About Us

The Archives Association of Ontario (AAO) was established in 1993 as a result of the amalgamation of the Ontario Association of Archivists and the Ontario Council of Archives. It is a network of archives and archivists providing programs, education, advocacy and shared knowledge, consisting of approximately 300 members

The AAO represents archival institutions, those working in archives, as well as volunteers, patrons, and supporters of archives. It promotes archives as vital to the fair, transparent, and equitable operations of the Canadian and Ontario governments and society as a whole. 

Please review the AAO's constitution and explore the website to connect and learn about the work of archivists in preserving Ontario and its citizens' history and culture. 

The AAO is grateful for the support of the people of Ontario through the Archives of Ontario, Ministry of Government Services.

The AAO also receives support from the Ministry of Tourism, Culture and Sport through the Provincial Heritage Organization Operating Grant.
