By 1945, Fr. James Fleming SJ became the director and with the number of retreatants growing decided to establish a permanent centre. A building was bought in Erindale, Mississauga. It was named the Manresa Retreat House Centre, after Manresa in Spain, where the founder of the Jesuits, Ignatius of Loyola stayed in solitude for a year. It opened in November 1946 and had accommodation for eighteen retreatants.
