Environmental Protection Ontario 3 Minutes Read · published May 26, 2026 Flag of Ontario

In St. Catharines, Ontario, residents and businesses should report visible vehicle or industrial emissions, persistent smoke, or odours that may affect health or the environment to municipal Bylaw Services and the province as appropriate. This guide explains who enforces emissions complaints, how to report with evidence, typical enforcement actions, and what to expect after you file a complaint. Use the official city reporting tools first for local bylaw matters, and contact provincial authorities for environmental pollution that may require Ministry intervention.

Report visible smoke or strong odours promptly and note time, location and direction.

How to report emissions

Collect basic information before you report: date, time, exact address or intersection, direction of smoke or odour, photos or video, vehicle description or industrial site details, and any health effects. Then submit the report using the official city form or by phone; escalate to provincial reporting if the incident appears to be a pollution event rather than a local bylaw issue.

  • Note the date and time of the observation and how long it lasted.
  • Take photos or short video showing smoke, plumes, or vehicle emissions.
  • Record descriptions: vehicle make/model/plate, business name, stack location, wind direction and nearby sensitive receptors.
  • Submit an online complaint or call the city reporting line to document the incident officially.
