The Nipigon Bay Anglican Parish comprises St. Mary's Anglican Church (Nipigon, Ont.); St. Matthew's Anglican Church (Dorion, Ont.); and St. Peter's Anglican Church (Red Rock, Ont.). St. Mary's is the mother church of the current parish. St. Matthew's, Dorion is now a community museum and St. Peter's was closed and sold to the United Church of Canada. 
In 1872, the Rev. D. B. Douglas arrived as the first Anglican missionary in the Thunder Bay area. The Rev. E. F. Wilson directed the construction the first St. Mary's - Negwenenang on McIntyre Bay, Lake Nipigon in 1880 (this was later ordered abandoned and removed at the order of the Indian Agent). In 1881 the Rev. Robert Renison, father of the future Bishop of Moosonee arrived in the area. The Bishop Edward Sullivan visited the Lake Nipigon area in 1882 organizing services and games for local children. Also in 1882, monthly worship services commenced in the home of Mr. Flanagan, the local Hudson's Bay Company manager. At them time, his was the only permanent residence at what is now Nipigon, Ontario. Rev. Renison moved services for the area to the new Canadian Pacific Railway station's waiting room at Nipigon (also called Neepigon or Nepigon). In 1888, the local people raised $250 to construct what is now St. Mary's Anglican Church, Nipigon. Growth in resource extraction in the area led to population increases. In 1920 the diocese established St. Matthew's Anglican Church (Dorion, Ont.) and in 1948 St. Peter's Anglican/ United Church was built at Red Rock, Ontario at the mouth of the Nipigon River.
