Born in Malta in 1960, Fr Mario joined the Missionary Society of st Paul in 1978.
During his formation years in Malta, he studied philosophy at the Faculty of Theology in Rabat, and completed his B.Ed.(hons) course at the University of Malta. In 1986 he had the opportunity to have a few months of missionary experience with the MSSP missionaries in Peru.
In the beginning of 1987 he went to Australia and completed his theological studies at Catholic Theological College in Melbourne. Fr Mario was ordained to the priesthood on November 30, 1990.
Following his ordination, Fr Mario continued to minister in Australia, mostly at St Bernadette's Parish in Nth Sunshine, and at St Paul's Spirituality Center at Wantirna Sth, which was under the care of the MSSP. From this place the Paulist fathers also reached out as chaplains to the Maltese community of the south-eastern suburbs of Melbourne.
During the MSSP General Chapter of the year 2000 Fr Mario was elected as one of the Councillors to assist the Superior General in the running of the Missionary Society of St Paul. He, therefore, moved to Rome, Italy, where for 18 years he held various responsibilities within the MSSP General Council.
In the beginning of 2019 Fr Mario came to Toronto, where on the 25th of January he began his ministry as Pastor of St Paul's. His years of ministry with the Maltese community in Australia, as well as his wider experience whilst in the General Administration of the MSSP in Rome, will surely be great assets which assist Fr Mario in his ministry with the Maltese-Canadian community of Toronto.
