Environmental Compliance Reports

Every year, the Ministry of the Environment Conservation and Parks publicly releases the Environmental Compliance Report on the Ontario Data Catalogue. In Ontario, all facilities with regulated wastewater discharges or air emissions under the Ontario Water Resources Act and the Environmental Protection Act must monitor and report any cases where approved operating limits have been exceeded. That information is compiled annually into the Environmental Compliance Report. Currently the latest three years are available directly below in Excel and can be viewed in CSV. Earlier years have been zipped up for ease of viewing and download. What is the report The report demonstrates how we are meeting our Made-in-Ontario Environment Plan commitment to hold polluters accountable for their actions. It includes information about steps taken by facilities to achieve compliance with environmental laws and information about ministry-led enforcement actions, including penalties and prosecutions.
