CENTRAL OFFICE (CO) is fully self-supporting through group and individual contributions. CO fulfills AA’s primary purpose of helping alcoholics to achieve sobriety by: 

-Sharing information for the good of AA;

-Selling AA Conference approved literature; and

-Selling other items that mark lengths of sobriety. 

CO also provides a place for Operating Committees to meet and store material, and provides a home for the Hamilton Archives Repository.

Hours are 10:00 A.M. to 4:00 P.M. during the weekdays September through June, and 10:00 A.M. to 1:00 p.m. in July and August. We are closed for provincial statutory holidays. Arrangements may also be made to make purchases outside of regular operating hours (i.e. evenings and weekends) at mutually convenient times by contacting us by email at This email address is being protected from spambots.

We will meet customers on the first floor to conduct transactions if contacted by phone at 905-522-8399. (The Helpline is 905-522-8392).

CO accepts payments including: cash, cheque, e-transfer, debit card, and credit card. There is a service fee of 0.265% for in-person credit card use.
