The movie was filmed at an actual summer camp, Camp White Pine, in Haliburton, Ontario (a few hours north of Toronto). Many of the extras in the film were actual campers and counselors of the camp; most if not all locations were actual camp facilities (basketball courts, mess hall, swim docks, cabins, etc.). The "Visitors Day" scene/montage was actually filmed during the camp's Visitors Day; White Pine also had a similar yearly event to the "Olympiad" - although rather than being a inter-camp competition, it was an intra-camp relay-type competition that was just part of an overall all-day themed event. These competitions were nicknamed "Mohawk Relays", perhaps serving as inspiration for the name of the rival camp in the movie.
