 Bishop Gains and his parish later joined the IACCS as did Bishop Michael Fedechko, formerly Bishop Primus of the Reformed Episcopal Church of Canada, along with his parish in New Liskeard, Ontario.The IACCS describes itself as conservative, having retained the use of the historic "Book of Common Prayer", the "Book of Common Praise 1938", and "Anglican Chant for the Psalms and Canticles".It requires that all clergy subscribe to the Thirty-nine Articles of Religion.
