<prompt> Human: So this is a short story, I live in Ontario Canada my girlfriends land lord charges her an extra 150 dollars a month on a already 1200 a month rent. If Im there for a decent amount of time out of the month. This just sort of sounds weird to me Ive not heard of something like this. If this is true is there a certain amount of days I should shy away from. Side note: she has 2 kids that arent mine. If thats of any importance occupancy wise. Thanks also if this isnt right subreddit I apologize I havent looked into something like this. Other note: Im suspicious of this landlord because hes pushed her around on some other incidences that I know hes in the wrong. Edit: her lease says 50 for additional occupants. Also I might add that I do not have my own belongings in the house I only come by frequently and stay some nights of the week.  <response>: Most leases are restricted to the named occupants and minor children and having another person move in for a decent amount of time out of the month is a violation of the lease and certainly grounds for a pay extra or else demand.x200B;
