Rousseau Lefebvre

What Rousseau Lefebvre does

Rousseau Lefebvre is a Quebec-based landscape architecture and environmental planning firm founded in 1989 by Michel Rousseau and Daniel Lefebvre. The firm delivers professional services in urban design, town planning, sustainable landscape architecture, and project management for government, municipal, institutional, commercial, healthcare, education, industrial, and ecotourism clients, primarily across Quebec. Its core differentiation rests on biophilic design and climate-change adaptation, operationalized through proprietary tools including the Grille d'aménagement durable (GAD) decision-support framework, the Plan directeur d'aménagement biophilique master-planning service, OPTI Entreprise and OPTI Territoire eco-responsible optimization engagements, and the CC LAB climate-change experimentation laboratory established in 2022 with monitored biodiversity plots.

The firm employs approximately 30 multidisciplinary professionals organized under 8 associates, holds LEED and SITES accreditations, and has been recognized for R&D by provincial and federal authorities since 2004. Its portfolio includes landmark Quebec projects such as Projet Bonaventure (the first SITES v2-certified project in Canada), the 200+ km Parc des Grandes-Rivi\u00e8res-de-Qu\u00e9bec riverbank plan, the Carrefour Laval 10-year master plan, Cadillac Fairview's Galeries d'Anjou redesign, CISSS Laval's H\u00f4pital Cit\u00e9-de-la-sant\u00e9 courtyard, and Lab \u00c9cole de Chicoutimi.

Rousseau Lefebvre generates revenue through fee-for-service professional consulting (feasibility studies, strategic development plans, site planning, project management, environmental diagnostics) sold primarily via direct engagement with government agencies responding to public tenders and with institutional/commercial clients through direct proposals. Pricing is project-specific and not publicly disclosed. Recent commercial expansion has introduced OPTI Entreprise to corporate organizations and a partnership with FAQDD to channel clients toward the new \u00c9coleader - Biodiversity fund, broadening the customer set beyond traditional design clients. The firm operates from headquarters in Laval and a secondary office in Montr\u00e9al, remains privately held under founder and associate ownership with no external investment or parent company, and supports its market presence through industry awards (AAPC, Cecobois, OAQ, Frederick-Todd), conference participation, and project-based content marketing.
