Most Croatian Canadians are Roman Catholic who follow the Latin Rite of their ancestors in Croatia and Bosnia and Herzegovina. A very small minority of Croatians are Byzantine Rite Roman Catholics. There is also a community of Croats who follow Islam, the descendants of those who converted after the 16th century, after the conquest of much of Croatia by the Ottomans.
