Invasive species are draining Canada’s economy; here’s what you can do to help

They may look harmless — even pretty, sometimes even cute — but invasive species are draining Canada’s economy by as much as $35 billion every year. From choking crops to tearing through timber, they’re putting huge pressure on agriculture, forestry, and fishing.

Not every non-native species is harmful. However, when a plant, insect, or pest threatens human health, the economy, or the environment, it’s considered invasive. Canada has more than 250 federally regulated species, and researchers are tracking over 1,400 others.
