After dialoguing with the Church of Constantinople the UGOCC was received into its jurisdiction as the Ukrainian Orthodox Church of Canada in 1990, bringing it into the full communion of the canonical Orthodox Church. (Several years later its sister church, the Ukrainian Orthodox Church of the Diaspora, also joined the Patriarchate of Constantinople.) The decree of Ecumenical Patriarch Demetrius (Papadopoulos) uniting the UOCC with the Church of Constantinople recognized the Church’s internal autonomy under its metropolitan, justifying the reception of the UOCC into the Patriarchate’s jurisdiction on the basis of the historic jurisdiction of the Church of Constantinople in Ukraine.
