Established in 1912, the Roman Catholic Diocese of Calgary stretches 110,000 square kilometres spread across southern Alberta. Comprised of over 450,000 Catholics, 70 parishes and 17 missions, the Diocese is led by Bishop William T. McGrattan. We have many offices that provide administration, pastoral care, and services that strengthen our Diocese. Our mission of “Feed my lambs. Feed my sheep.” drives everything we do to spread the Gospel of Christ to Southern Alberta.
