On August 4, 2026, the Communauté métropolitaine de Montréal formally asked the provincial government of Quebec for assistance in a project that will identify and map buildings most vulnerable to flooding. The request was made jointly with Mayor Soraya Martinez Ferrada, who highlighted the need for coordinated action.

The initiative seeks provincial support to produce a detailed inventory of structures that lie in zones prone to inundation. By creating a geographic database of high‑risk properties, local authorities hope to improve planning, emergency response, and future mitigation measures across the metropolitan area.

Recent years have seen a noticeable increase in heavy‑rain events that have triggered more frequent flooding throughout Montreal. The surge in flood incidents has strained municipal resources and raised concerns about the safety of residential and commercial properties located in low‑lying neighborhoods.

Officials from the CMM argue that a comprehensive mapping effort is essential for understanding the scope of the problem and for guiding investment in infrastructure upgrades. The collaboration with the Quebec government is intended to leverage provincial expertise and resources to address the growing climate‑related challenges facing the city.

The request marks a step toward a coordinated regional response, reflecting the urgency expressed by city leaders as Montreal continues to confront the impacts of intensified rainfall patterns.

The Communauté métropolitaine de Montréal, which oversees regional planning and development, coordinates the effort on behalf of the surrounding municipalities. By partnering with the provincial administration, the project aims to pool data and analytical tools that are currently available at the Quebec level.
