The first building on this site, erected sometime in the 1870s, was the home of Joseph Lemay. On his death in 1892, it was donated to the local church and in 1903, Father Noël-Joseph Ritchot arranged the donation of the building and surrounding land to les Soeurs de Misericorde, who operated it as an orphanage from 1904 to 1948. In 1911, they undertook a major expansion, constructing the present three-story brick building.
When Asile Ritchot closed in 1948, the building was used as a seminary by the Oblate Order. In 1970, the X-Kalay Foundation (later renamed the Behavioural Health Foundation) began using it for the treatment of people with drug or alcohol addictions.
