In Pickering off the 401 like everyone else has posted.
This is a really professionally run field. The staff are helpful and actually are interested (unlike the impression you get at several competing fields in the area).
I have played twice here on Wed night half price days. As a gun owner the way to go is BYOP and play in the open class (provided your comfortable playing some fast shooting games with lots of paint flying around), If you are new to the game playing in the lower "owner class" with field paint provides a slightly less intense game experience suitable for greener players. The field is kept pretty clean and bunkers have been in different locations the two times i've been there which is nice for a change (they even have moved them mid way thru my play session to change things up a bit both times.
My first time playing here i had a great time, 2nd time around i ran into a few poor sports. One that had a temper tantrum that i shot him at the same time as another player landing a hit as he thru up his arm, sorry buddy but i can't stop a shot thats in mid flight, instead of walking off the field he stood up walked around so he had a clear shot on me and fired 3 rounds into my facemask (BOOOO!) then walked around behind the netting to hide hahaha. The other issue i had was with a player shooting hot, i ran thru a doorway in a bunker and got lit up by what felt like ball bearings from about 10ft away, actually left a cut on my head and leg. I approached the player about him possibly shooting hot, after getting no acceptable response from that guy about going to the crono i spoke to a Staff member and too the fields credit they made him Chrono in and sure enough he was shooting 305fps. I think they kicked him off the field for the night because i never saw him again. Good Show Next Paintball. Lets keep the game friendly everyone, we all want to be competitive but were all here for a good time also.
In both my outings i've run across a few cool players to chit chat with in the staging area and almost all of the players are friendly, call hits when there hit and play some good paintball forcing you to play well also. This is a good field to go to, and is currently my field of choice.
