TAC assigns Canadian members to one of five national chapters (British Columbia, Alberta, Prairies, Ontario and Quebec/Maritimes) where members are invited to partake in activities and discussions to share knowledge alongside fellow professional colleagues and peers. Local chapters regularly hold seminars, field trips, and socials that typically are offered to active TAC members at preferred prices.
TAC chapters form or elect executive committees to plan and manage their own events. At the current time, the BC and Ontario chapters are the most active.
