As the British Empire expanded, British colonists and colonial administrators took the established church doctrines and practices together with ordained ministry and formed overseas branches of the Church of England. As they developed or, beginning with the United States of America, became sovereign or independent states, many of their churches became separate organisationally but remained linked to the Church of England through the Anglican Communion. In the provinces that made up Canada, the Church operated as the "Church of England in Canada" until 1955 when it became the Anglican Church of Canada.
