Semi-Autonomous: The Archdiocese of Canada is a diocese of the Orthodox Church in America (OCA).

Its territory includes parishes, monasteries, and missions located in nine provinces and territories in Canada—Alberta, British Columbia, Manitoba, Newfoundland & Labrador, Nova Scotia, Ontario, Quebec, Saskatchewan, and Yukon.

The diocese was founded and incorporated by Saint Tikhon, Patriarch of Moscow and all Rus, in 1903.

On April 2, 2009, the Holy Synod of the Orthodox Church in America, elevated Higoumène Irénée (Rochon) to the rank of Archimandrite, and elected him to be Auxiliary Bishop for Archbishop Seraphim of Ottawa and Canada, with the title of Bishop of Québec City.

The deans coordinate activities in their area's parishes, and report to the diocesan bishop.
