The diocese was established in 1859, and is the oldest in the Ecclesiastical Province, once extending over the entire civil province of British Columbia, hence the origin of its name. Its first bishop was George Hills. Notable parishes include Christ Church Cathedral and the Church of St. John the Divine, both in Victoria. The See is currently vacant, but the diocesan administrator is the Most Reverend Caleb Lawreance. The bishop is Logan McMenamie.
