The Archdiocese of Ottawa–Cornwall (Latin: Archidioecesis Ottaviensis–Cornubiensis, French: L'Archidiocèse d'Ottawa-Cornwall) is a Catholic archdiocese that includes part of the Province of Ontario and includes the suffragan dioceses of Hearst, Pembroke, and Timmins. On 6 May 2020, Pope Francis amalgamated the Archdiocese of Ottawa and the Diocese of Alexandria-Cornwall to create the Archdiocese of Ottawa–Cornwall.
The Diocese of Bytown was erected on 25 June 1847. Its name was changed to the Diocese of Ottawa on 14 June 1860. It was elevated to archdiocese status on 8 June 1886. As of 2004, the archdiocese contained 111 parishes, 177 active diocesan priests, 102 religious priests, and 400,000 Catholics. It also has 848 Women Religious, 147 Religious Brothers, and 60 permanent deacons.
