This diversity is linked to the quality of the air we breathe, the water we drink, the soils we depend upon for food, and the lands we depend on for natural resources.

Biodiversity loss – which is caused by development and habitat destruction, climate change, invasive species, hunting and pollution – is one of the most critical environmental problems facing the planet.

Although the Ministry of Natural Resources and Forestry has the most direct responsibility in fighting Ontario’s biodiversity loss, many government ministries have important roles to play. Many policies, regulations and Acts figure in Ontario’s management of plants and wildlife, including the Provincial Parks and Conservation Reserves Act, 2006, the Fish and Wildlife Conservation Act, 1997, the Endangered Species Act, 2007, and the Invasive Species Act, 2015.

Key Outstanding ECO Recommendations
  • In our 2009 Special Report on the Endangered Species Act, 2007, the ECO recommended that the Government of Ontario establish a statutory responsibility for monitoring and reporting on the state of the province’s biodiversity. Ontario still lacks baseline information and ongoing monitoring for change – both are essential components of an effective plan to conserve biodiversity.
