Recently, during the 10 o’clock Mass, celebrated by Robert Gagné, a Sulpician priest, Mother Marie-Rose Durocher was officially recognized as "Secondary Patron" of the parish of St-Arsène. The parish, located in the Montreal borough of Rosemont-La Petite-Patrie, had issued an invitation to parishioners in the weekly bulletin, under the title "We are celebrating Marie-Rose Durocher".
For this special celebration, the Sisters of the Holy Names of Jesus and Mary from Marie-Rose-Durocher Residence, across the street from the parish, provided the singing during the Mass dedicated to their foundress. Sister Monique Thériault accompanied them on the organ.
