Ontario Releases Plan to Combat Invasive Species

McGuinty Government Protecting Ontario's Economy and Environment

Ontario has developed a plan to combat invasive species in order to protect the province's environment and its economy.

The Ontario Invasive Species Strategic Plan outlines Ontario's approach to the prevention, early detection, and rapid response to new invasive species and the effective management of existing invasive species like round goby, zebra mussels and the emerald ash borer. Several ministries will work together under the plan to ensure threats to the province's biodiversity and its economy are dealt with as effectively as possible. The government has also committed to renew its partnership with the Ontario Federation of Anglers and Hunters to promote greater public awareness of invasive species through education and outreach — a major goal in the plan. Protecting Ontario against invasive species is part of the McGuinty government's plan to ensure a healthy environment and a strong economy. A strong economy protects the services that mean most to Ontario families — health care and education.

Quick Facts

  • Invasive species are species that come from other countries or regions and threaten the environment, economy or society by disrupting local ecosystems. They are the second greatest threat to Ontario's biodiversity after habitat loss.
  • Zebra mussels cost the province between $75 and $91 million per year due to economic losses in recreational and commercial fishing and boating, damages to infrastructure, and other complications resulting from the associated algae growth.
  • Since 2010, enforcement officers have seized almost 39,000 lbs. of Asian carp that were destined for Ontario markets.
  • Garlic mustard was brought over from Europe as an edible herb. It has spread throughout southern Ontario and out-competes native wildflowers such as the trillium, the provincial flower.
  • Round gobies, a fish species, are aggressive feeders and steal eggs from nesting smallmouth bass.
  • The emerald ash borer is a highly invasive insect that has killed millions of ash trees in southern Ontario. It poses a major economic and environmental threat to urban and forested areas.
  • When combined with sun exposure, the sap from the giant hogweed can cause skin to burn and inflame. In some cases, affected areas can remain sensitive to UV light years after exposure.

“Ontario's rich biodiversity supports multiple industries like tourism, forestry and recreational and commercial fishing. Invasive species are a real threat to Ontario's economic and ecological well-being. This plan paves the way for important partners like the Ontario Federation of Anglers and Hunters and the Invasive Species Centre to fight this threat together.”

Michael Gravelle

Minister of Natural Resources

“We have been fortunate to partner with the Ontario Ministry of Natural Resources for 20 years, successfully engaging millions of Ontarians annually in invasive species awareness and prevention. We look forward to building on the momentum we have gained through this partnership as we continue the delivery of Ontario's Invading Species Awareness Program into the future.”

Angelo Lombardo

Executive Director, Ontario Federation of Anglers and Hunters

“The plan serves as an excellent framework for all of us in the invasive species network to focus on priorities and work collaboratively in response to the serious ecological and socio-economic threats that invasive species represent. The Invasive Species Centre is eager to work with the Ontario government and our broad network of partners and stakeholders to deliver on key priorities.”
