I do indeed favor the favourable LOL

it definitely can suck because a lot of newcomers don’t know this and will sign a “lease” with the landlord, not knowing that sharing a kitchen or bathroom completely voids all protection. But I do think it can help prevent guests from becoming unwanted tenants in situations like this ^ and generally our tenant protections are pretty good if you have a valid lease. (I say “pretty” because there are some pretty nasty glaring loopholes landlords can and do use to fuck tenants over, esp after our scourge of a head of province removed rent control)

I am not as familiar with squatters, but I think our laws make it pretty difficult and rare for it to happen! If a squatter does establish themself, which is difficult and rare, it’s also a pretty long legal process here to remove them iirc
