Ontario Archival Accessions Register (OAAR)

The Ontario Archival Accessions Register (OAAR) is an online register of accessions to archival institutions in Ontario. The registry has been developed in conjunction with the Provincial Acquisition Strategy to allow Ontario archives to share basic information on the new records that they have received in the previous year. OAAR is intended to capture brief details on newly acquired records at the point of acquisition, before processing has taken place.
