Montréal, Quebec homeowners and property managers often need to know who maintains storm drains and when cleaning occurs. This guide explains how municipal schedules and bylaws affect neighbourhood storm sewer maintenance, how to report blockages, who enforces rules, and practical steps to get repairs or cleaning arranged through city services.

How schedules and maintenance work

The City of Montréal manages storm sewers and culverts through its municipal services and arrondissements. Maintenance frequency depends on network type (trunk lines, local sewers, inlet grates) and local priorities; specific weekly/monthly schedules are published by local boroughs or announced during seasonal programs. For properties with private storm connections, owners may have maintenance responsibilities under municipal bylaws.

Reporting & Contacts

To report a blocked or damaged storm drain, contact the city 311 service or your borough office. For urgent flooding, call emergency services first. Use the city reporting tools or your arrondissement contact page to request inspection or urgent cleaning.

  • Report problems via the City of Montréal 311 online or phone service.
  • Check your borough (arrondissement) page for scheduled cleaning notices and local contacts.
  • Keep photos and location details to help crews assess priority.
