This community was founded in Saint-Hyacinthe, Québec on September 14^th, 1861 by Reverend Mother Catherine Aurélie of the Precious Blood (Caouette) and Bishop Joseph LaRocque.

The essential purpose of this first Canadian contemplative order is adoration to the Precious Blood of Jesus and the glorification of Mary Immaculate, atonement and the reparation for the ingratitude of men who refuse to accept the gift of salvation, the practice of offering the Blood of Lamb, the performing of pious works to obtain the personal graces and those needed by the church in general as well for missionary activity.

On January 14^th, 1926 this religious community arrived in Gravelbourg to take residence in the former home of Dr. Maurice Gravel that was situated on the eastern outskirts of the town. The founding Sisters were: Reverend Mother Marie-de-la-Rédemption (LaRocque), Marie-St-Cécile (Berthiaume), Marguerite-Marie (Geoffroy), Marie-du-Précieux-Sang (Cazelais), Imelda du St-Sacrement (Nepveu), Aurélie-de-Jésus (Forcier), Marie-Eustelle (St.Hyacinthe) and Marthe. On January 19^th, Archbishop Olivier-Elzéar Mathieu blessed the new monastery. Gradually, the residence was transformed into various annexes that became a noviciate, a print shop and a room for the making of hosts. In 1928, a chapel was added to the Monastery.

The Sisters of the Precious Blood were witnesses to the outrageous acts of fanaticism and bigotry that were unleashed in the Province. Records written by the town archivist: “In May, 1928 a most solemn hommage was given to the Cross of our Redeemer in reparation for the grievous acts of profanation committed by the Klu Klux Klan on the 24^th day of May, in the vicinity of our monastery, almost before our very eyes. It was 9:30 p.m.. An evening of entertainment was in progress in the auditorium of the Collège. Nearby was held a ball sponsored by members of the Klan. Some of them put together a fifteen foot cross, raised it up and set it afire. It was said that it had been wrapped with cloth soaked in tar and so it was still burning when the guests parted from the Collège. The next day, we held a procession of reparation…”

In 1956, the population of the diocese was soon aware of the precarious condition that the residence was in. A campaign was launched and funds were raised for the renovations of the monastery in 1957.

The cloister of sisters continued to lead their penitential and prayerful life until the closing of the monastery, in 1975. Father Adrien Chabot, in his story of the diocese, described these Sisters as being the “guardian angels” and the “ostensoria” of the diocese.
