What Tunnelling Association of Canada does
The Tunnelling Association of Canada (TAC) is a professional membership association founded in 1984 and headquartered in Toronto, Ontario. As the Canadian representative body of the International Tunnelling Association (ITA), TAC brings together Canadian, North American, and international individuals and firms to promote and advance tunnelling and underground excavation technologies. It serves three primary member segments: tunnelling professionals (contractors, engineers, researchers), students and early-career professionals, and corporate member firms (over 70 organizations including AECOM, Hatch, Jacobs, AtkinsRealis, and Arup). Five regional chapters (British Columbia, Alberta, Manitoba and Prairies, Ontario, Quebec and Maritimes) extend TAC's footprint across Canada.
TAC's core products include the Canadian Tunnelling Magazine (published twice yearly in partnership with Tunnelling Journal), a free GIS-based Tunnel Dashboard cataloguing Canadian tunnelling projects, and a pilot Mentorship Program launched July 2025 in partnership with PDL Mentoring. Supporting offerings include the Tunnelling 101 Learning Series (webinars on TBM selection, risk management, and other technical topics), conference proceedings archives dating to 1984, annual achievement awards, graduate and undergraduate scholarships, the Young Professional's Think Deep Program, and a careers portal integrated with the Engineering Institute of Canada. The association hosts the annual TAC Conference and is the host organization for the World Tunnel Congress 2026 (WTC 2026) in Montreal, expected to draw 2,800 delegates from 66 countries and 231 exhibitors.
TAC operates a subscription-based revenue model: $700/year corporate memberships, $100/year individual memberships, $30/year retired memberships, and $12.50/year student memberships (annual cycle January–December). Supplementary revenue is generated through magazine advertising, conference registrations, exhibition and sponsorship fees, and a $50-per-corporate-member allocation to a student initiative fund. Distribution occurs via direct website enrollment, the five regional chapters, and annual conferences. The association maintains an active presence on LinkedIn, Instagram, Facebook, and YouTube.
