History

A suffragan in the ecclesiastical province of the metropolitan Archdiocese of Toronto, the Diocese of London (Latin: Diœcesis Londonensis) is a Latin Church diocese of the Catholic Church in Canada. Its present episcopal see, St. Peter's Cathedral in London, Ontario, rose between 1880 and 1885 in a French Gothic Revival style, and Pope John XXIII raised it to the status of a minor basilica in December, 1961.

What is kept by invitation

The record above is published because it is public: what this see is, when it was erected, who holds its chair, and where it stands among its neighbours.

The working record is not. The chancery's address, telephone and email, the clergy of the see, and the hours of Mass, confession and adoration in the parishes within it are kept for members, and a person reads every request.
