Diocese of Saint John, New Brunswick

The Roman Catholic Diocese of Saint John, New Brunswick (Latin: Dioecesis Sancti Ioannis Canadensis) (erected 30 September 1842, as the Diocese of Saint John in America) is a suffragan of the Archdiocese of Moncton. It was renamed on 15 November 1924 to the Diocese of Saint John, New Brunswick. The Diocese had been a suffragan of the Archdiocese of Halifax–Yarmouth from 1852 to 1936, when it was transferred to the newly erected Archdiocese of Moncton. The Archdiocese of Moncton was established to reflect New Brunswick Catholic's population and linguistic diversity.^[1]
