Murray was succeeded as coadjutor by Most Reverend Philip Pocock, D.D., who became the second Archbishop of Winnipeg upon Sinnott's retirement in 1952. Sinnott spent his retirement at Camp Morton where he died at the age of 77 on Easter Sunday in 1954.
Pocock was finally successful in retiring St. Mary's debt, and a gala celebration was held to burn the last mortgage on the Cathedral in May 1952.
Also during the 1950s, St. Mary's Cemetery had to be restored following the 1950 flood. It was solemnly reconsecrated in September 1960. Pocock became Archbishop of Toronto in 1961 and died in 1984.
