Welcome to the 33 Service Battalion Association!

33 Service Battalion is a reserve Canadian Army Combat Service Support unit that provides logistics and maintenance support services. The Battalion has served Canada for more than 50 years and has generated part-time and full-time soldiers for domestic and expeditionary military operations. Our Association was founded to support the outstanding soldiers who are serving or have served with 33 Service Battalion, and we are comprised of serving and past members. Formerly known as the Ottawa Service Battalion Association (OSBA), our name changed in 2022 to be inclusive of our detachments in North Bay and Sault Ste Marie, in addition to Ottawa.
