No at the places where it might be possible to squat
I couldn't tell you unfortunately, have never had a friend that has specifically squatted
I'd imagine there are some transfem squatting spots though, purely just going off the fact that a very significant amount of transfems I've met here have either been or are homeless or found illegal living + working situations
Also fyi, I've heard of a few people being caught and taken to court though, so it's a real risk
Not sure what the outcomes or charges were
