Those who attend the Workshop for Laity in the Extraordinary Form (1962 Missale Romanum) will be instructed by members of the Canons Regular of St. John Cantius, Chicago. The priests of the Canons Regular will also provide lectures to the registrants about the history, spirituality and importance of the Extraordinary Form in the Church today.

The Canons Regular of St. John Cantius was founded in 1998 by Fr. C. Frank Phillips, C.R. as a Roman Catholic religious community of men dedicated to a 'Restoration of the Sacred' in the context of parish ministry. Its mission is to help Catholics rediscover a profound sense of the sacred through solemn liturgies, devotions, sacred art, sacred music, as well as instruction in Church heritage, catechetics, and Catholic culture. This mission is reflected in the community's motto: Instaurare Sacra (Restoration of the Sacred).

The purpose of the Canons Regular of St. John Cantius is the formation of a Roman Catholic men's diocesan institute, which shall form and train men to be priests and brothers. On December 23, 1999, the Feast of St. John Cantius, Francis Cardinal George, O.M.I., Archbishop of Chicago, issued a "Decree approving the statutes and erecting the Society of St. John Cantius as a public diocesan association of the Christian faithful with juridic personality." On January 31, 2003, he gave his approval to the recently completed Spiritual Directory and Book of Customs as the local provisionary rule for the Canons Regular of St. John Cantius, the next step toward approval of constitutions as a diocesan institute of religious life.
