One of the interesting things I learnt through Fr. Dennis Kolinski of the Canons Regular of St. John Cantius, was that the Canons Regular do operate in more than just their famed parish church of St. John Cantius itself.
The Canons now also have an additional parish apostolate, that of St. Peter's Parish in Volo, Illinois.
While on their website, you might also want to look at the beautiful retreat chapel of the Canons Regular, St. Anne's Chapel in Lawton, Michigan. The Eastern feel to the building is no mistake, having been constructed in Poland and then re-constructed in the United States for the Canons Regular.
