Per their website:
The Traditional Anglican Communion (TAC) is a worldwide association of orthodox Anglican churches, working to maintain the catholic faith and resist the secularization of the Church. Our member churches comprise more than 400,000 members on 6 continents.We strive to faithfully carry the catholic message of the Gospel of Jesus Christ to a world which desperately needs it, and to preserve the "faith once delivered to the saints" in its Anglican form as the true and valid expression of that message.
I couldn't tell if they were part of Canterbury or not. Can you?
