Who We Are The ONxpress Civils Contractor General Partnership, a partnership between FCC Canada Limited and Aecon Infrastructure Management Inc., is a multidisciplinary Civils Joint Venture (CJV) team with global expertise in delivering innovative solutions for both railway and civil construction projects. Working under Alliance agreements with Metrolinx, the team is helping to modernize railway construction across the GO Transit network.

An Alliance framework, which is relatively new in Canada, is a collaborative partnership between the owner and contractor, who work together with a best-for-project mindset. By streamlining decision making, the Alliance helps ensure that high-quality work is delivered, certified, and transferred in a progressive, transparent, and risk-managed manner.

The Alliance operates with a core focus on safety, efficiency, and sustainability, while fostering strong relationships with stakeholders and rights-holders and contributing positively to local communities as a good neighbour. Through this collaborative approach, the Alliance is helping drive the modernization of key sections of the rail network as part of the GO Expansion Program.
