Archeion is Ontario's Archival Information Network, an online research tool providing access to descriptions of archival records held by members of the Archives Association of Ontario (AAO). The records themselves are preserved and made accessible via the individual archives. Archeion is a member-supported service provided by the AAO.

The AAO represents archives and archivists who are committed to promoting the preservation and use of the documentary heritage of Ontario. It provides educational and outreach programs for archivists across the province and promotes professional standards, procedures and practices in archival repositories.

Archival institutions which are members of the AAO are eligible to have descriptions of their archives included in Archeion.


Archeion uses the AtoM open source archival description software, developed and hosted by Artefactual Systems.
