Over time, the wooden conduit of Sainte-Adèle deteriorated, and the facilities became less profitable, leading to their demolition in 1973. Two years later, the disused building of the Power Station was also destroyed. Since 1979, the site and its developments have been integrated into the Doncaster Park. On the former property of the Power Station, the municipality, in collaboration with Hydro-Québec, has developed a park that follows the path of the river and the infrastructure.
