At the request of the Bishops of Canada and in view of current pastoral needs, major changes have been approved for the boundaries of dioceses situated in three provinces.

The Holy See has recently published Decrees modifying the boundaries of seven Dioceses and suppressing an eighth, the Diocese of Labrador City – Schefferville. The other Dioceses concerned are Amos, Baie-Comeau, Chicoutimi, Joliette and Trois-Rivières, all in the Province of Quebec; St. George’s, in Newfoundland; and Moosonee, in Ontario. The changes affect a total of 30 parishes and missions.

Delegates of the Holy See will witness the official proclamation of the Decrees and assist the local diocesan Churches in this reorganization. The delegates are Most Reverend Maurice Couture, S.V., Archbishop emeritus of Quebec City; Jean-Guy Couture, Bishop emeritus of Chicoutimi; Jude Saint-Antoine, Auxiliary Bishop emeritus of Montreal; and Martin Currie, Bishop of Grand Falls.


The Diocese of Labrador City – Schefferville always encompassed territory in what is now the Province of Newfoundland and Labrador as well as in the Province of Quebec. This recent reorganization has resulted in the formation of a new diocese, the Diocese of Corner Brook and Labrador. The new Diocese will comprise all parishes and missions in the present Diocese of St. George’s on the Island of Newfoundland in addition to those in the territory of Labrador, until now part of the Diocese of Labrador City – Schefferville. Those parishes and missions in the Province of Quebec which until now have been in the Diocese of Labrador City – Schefferville will be transferred either to the Diocese of Amos or to the Diocese of Baie-Comeau, depending on their geographic area.

The episcopal see of the new diocese will be in the City of Corner Brook, and the present Cathedral of the Most Holy Redeemer and the Immaculate Conception will remain the cathedral church. What has until now been the Cathedral of Our Lady of Perpetual Help in Labrador City has been designated a Minor Basilica by the Holy See, thus becoming the Basilica of Our Lady of Perpetual Help. Most Reverend Douglas Crosby, O.M.I., who for some years has been Bishop of Labrador City – Schefferville as well as serving as the Bishop of St. George’s, becomes the first Bishop of the new Diocese of Corner Brook and Labrador.

Changes in Quebec

With the change to its boundaries, the territory of the Diocese of Amos has grown considerably. The Diocese now includes the Quebec region of Nunavik that used to be part of the Diocese of Labrador City – Schefferville. As well, the diocese has been given responsibility for those communities in the Province of Quebec that until now have been part of the Diocese of Moosonee. Until this change, the Diocese of Moosonee has had a vast territory that encompassed parts of both Ontario and Quebec. With this adjustment of boundaries, only the parishes and missions within the Province of Ontario will form the Diocese of Moosonee.

One parish and two missions that have been within the Diocese of Amos will now form part of other diocesan territories. The Parish of Parent now becomes part of the Diocese of Trois-Rivières, the Opitciwan Mission will now belong to the Diocese of Chicoutimi, and the Manawan Mission will be joined to the Diocese of Joliette.

The lower North Shore of the Saint Lawrence River (the “Basse-Côte-Nord”) as well as the Schefferville areas of the former Diocese of Labrador City – Schefferville will now form part of the Diocese of Baie-Comeau.

The Decrees to the changes in diocesan territories will be implemented over the coming weeks, according to the decision of the Diocesan Bishop and the delegates of the Holy See. It has already been announced that the Decree changing the boundaries of the Diocese of Baie-Comeau will take effect during a Eucharistic celebration at which the Most Reverend Pierre Morissette, Bishop of Baie-Comeau, will preside in the parish church of Notre-Dame de Lourdes-de-Blanc-Sablon on Sunday, 2 September.
