The Anglican Diocese of Quebec was founded by Letters Patent in 1793 and is a part of the Ecclesiastical Province of Canada of the Anglican Church of Canada, in turn a province of the Anglican Communion. The diocese comprises the 720,000 square kilometres and took it present shape in 1850 with the carving off of what is now the Diocese of Montreal and includes a territory of west to east from Magog to the Gaspe and the Magdalen Islands, south to north from the United States border to Kawawachikamach and the communities of the Lower North Shore.
The diocesan office is located in Quebec City, as is the Holy Trinity Anglican Cathedral. The diocese maintains approximately 7,200 on its parish rolls in 52 parishes, averaging one member per 100 km². The Rt. Rev. Dennis Drainville was elected Coadjutor Bishop of Quebec on 12 October 2007 and was installed as the 12th Bishop of Quebec on 31 May 2009.
With both the dioceses of Quebec and Montreal having less than 10,000 members and decreasing numbers, discussions are underway for the eventual merger of the two dioceses, beginning with an exploration of opportunities for combined administration.
