Lubomyr Husar was 84 years old, TSN reports.
He was the major archbishop emeritus of the Ukrainian Catholic Church, a minority church in Ukraine but the largest sui juris Eastern church in full communion with the Holy See.
Born in Lviv, Husar fled with his parents in 1944 during World War II. They briefly lived in Salzburg, Austria, then emigrated to the United States in 1949.
On March 30, 1958, he was ordained a priest for the Ukrainian Catholic Eparchy of Stamford.
In December 2000, Pope John Paul II named Husar apostolic administrator of the Ukrainian Greek Major-Archeparchy of Lviv, and in January 2001 the Ukrainian Greek synod elected him Major Archbishop. On February 21 of that year, Pope John Paul II created and proclaimed Husar Cardinal-Priest of Santa Sofia a Via Boccea.
After the transfer of the see of Lviv to Kyiv in 2005, he was the Ukrainian Catholic Major Archbishop of Kyiv-Halycia.
In February 2011 he became Major Archeparch Emeritus after he resigned due to health issues.
