Trillium Guideway Partners

Trillium Guideway Partners (TGP) is at the forefront of delivering the Ontario Line Elevated Guideway and Stations contract, selected by Infrastructure Ontario and Metrolinx. The team has signed a Development and Master Construction Agreement (DMCA) with Metrolinx, under a progressive design-build contract.

The Trillium Guideway Partners team includes: • Applicant Leads: Acciona Infrastructure Canada Inc. and Amico Major Projects Inc. • Design Team: WSP Canada Inc. • Construction Team: Acciona Infrastructure Canada Inc. and Amico Major Projects Inc

Under the Development and Master Construction Agreements (DMCA), we embrace a progressive design-build model, facilitating collaboration between Metrolinx and TGP to finalize scope, risk allocation, and pricing.

With a multi-stage development approach, we ensure attention to detail, enabling early works construction while fostering a collaborative environment. Our scope of work includes three kilometres of an elevated guideway (bridge structures); five elevated stations (Riverside-Leslieville, Gerrard, Thorncliffe Park, Flemingdon Park, Science Centre), one emergency exit building, interface with the operations and maintenance storage facility as well as with the Eglinton Crosstown LRT Line 5 and sections of existing Metrolinx-owned rail corridor where Ontario Line trains will operate.

At TGP, we recognize the importance of public-private partnerships (P3) and progressive design-build approaches in delivering transformative infrastructure projects like the Ontario Line. We are committed to meeting the challenges of this dynamic project with efficiency, innovation, and dedication to the communities we serve.
