London Air Quality Bylaw Guide for Contractors

Environmental Protection Ontario 3 Minutes Read · published February 12, 2026 Flag of Ontario

This guide explains how contractors working on construction sites in London, Ontario must manage air quality risks, control dust and comply with municipal and provincial requirements. It summarizes enforcement roles, practical steps for dust and emissions control, and where to submit complaints or requests for inspections. Use the official city and provincial sources cited below to confirm permit requirements and processes before mobilizing work on site.[1]

Penalties & Enforcement

Who enforces air quality and dust controls on construction sites, and what sanctions apply, depends on the instrument used (municipal by-law or provincial legislation). The City of London By-law Enforcement unit handles municipal compliance and complaints; provincial powers under the Environmental Protection Act apply to certain air pollutants and releases.[1][2]

Enforcement actions can include orders, tickets, stop-work directions and prosecution depending on the authority used.
  • Enforcer: City of London By-law Enforcement for municipal bylaws; Ministry of the Environment, Conservation and Parks for provincial matters.
  • Fines: specific monetary amounts are not specified on the cited City pages; see provincial legislation or the City for current schedules (not specified on the cited page).
  • Escalation: typically starts with notice or order, then fines, continuing offence charges or prosecution for repeat or continuing violations (details not specified on the cited City page).
  • Appeals: appeal or review routes vary by instrument; timelines and processes are not specified on the cited City pages and must be confirmed with the issuing office.
  • Non-monetary sanctions: compliance orders, stop-work directions, remediation orders and potential court action are possible under municipal or provincial authority.

Applications & Forms

The City does not publish a dedicated "air quality permit" form on its general pages; site-specific requirements (for example site alteration, dust control plans or contamination notices) are handled through existing permit and inspection processes. For definitive forms and fees, consult the City of London permit pages or contact By-law Enforcement.[1]

How-To

  1. Prepare a written dust and emissions control plan before mobilizing heavy equipment.
  2. Schedule controls for dry, windy periods and include watering, screening, wheel-wash and stabilization measures.
  3. Keep records of control measures, monitoring results and complaints; make them available to inspectors on request.
  4. Report complaints or request inspections from By-law Enforcement following the City process linked below.[1]
  5. If a pollutant release falls under provincial jurisdiction, contact the Ministry of the Environment, Conservation and Parks as applicable.[2]
Document control measures and monitor their effectiveness daily during active works.
