Each year, the Commissioner reports on environmental and sustainable development matters that he believes should be brought to the attention of the House of Commons. The reports include chapters on sustainable development strategies, audits, special studies, and since 2001 chapters on environmental petitions.
- The 2009 November Report included chapters on applying the Canadian Environmental Assessment Act, the risks of toxic substances, the National Pollutant Release Inventory, and environmental petitions.
- The 2009 Spring Report included chapters on protecting fish habitat and on the Kyoto Protocol Implementation Act.
- The 2009 March Status Report included chapters on the safety of drinking water and on the Air Quality Health Index.
- The 2008 December Report included chapters on managing air emissions, severe weather warnings, and agricultural environmental programming. The report also deals with sustainable development strategies and environmental petitions.
- The 2008 March Status Report followed up on selected recommendations and findings from prior reports. The report covered a broad range of topics, including chemicals management, the protection of species at risk and their habitats, the control of aquatic invasive species such as zebra mussels, the restoration of heavily polluted areas of concern in the Great Lakes, the use of management tools designed to get departments and agencies to anticipate and minimize future environmental problems, and actions taken in response to environmental petitions.
- The 2007 October Report included chapters on sustainable development strategies and environmental petitions. The audit of sustainable development strategies was expanded in 2007, to determine whether the strategies were serving the purpose for which they were introduced. The review of environmental petitions was also expanded in 2007 to determine whether this process is working as intended.
- The 2006 September Report deals with aspects of the federal government's approach to climate change. Issues audited include: the management of the federal approach to climate change, adapting to the impacts of climate change, and the release of greenhouse gases from energy production and consumption in Canada. The report also deals with sustainable development strategies, and environmental petitions.
