AECON PARTNERSHIP REACHES FINANCIAL CLOSE ON THE PORT OF MONTREAL EXPANSION IN-WATER WORKS PROJECT IN CONTRECOEUR

Contrecoeur Terminal Constructors General Partnership, comprising Aecon Group Inc. (40 per cent) and Pomerleau (60 per cent), has completed the collaborative development phase and reached financial close on a design-build contract with the Montreal Port Authority for the Port of Montreal expansion in-water works project in Contrecoeur, Que. Finalized under a progressive design-build approach, the contract is valued at $609-million and Aecon's share of the contract will be added to its construction segment backlog in the fourth quarter of 2025.

The scope of work includes preparatory work, dredging, the construction of dock infrastructure, quay walls, return walls and auxiliary activities. Preparatory work will now commence, with construction expected to begin in 2026 and anticipated to be complete in 2030.

"Aecon is proud to be playing a key role in delivering the Port of Montreal expansion -- a major project that is leading the way in building a stronger economy," said Jean-Louis Servranckx, president and chief executive officer, Aecon Group. "Reaching financial close on the in-water works contract demonstrates the successful collaboration achieved during the development phase, and we look forward to working with the Montreal Port Authority and our partner to safely deliver this critical project."

"Aecon is at the forefront of building complex civil infrastructure, and we are pleased to advance to the construction phase of this nation-building project that will support economic growth and international trade by providing increased terminal capacity," said Thomas Clochard, executive vice-president and chief operating officer, Aecon Group.

The Contrecoeur terminal completes the largest container port in Eastern Canada and solidifies the Port of Montreal's status as a diversified transshipment centre served by some of the world's largest shipping companies. The terminal will connect to major rail and highway networks -- meeting the needs of Canadian importers and exporters.

Further information about the project is available on the Montreal Port Authority website.
