An invasive plant depends on your location. What may be an invasive plant in Toronto may not be considered one in Vancouver due to differences in soil and climate. Invasive plants are typically not native to the area and they can threaten the natural habit of both plants and animals by out competing existing plants for space and resources. Invasive plants in Canada include barberry and buckthorn.
