You can get a lot of the gears you need/want from the forums here. There's quite a few sellers here that carry a very wide range of selection. Just prepare to spend the $$$.
In Ontario, we are already very lucky to have so many fields, TTAC3, EOTECH like you mentioned, there are also Wasaga (up by Barrie/Wasaga Beach area), Flag Raiders west in Cambridge (they got 2 fields there, new + old). I believe someone still plays a few games at Sgt Splatters, but numbers have drastically dropped there. Airsoft isn't exactly like a movie theatres, you won't find much fields (if any other than TTAC3) in urban centres.
You might want to get yourself verified and open up yourself to our awesome classified sections.
