Our History

33 Service Battalion has served Canada for almost 50 years and has generated part-time and full time soldiers for domestic and expeditionary operations.

33 Service Battalion is a descendant of the Ottawa Service Battalion which arose from the amalgamation of several service support units in Ottawa in 1965. The Ottawa Service Battalion was first composed of personnel from 130 Transport Company, 3 Ordnance Company, 28 Technical Squadron, 13 Personnel Depot, 113 Manning Depot, 10 Medical Company and 54 Dental Unit. These units were disbanded to form the Battalion which had a single transport unit and a training wing. This was later expanded into a transport company, supply company, maintenance company, Headquarters, MIR and MP detachment.
