Storm Drain Bylaws — Ahuntsic-Cartierville Guide
In Ahuntsic-Cartierville, Quebec, proper maintenance of storm drains, gutters and connections to the municipal storm sewer reduces flooding and protects public infrastructure. This guide explains the borough and city rules that apply to private-property owners and contractors, how enforcement works, common violations, and practical steps to comply and report problems.
What rules apply
The City of Montreal and its boroughs regulate the discharge and maintenance of stormwater systems, catch basins and gutters. Property owners are generally responsible for keeping private connections clear and preventing pollutants or solid waste from entering municipal storm sewers. For official guidance on stormwater management and prohibited discharges, consult the City of Montreal resources.[1]
When maintenance is required
- Seasonal cleaning: clear leaves and debris from gutters and downspouts before spring thaw and autumn leaf fall.
- After works: inspect private lateral connections and drains after construction, paving or landscaping that alters runoff.
- When municipal notices require corrective measures for drainage that creates nuisance or risk to public infrastructure.
