Carhagouha
The historic site Carhagouha (near Lafontaine, Ontario) is the Huron/Wendat name for the site of the first Catholic Mass celebrated in Ontario, Canada on August 12, 1615 by Fr. Joseph Le Caron (member of the Recollets order) in the presence of French explorer, Samuel de Champlain, and the Wendat. Each year a Mass is celebrated to mark the anniversary.
