Our Church is named after St. Jerome of Stridon who lived between 345-420 A.D. He is known as the most prominent Scripture scholar and one of the most learned doctors of the Church. St. Jerome translated the Old Testament from Hebrew text to Latin, and the New Testament from Greek text. His commentaries on the Scriptures are hallmark, especially his treatise against Helvidius on the perpetual virginity of Our Blessed Lady.
His Eminence, Aloysius Cardinal Ambrozic, signed the Decree of Erection for the Parish, in the West part of Brampton, on August 14, 1990. Fr. Vid Vlasic was appointed founding Pastor on July 1, 1990 and took up the residence on 273 Elgin Drive. Since the Church building was not constructed at the time, in the first year of the parish's life, Mass was being celebrated in the gymnasium of St. Brigid's School. After the opening of St. Augustine High School in September of 1991 all our celebrations were held in their Cafetorium and Chapel until the completion of the church. The sod turning ceremony took place on Sunday, February 23rd 1997, and construction began in January of 1998. The first mass was celebrated on Saturday September 5th 1998 with our the regional bishop of the time, Bishop Terrence Prendergast S.J.
Our new church was Dedicated by His Eminence Cardinal Ambrozic on the Feast of All Saints, November 1st 1998.
