Halloween traditions were brought to Canada by Irish and Scottish immigrants. It is celebrated in Canada on or around 31 October with costumes, parties, and door-to-door visits. Children dress up as ghosts, witches, skeletons, or characters from popular culture and visit homes in their neighborhood. The "treats" may include popcorn and candies. The jack-o'-lantern (carved pumpkin) is placed prominently on verandahs, along with spiderwebs and representations of the spirit world. Pumpkin-carving contests take place all over Canada, particularly in Nova Scotia, where whole communities compete (eg, an annual carving contest is held at Kejimkujik National Park).
