In partnership with Metrolinx, ACCIONA is playing a key role in the design and construction of the Eglinton Crosstown West Extension (ECWE), a 9.2‑kilometre westward addition to Toronto’s Line 5 light rail transit network. This major infrastructure project includes seven new stations and installation of rail and systems under a progressive design‑build model. Beyond its technical scope, the ECWE project represents a significant investment in sustainable urban mobility, expected to reduce greenhouse gas emissions by up to 5,800 tonnes annually and eliminate over 6.5 million vehicle trips each year when combined with the full Line
5. This is a unique opportunity to join a dynamic, multidisciplinary team on a complex, high‑value project that supports long‑term regional growth and environmental sustainability.
