Hundreds of invasive species of plants, animals, and marine life have become established in Ontario.

  Not all non-native species are invasive. Invasive species are defined as harmful alien species whose introduction or spread threatens the environment, the economy, or society, including human health. Once established, invasive species can be extremely difficult and costly to control and eradicate, and their ecological effects are often irreversible.
