In defense of Ontario airsoft, thats the first time I've heard of people being asked to leave the field. Once or twice people are asked to leave if they've done something very stupid, which you would reasonably expect them to leave after. Incidents of maliciously firing a BB into another player in the safe area for example. Don't judge the Ontario scene based on your first game in the area. Try other places like Wasaga and Flagraiders before you lose all hope and leave the game.
