ONxpress Civils Contractor General Partnership has executed alliance contracts with Metrolinx to advance the GO Expansion project in Ontario, one of the largest rail projects in Canada.

ONxpress is a 50/50 consortium between Canadian contractor Aecon and FCC Canada, the local arm of the Spanish infrastructure group FCC. The announcement, dated 7 October 2026, confirms the consortium's formal participation in the civil works phase of the programme.

The GO Expansion project targets the commuter rail network serving the Greater Toronto and Hamilton Area (GTHA). Metrolinx, the provincial transit agency, is the client and will oversee delivery.

What will the works deliver?

According to the announcement, the project will bring improvements to the alignment and quality of the local network's lines. The stated goal is a transport system with greater frequency, capacity and reliability.

For commuters, the intended outcome is improved access to and from downtown Toronto and Hamilton — the two anchors of the GTHA region.

The alliance contract model places ONxpress in a collaborative delivery structure with Metrolinx, sharing risk and decision-making across the execution phase rather than operating under a conventional fixed-price arrangement.

A flagship project for Canadian rail

Metrolinx and the Ontario government have framed GO Expansion as one of the country's most significant rail undertakings. The programme aims to transform what is largely a peak-hour commuter network into a more frequent, all-day service.

For FCC, the contract marks a further step in its North American expansion, pairing with Aecon, one of Canada's largest construction firms.

No specific value for the newly executed alliance contracts was disclosed in the announcement. Works are expected to progress under the alliance structure with Metrolinx in the coming years.
