World Tunnel Congress 2026 (WTC 2026)

About the event

The World Tunnel Congress 2026 (WTC 2026) is one of the most important global events dedicated to tunnelling and underground infrastructure. The congress will take place from May 15 to May 21, 2026, in Montréal, Canada, at the Palais des congrès de Montréal. Organized under the International Tunnelling and Underground Space Association (ITA) together with the Tunnelling Association of Canada, the event gathers professionals from around the world to exchange knowledge and discuss the latest developments in underground construction and engineering.

The theme of the 2026 congress is “Connecting Communities through Underground Infrastructure.” The event will focus on the role of tunnels and underground spaces in improving transport systems, urban development, and sustainable infrastructure. Participants will explore how underground engineering solutions can support growing cities while preserving surface space for environmental and social use.

WTC 2026 will include a comprehensive program featuring keynote presentations, technical sessions, workshops, and industry meetings. Experts will present research findings, engineering case studies, and innovative technologies related to tunnelling methods, underground construction, safety systems, digitalization, and infrastructure maintenance. The congress also hosts the ITA General Assembly and a large exhibition where companies present equipment, technologies, and services used in modern tunnelling projects.

The event is expected to attract thousands of professionals including engineers, contractors, researchers, infrastructure managers, and government representatives. In addition to the technical program, WTC 2026 offers networking opportunities, technical site visits, and social events that encourage international collaboration and knowledge exchange within the global tunnelling and underground infrastructure community.
