By far the largest group of Western Orthodox parishes is represented by the [[Western Rite Vicariate]] of the [[Antiochian Orthodox Christian Archdiocese of North America]]. Other Antiochian Western Rite parishes exist in the [[Antiochian Orthodox Archdiocese of Australia and New Zealand]].
The [[Russian Orthodox Church Outside Russia]] (ROCOR) also has a small number of Western Rite parishes in addition to three monasteries: one located in Canada, one in Tasmania, and one in Florida. Missions and parishes of the ROCOR Western Rite use either the Rite of St. Gregory in one of varying uses (Sarum, Christminster, Mount Royal, or Overbeck), the Gallican Rite, or "The English Liturgy," an English Use service based upon the Sarum Use but which adapts a few elements of the 1549 ''Book of Common Prayer''. Christminster Monastery in Hamilton, Ontario, Canada, is a Western Orthodox Benedictine monastery, which celebrates the Liturgy of St. Gregory. St. Petroc Monastery in Hobart, Tasmania, Australia, celebrates the [[Sarum Use]]. St. Petroc has a number of dependencies that follow its liturgical usage, as found in the ''Saint Colman Prayer Book''.
Dom Augustine (Whitfield), the [[abbot]] of the Monastery of Mount Royal from 1963 until retirement, once remarked to St. [[John Maximovitch]] that it was difficult to promote Western Rite Orthodoxy, whereupon the saint replied: "Never, never, never let anyone tell you that, in order to be Orthodox, you must also be eastern. The West was Orthodox for a thousand years, and her venerable liturgy is far older than any of her heresies." [http://www.christminster.org/history.htm]
