TMAC currently has four regional chapters: British Columbia; Alberta & Northwest Territories; Ontario; and Atlantic.

Chapters often organize their own social activities and/or professional development sessions. Some maintain social media accounts as well. They each annually elect a board of directors and meet as well during the annual conference.

They provide TMAC members with additional opportunities to network throughout the year. Chapter chairs (and/or boards) also serve as the first point of contact for TMAC members who may have a compliment, complaint or issue to share.

TMAC members who do not live within the geographic borders of a chapter can contact the TMAC President, or any member of the national board, if they have concerns.

Generally speaking, TMAC chapter events are open to all TMAC members, though it is advisable to confirm beforehand; many events have RSVP deadlines or associated fees.
