Invasive plants in Canada

Invasive plants are plant species that can be harmful when introduced into new areas. These species can invade agricultural and natural areas, causing serious damage to Canada's economy and environment.

Invasive plants in crops and pastures cost an estimated $2.2 billion each year by reducing crop yields and quality, and increasing costs of weed control and harvesting.
