Endangered Species Act
Ontario’s Endangered Species Act, 2007 (ESA) was passed into law in 2007, and came into force on June 30, 2008. Of the 30,000 species that are native to Ontario, more than 180 are at risk. The Act defines an ‘at risk’ species as any native plant or animal that is in danger of disappearing from the province.

The Electricity Act establishes a “level playing field” for the assessment of waterpower facilities and resources to facilitate fairness in the competitive electricity market.
