Marie-Pier Leroux is a lawyer practising public property law at De Grandpré Chait, where she has worked since beginning her legal career in 2021. Her practice focuses on expropriation, urban planning and land use planning.
She assists real estate developers, builders and landowners with their projects and in complex real estate litigation involving questions of statutory and regulatory interpretation.

Marie-Pier draws on her organizational skills, critical judgment and investigative mindset to conduct a rigorous and detailed analysis of the issues in each case. Keeping abreast of developments in the real estate market and the legislative and regulatory framework, she devises creative strategies tailored to her clients’ needs to protect their rights, seek fair compensation and help them make informed decisions.
Accessible and responsive, Marie-Pier places teamwork at the heart of her approach. She works closely with her colleagues in the Public Property Law group, ranked Band 1 by Chambers Canada in Real Estate: Zoning in 2026, to put her expertise and experience to work for her clients, helping them focus with confidence on bringing their projects to fruition and helping shape Québec’s development.
