Johnson, project manager for Mott MacDonald, said “Delivering the Finch West LRT has been a true team effort, requiring close collaboration with Metrolinx, the vehicle supplier Alstom, and our partners. Our focus on quality assurance and technical excellence means Toronto’s new light rail vehicles are ready to serve the community for decades to come. We’re proud to have played a part in bringing this vital transit link to life.”

“The opening of Line 6 Finch West is a major advancement for Toronto’s transit future and demonstrates what can be achieved when partners come together with a shared vision of delivering innovative, resilient, and sustainable solutions,” said David Wright, transit and urban mobility market leader at Mott MacDonald. “We are honored to have contributed to this milestone and cannot wait to see the lasting benefits for the city and its communities.”
