Check local by-laws
Question and answer
Can my landlord stop me from having guests?Many cities, towns, and other municipalities have by-laws that say how many people can live in a place based on its size. Your local councillor or city hall might be able to help you find out what the says.
If you are breaking a by-law by having too many people living in your home, your landlord could tell you to ask some people to leave. If you do not, the landlord could try to you.
