The Institute is also pursuing an infrastructure renewal project that involves abandoning the current heritage buildings, whose history dates back to 1895. The project aims to construct a new hospital that would house all of the Institute’s activities. The proposed site is located on wetlands (in the northeastern portion of the grounds), which serve as a resting area for migratory birds. This project overlooks the built and natural heritage that forms a green corridor connecting the St. Lawrence River to Angrignon Park.
The project was put on hold by the government for budgetary reasons in 2016–2017, but it remains a priority for the CIUSSS de l’Ouest-de-l’Île-de-Montréal.
In January 2020, the Ministry of Health and Social Services announced $2 million in funding for the preliminary phase of the infrastructure renewal project, which is aimed at replacing aging facilities.
