About St. Peter's Seminary

St. Peter's Seminary is a Roman Catholic educational institution located on Waterloo St in the Old North neighbourhood of London. Serving the Diocese of London and the broader Church in Canada and beyond, the seminary provides a spiritual and intellectual home for individuals seeking deeper formation. It is recognized as the oldest English-speaking diocesan seminary still in operation in the country, having served the Church since 1912. The institution offers a variety of academic and spiritual programs for men preparing for the ministerial priesthood, as well as for those seeking a life of service in the permanent diaconate or lay ministry. For students seeking graduate theological degrees, the seminary provides the Master of Divinity, Master of Divinity - Advanced, and Master of Theological Studies as an accredited member of the Association of Theological Schools (A.T.S.). Through an academic affiliation with King’s University College at Western University, it also offers undergraduate degrees in philosophy. Additionally, the St. Peter’s Institute for Ongoing Formation provides continuing education for clergy, permanent diaconate candidates, parish staff, and lay ecclesial ministers to strengthen pastoral skills and spiritual growth. The seminary describes its mission as forming hearts and shaping servants through an integrated program of spiritual, human, intellectual, and pastoral formation. It emphasizes a tradition-rooted approach that remains responsive to modern needs, fostering leaders grounded in faith and compassion. The campus features the Chapel of St. Thomas Aquinas, which contains 84 hand-carved wooden angels, and the A.P. Mahoney Library, a known resource for theological research. While the seminary primarily admits candidates from dioceses and religious communities across Canada for priestly formation, it also welcomes men and women of both religious and lay backgrounds for its various theology and philosophy programs.
