Union of Quebec Municipalities Petitions National Assembly for $500M Emergency Stormwater Adaptation Fund

MONTREAL, QC — The Union of Quebec Municipalities (UMQ), representing over 300 cities and regional county municipalities, dispatched an urgent policy petition to the National Assembly in Quebec City on Monday, demanding the establishment of an emergency $500 million provincial fund to overhaul aging municipal stormwater infrastructure.

Intensifying Flash Floods and Urban Inundation

The municipal demand follows back-to-back convective storm systems across southern Quebec that overwhelmed subterranean drainage networks, inundating over 14,000 residential basements, commercial districts, and subterranean transit tunnels in Montreal, Laval, Longueuil, and Saint-Jérôme. City engineering audits revealed that urban stormwater pipes engineered under mid-20th-century standards are structurally incapable of handling storm intensities exceeding 80 millimeters of rainfall per hour.

Montreal Mayor Valérie Plante and UMQ President Martin Damphousse stated that municipal property tax bases cannot independently absorb the multi-billion dollar capital costs required to separate combined sewer systems and install massive underground retention basins.

Provincial Climate Adaptation and Hydro-Quebec Grid Synergy

The proposed $500 million adaptation fund would provide direct municipal capital grants to construct permeable urban surfaces, daylight buried urban streams, and expand retention ponds designed to absorb intense atmospheric river runoff before it backs up into domestic sewer mains.

Municipal leaders also requested coordinated provincial planning with Hydro-Québec to safeguard subterranean electrical substations from flood infiltration, preventing cascading grid blackouts during storm emergencies.

Legislative Timetable and Parliamentary Review

Quebec Environment and Climate Change Minister Benoit Charette confirmed receipt of the municipal proposal, indicating that the government will review stormwater capital allocations within the upcoming provincial fall economic statement.
