The Tunnelling Association of Canada (TAC) brings together Canadian, North American and International individuals and firms to promote and advance Canadian tunnelling and underground excavation technologies and to represent the interests of the tunnelling and underground excavation community in matters of technical and public concern.

Through association-sponsored meetings, course, workshops and conferences held across Canada, TAC encourages excellence and safety in the design, construction and maintenance of tunnels and underground excavations.

As the Canadian representative body of the International Tunnelling Association (ITA) the Tunnelling Association of Canada helps ensure Canadian tunnelling practitioners are connected to a world-wide network of experts keeping Canadian practice at the highest standards of international excellence.
