text: "Is a verbal threat a just cause for eviction?"   \n\nA threat of physical harm?  Absolutely, yes.  \n\nBut ... in order for your landlord to cover his butt and be able to take action, you will need to file a complaint in municipal court against the roommate and pursue it.  Anyone can just go and make a report, be it true or false.  A serious person also files a complaint and follows through with it in municipal court.\n\nOnce you do that, your landlord will have the grounds he needs as far as cause goes.  Where I live, a threat of physical harm goes on a 3 day notice to quit and you can file for eviction three days after the person has been served.
