Utilities and Infrastructure Quebec 3 Minutes Read · published February 11, 2026 Flag of Quebec

Montréal, Quebec builders must follow municipal requirements for connecting new developments to water, sewer, storm, electrical and gas networks. This guide summarizes typical municipal expectations, permitting touchpoints, inspection triggers and practical steps to coordinate utilities with public works and planning authorities in Montréal. It focuses on actions developers and contractors must take before, during and after site servicing to avoid delays, fines and restoration obligations.

Overview of utility servicing requirements

New developments usually require coordinated approvals for:

  • water and sewer hookups and authorizations
  • public-domain excavation and restoration permits
  • security deposits, fees and cost-sharing for off-site works
  • engineering drawings, as-built submissions and certificates of compliance
  • coordination with utility providers (electricity, gas, telecommunications) and the borough
Start utility coordination early during design to avoid schedule conflicts.

Typical municipal steps and approvals

Procedures generally include pre-connection approvals, excavation permits for work in the public domain, inspection scheduling and acceptance of restoration works. Builders should obtain written authorization before cutting roads or connecting to mains. Detailed engineering plans signed by a professional engineer are commonly required.

  • Submit connection requests and engineering drawings to the borough or city service responsible for water and sewers
  • Obtain permits for any work that occupies or alters public domain
  • Schedule municipal inspections and provide as-built plans after completion
  • Provide required deposits or guarantees for restoration works

Enforcement of utility servicing and public-domain works is typically handled by borough or city enforcement services and the department responsible for public works and infrastructure. Specific monetary fines and escalation amounts are not specified on the general municipal guidance pages and must be confirmed with the enforcing department or the consolidated municipal bylaw text.
