 The municipality designated the site in 1987, shortly after the "Loi sur les biens culturel", which regulates historic preservation at the provincial level, was amended to provide specifically for municipal designation.The site was among the first to be designated by a municipality in the province, with only the North Hatley Heritage Site preceding it by a month.A few years later the Pâquet House and Notre-Dame-de-Grâce Chapel were classified as historic monuments, and subsequently restored to their better times.
