Insects

Prevention is the most effective way for the Canadian Food Inspection Agency (CFIA) to protect the plant resource base. However should a pest become introduced in Canada, the Agency's goal is to reduce its impact.

The following factsheets have been developed to promote public awareness and encourage reporting of suspect sightings of these species that have the potential to be invasive in Canada, some of which are regulated under the Plant Protection Act. For the full list of regulated pests, visit the Pests regulated by Canada page.
