in the GTA there is Oasis Aqualounge in Toronto (younger crowd 20s-40s, more open vibes, has a sauna, hot tubs and heated outdoor pool, playrooms upstairs in this old 3 story mansion), you will need to sign up for first entry;
X-club in Mississauga (membership required, easy to sign up, a night club in front with some play spaces in the back, some private some open room) lots of fun even without playing but only open Fri/Sat;
M4 in Mississauga (small bar and dance floor area, 2 play areas to side/back that one is themed dungeony/BDSM and other is just leather beds/sofa, a few private rooms): have found M4 generally has way too much CSG though (creepy single guys). Much older swinger crowd, like 40s-60s, and not as fit generally. Tons of dudes compared to ladies, most of which are jerking it under their towels as they walk around half the time. Weekly gangbang night was interesting to see but had so many guys some of the girls getting played with had like 12 guys lined up, and some will push people out of the way (line cutting basically).
Haven't repeated there in a while, Oasis is out of the way but a much more chill vibe and fun crowd and M4 is good for clubbing, and maybe you get lucky. NYX is out in Oakville but I haven't been to comment on the inside/crowd.
All of them generally have some form of membership/door fee but generally its minimal for female/trans, like $10-50 versus single guys paying $100+. Thats where a lot of the CSG crowd comes in I think, they're trying to pay less to get some without seeing a provider.
