Established, in 1973, the Ontario Association of Library Technicians / Association des bibliotechniciens de l'Ontario (OALT/ABO) is a professional, non-profit organization of Library and Information Technician graduates, students, associate and institutional members.

Technicians belong to one or more of the four established Chapters:

• Halton-Peel Chapter
• Ottawa Chapter
• School Chapter
• Toronto Chapter

Book Club Chapter is a virtual chapter available to all members through the members only area of the OALT/ABO website.

Each OALT/ABO Chapter is autonomous and elects its own executive. The Association Executive is elected at the Associations annual conference. The Executive meets several times a year and it is at these meetings, that association policies are established and financial control maintained.
