After coming to power in Yugoslavia, the Communists began to persecute him as an educated Christian and a man who occupied a prominent place under the old regime.

By the decision of the Holy Synod, he was elected Bishop of Edmonton, vicar of the Archbishop of Montreal and Canada Vitaly Ustinov.

On September 28, 1958, at The Synodal Cathedral of the Sign [ru] in New York, he was ordained Bishop of Edmonton, vicar of the Canadian diocese.

He was an admirer of Archbishop John Maximovich and helped him with legal advice during his trial in San Francisco, which ended with the full justification of the saint.

After the death of the Bishop, he collected materials about his life, which became the basis for publications of his work "Orthodox Russia", and then for the book "Chronicle of the veneration of Archbishop John Maximovich."

Metropolitan Hilarion Kapral, whom Bishop Sava inspired to accept monasticism, recalled that he was a man of high spiritual life, always referred to the patristic teaching in the conversations and was unusually kind.
