Each Halloween, Oak Bay Village hosts a giant community Trick or Treat! Oak Bay Avenue merchants and the Oak Bay Municipal Hall offer treats in stores from Foul Bay Road to Monterey Avenue. A complete list of participating merchants, identified by the pumpkin poster in their window, is posted a week before Halloween on the Oak Business Improvement Association website.

Trick or Treat is held between 2 and 5 pm Halloween, October 31st. The road closure of Oak Bay Avenue between Wilmot Place and Monterey Avenue will start at 1:00 pm and conclude at 6:00 pm.
