Originally from Montreal, Chantal Prud'Homme graduated from Université de Montréal’s school of landscape architecture in 1977. She started out in City of Quebec firms Fernet & Bergevin and Pluram/Daniel Arbor & Associates before going on to spend most of her career in her private practice. She has also worked in City of Sainte-Foy public administration, Public Works and Government Services Canada and the Communauté métropolitaine de Québec.
She started her private practice in 1994, specializing in heritage and landscapes. She focuses on reconnecting communities with their past through design that pays tribute to the site's history. Her first landscape studies centred on Canada's national historic sites. She has officially evaluated several landscapes throughout Quebec at both the municipal and regional levels. She has worked with cities and groups to help them make their landscapes reflect their culture. She helped draft the Quebec manual of good practice in landscaping and the Mount Royal landscape atlas, created by the City of Montreal and recipient of a CSLA Regional Honour award in 2013.
Chantal has been actively involved with the CSLA for many years. She was president in 1988-89, then took over the dossier on professional recognition. She helped organize the Quebec landscape round table discussions in 1995 and was a delegate to the Quebec landscape council for nearly a decade. She is vice-president of the council, has contributed to the Quebec landscape charter, written a guide on landscaping and has given several courses on approaches to landscape to numerous professionals. In 1995, she received the AAPQ Frederick-Todd Award.
