The Ontario Invasive Species Act​

In 2015, the Ontario provincial government introduced the Invasive Species Act (2015), which explicitly regulates the prevention and management of invasive species in Ontario. Sixteen species are prohibited under this Act, meaning it is illegal to import, possess, transport, or release these species anywhere in Ontario. Four additional species are restricted, meaning it is illegal to bring them into provincial parks or conservation reserves and illegal to import or release them anywhere in Ontario.

Species are chosen for regulation under the Invasive Species Act based on their invasive qualities and their potential impact on the environment, the economy, and society well-being. The Ontario Ministry of Natural Resources and Forestry is currently reviewing the potential addition of 13 new species and one carrier for regulation under the Act.

Species under review for the Ontario Invasive Species Act

In early 2020, the Ontario Ministry of Natural Resources and Forestry proposed the addition of 13 new species and one carrier to the Act. The public comment period ended on April 13, 2020, and the proposal is currently under review. 

To date, the Ontario Invasive Species Act has not included pathways of spread. Under the new proposal, the Ontario MNRF is looking at regulating boating as a carrier for aquatic invasive species. This would involve regulations for the movement of boats over land and standardized Clean, Drain, Dry principles. Learn more about these developments here.
