There's a Flag Raiders Airsoft facebook group where there are game postings; outdoor games run every other Sunday and indoor games run every other Monday I believe. The outdoor and indoor games are usually hosted and run; you don't need to set it up yourself. Finch Field in Rockwood and Ultimate Paintball in Milton are some other nearby alternatives. If you don't mind going a little further, Siege Airsoft in Scarborough is always a good place to hit up, and there's Clarington Woods farther east.
