Invasive Species

Invasive species are widespread in Toronto and pose one of the main threats to biodiversity in our natural areas.  Essentially this means that our native birds, insects and mammals that require natural areas to survive have a difficult time finding shelter and food in our natural landscapes.

Under the Ontario Invasive Species Act actions must be taken “to slow and where possible reverse the spread of existing invasive species, and to reduce the harmful impacts of existing invasive species.” A number of restricted species are identified in the Regulation.
