Despite the sorrow and humiliations she had already experienced regarding this chapel, she set to work again with renewed energy to effect its completion, but in order to proceed with suitable solemnity, M. Souart ordered a solemn procession to be made to the place, on the 29th of June, 1673, being the Feast of the Apostles SS. Peter and Paul. A great concourse of people attended Vespers after the procession, and M. Souart, the celebrant, put a crucifix in the place destined for the altar, and the next day laid the corner-stone, in the name, and as the agent of M. de Faucamp. Sister Bourgeois labored indefatigably to procure and disburse the necessary funds, a portion of which she had received in France, as we have seen, the remainder being contributed in Ville-Marie. The Sisters themselves assisted generously out of their private funds, and others donated materials or labor which was equivalent. The interior decorations were quite elaborate, and in due course of time the church was finished to the satisfaction of every one. It was the first _stone_ church erected in Montreal, and was consecrated under the title of "Notre Dame de Bon-Secours." Mass was celebrated in it for the first time on the Feast of the Assumption, 1675, this day of Mary's glorious triumph being selected as its principal Festival. The work being thus happily completed, Sister Bourgeois, in the hope of making it contribute more effectually to the glory of God, requested the cure and church-warden of the parish to accept the new monument of piety for public use, and make it a perpetuity of the parish, in order to promote devotion to the Mother of God. The donation was of course accepted with gratitude, and confirmed by an ordinance of M. de Laval, dated November 6, 1678. Some years afterwards, by a new arrangement, dated January 17, 1700, La Fabrique gave the Sisters suitable lots for free sepulture, and the unrestricted use of the Chapel of the Infant Jesus, for their private devotional exercises, which act was approved and confirmed by M. de St. Vallier, the second Bishop of Quebec, during one of his pastoral visitations in 1719. This church of Bon-Secours served for many years as a convent chapel to the Hospitalieres of the Hotel-Dieu, when their hospital and convent was burned down in 1734, and when they were obliged to lodge their sick in the houses adjoining the church, until their re-establishment, which did not take place for three or four years.
