Applicable Regulations

Montreal’s Division du contrôle des rejets industriels is the department responsible for monitoring industrial discharges on the island of Montreal.  Its mandate is to ensure that air emissions and wastewater emanating from industrial and commercial sources are not prejudicial to public health, immovables, infrastructure, or to the environment in general.

This department is also responsible for enforcing water and air quality regulatory compliance on the territory of the Montreal Agglomeration.

Anyone who is inconvenienced by air pollutants such as odour emissions, smoke, fumes or dust, or who witnesses illicit dumping or other nuisances caused by the discharge of wastewater in the environment, is urged to officially register a complaint with Montreal authorities.

Making a Complaint

If you witness an infraction or a reprehensible act or practice that violates the by-laws on water and air quality in effect on the Montreal territory, please notify Montreal’s Division du contrôle des rejets industriels who will investigate and advise you of their findings.
