Is it somehow illegal for my landlord to give out my phone number?

My neighbor was mentally challenged, and would come over all the time to hang out, which, honestly, was rather annoying (he'd stay for hours and talk constantly, and it was rather challenging to understand what he was saying, not to mention he was kindof creepy (he would make comments on how hot I am, and would try to come over as soon as my bf left for work), anyway, I just mention this so that people understand why I did not want him to have my phone number, not to be offensive, because I am sure he was mostly just trying to be friendly.). Somehow throughout all of that, we managed to prevent him from getting my phone number, without hurting his feelings, even though he asked for it a few times. Then, once we moved out, he asked my landlord, who is also his landlord, if that matters, for my phone number, and he gave it to him. So, now, my former neighbor generally calls me at least once a day, and sometimes more than that. Was it legal for my landlord to do this?

I don't think so.

I'm assuming that you signed a contract to rent from your landlord. There is also confidentiality between landlord - tenant that needs to be addressed. Your landlord might have got the wrong impression since that guy was over all the time, maybe he thought you two were friends. I would talk to your landlord, change your number.... and for the most part forget about. To go through the process in the legal system would be a nightmare!

No, nothing illegal here. I'd get caller ID and screen my calls.

depends on where you are, in canada there is a privacy act that makes it illegal without consent, but i doubt it would get any attention regardless of where you are... when there are laws in place, it's to prevent businesses from abusing things and hold them accountable... what would anyone get out of a landlord as a penalty, $100 bucks maybe? it wouldn't be worth the legal expense.... wouldn't it be easier to just tell the former neighbor not to call? you don't have to sugar coat everything for him

no, you have no case. I know it seems like you should to you, but unless your landlord signed a form stating all the info he has from you is private and can not be given out, there is nothing you can do. Should he have done it? who knows really, maybe he thought you where friends (all the visits), maybe he was vindictive, and wanted him to bother you, or maybe most likley he was indiffernt, and just gave him your number. You need to tell the old nieghbor not to call, that you do not want to continue the friendship, and if he does call again , that your boy friend will have to talk with him about not calling. this may seem hard, or harsh, but "you" have to close the door, you allowed to be opened, no one esle can do it.
