This alien from Europe looks like your typical daisy (sunflower family) with 10 to 20 white petals (ray florets) and a yellow disk at the centre. The leaves are another matter; they are dissected and fern like with an unpleasant odor and acrid taste. One will begin to spot them in June and will be found until the fall when the frost takes them. They like waste places and the roadside ditches usually close to the seasides of Nova Scotia.
