The Archives of the Roman Catholic Archdiocese of Toronto (ARCAT) collects, preserves and makes available for research the official records of the Archdiocese of Toronto and those ancillary records which reflect the work of the Church within the Archdiocese. ​​

​Under Canon Law, all dioceses are required to maintain an archives. The purpose of preserving records is twofold:

  • First, records need to be kept as evidence of business activity, in order to comply with regulatory and legislative requirements, and to support accountability.
  • Second, records are kept for historical and cultural purposes. The materials preserved by ARCAT serve as an illustration of the life of the Archdiocese. Twenty-first century Catholics are able to feel a connection to the Catholics who came before; the larger community is able to see how the Church helped to shape the Toronto they now know. Stories of yesterday can be a powerful tool for evangelization today.​
