The Lake Edward Sanatorium was created to treat tuberculosis patients before the availability of antibiotics and was long the main employer in Lac Édouard village. Its history covers a century, from 1904 to 2004, but its mission changed in 1968. The hospital complex is situated at the end of Lake Edward Village in "Haute Mauricie", in the province de Québec, Canada. The complex is built on a peninsula, north-east of lake Edward, 28 km long, at the head spring of Batiscan river. In 1904, there was no road, no electricity and no telephone. The nearest city was 179 km away by railway. Most of the buildings still exist.
