I went today with some friends for the first time in years. Not too bad there but some things to point out. Small dark field, the walls have never scrapped, making them extremely slimy. The staff at the counter were really nice, but the ref did nothing during to game to actually control it. Lots of cheating, some bad sportsmanship. I haven't played paintball in 6 years and after visiting today I remember why I stopped.
I would recommend travelling a little outside to the GTA to play at Flag Raiders paintball in Kitchener.
