The City of Ontario invites ages 18 & older to enter the car trunk decorating contest. A registration fee of $20 helps defer costs and you're provided the candy to distribute to kids who go car to car trunk or treating. The event is incredibly fun for all ages.

Kids can participate free and can come in costume to go trick or treating at car trunks in the Westwind Parking Lot. These are not just any car trunks. They are decorated in themes and designs for Halloween.

Other fun events in Ontario include the free summer concerts and Easter Egg Hunts.

Events are not guaranteed. It is your responsibility to confirm before going.
