He organised a new Saint Theodore the Studite monastery in Kolodiivka, Ternopil Oblast, Ukraine, in 1994, and was elected by the Synod of Bishops of the Ukrainian Church as exarch of the archiepiscopal exarchy of Kyiv and Vyshhorod in 1995, confirmed by the Pope the following year (February 1996) by nominating to the titular see of Nisa di Licia.

[7] On 14 October 1996 the UGCC Synod of Bishops named Huzar auxiliary of the Archbishop Major of Lviv as coadjutor with special delegations.

In October 2007, Huzar received an honorary doctorate from the Catholic University of America in conjunction with the 100th anniversary of the first assigning of a bishop of the UGCC to the United States.

[12] In February 2008, a celebratory liturgy was held in the Basilica of Santa Sophia in Rome on the occasion of the 75th birthday and 50th anniversary of priesthood of Cardinal Huzar.

The Head of the UGCC was greeted by Pope Benedict XVI, whose address was read by the secretary of Cardinal Leonardo Sandri, Monsignor Maurizio Malvestiti.

He was honoured with the highest state award "for his outstanding personal contribution in spiritual revival of the Ukrainian nation, longstanding church work, and to mark his 75th birthday".

With failing eyesight due to poorly treated eye disease[7] forcing him to perform the church's intricate liturgical rites from memory, his early resignation was accepted on 10 February 2011[14] although normally the major archbishop serves for life.

Cardinal Huzar's resignation triggered a meeting of the Synod of the Ukrainian church, comprising its global body of bishops, to elect a new major archbishop, which must begin within a month.
