“It is equally important for the government of Ontario to take all necessary measures to control this noxious and invasive weed on provincial lands such as our highway corridors,” writes Webster. “We fully expect individuals and all governments to respect the law and fulfill their responsibility to control these weeds, including wild parsnip. It’s what we need to put the needs of our farm workers, rural residents and Ontarians ahead of this weed.”
