Archdiocese of Regina
Catholic ecclesiastical territory in Canada
The Roman Catholic Archdiocese of Regina (Latin: Archidioecesis Reginatensis) is a Roman Catholic archdiocese comprising the southern part of the Canadian province of Saskatchewan, as far north as the 30th township, or about 51°30' lat. The metropolitan province includes the suffragan dioceses of Prince Albert and Saskatoon. The seat of the diocese is in the city of Regina.
The Diocese of Regina was established on March 4, 1910, with Olivier Elzéar Mathieu as its first bishop. Only five years later, on December 4, 1915, Pope Benedict XV raised the diocese to an archdiocese. Its current archbishop, Donald Bolen, and staff now serve nearly 124,000 parishioners living in 158 parishes and missions scattered over more than 155,000 square kilometres in southern Saskatchewan. The archdiocese includes 9 deaneries.
Construction on the diocese's Holy Rosary Cathedral in Regina extended from 1912 to 1917 and was dedicated to Our Lady of the Most Holy Rosary in November 1913. This extraordinary Romanesque building was built with an interior large enough to welcome parishioners and clergy from across southern Saskatchewan for special Masses, ordinations, funerals, weddings, and installations of archbishops.
In 1998, the former Diocese of Gravelbourg was merged with the archdiocese, with its former cathedral now designated Our Lady of Assumption Co-Cathedral.

Why this record matters
“Archdiocese of Regina” is worth following because a concise public description often conceals a longer documentary argument. Here, Archdiocese, Regina and Catholic provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Nov 10, 2025. The linked authority identifier is Q1365380. Authority coordinates are 50.445, -104.626. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1910, 1915, 1912 and 1917.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
