I have played in Ottawa, Toronto, Timmins, and both North Bay fields.
Chris and Russ run a great paintball park. staff is always extremely friendly, great location. Pricing is just right plus the proshop in town that can get you what you need.
I have playing there since they bought this field. Just what Sudbury needed. Plus they run a great league called the Northern Ontario Paintball League (NOPL) which lots of teams from the north attend. so if you are into woodsball , recball, or speedball they have it all.
