To clarify your question, can the landlord deny you from having guests, especially considering no vandalism or destruction of property occurred? The simple answer is no, they can’t. “Reasonable Enjoyment” includes the right to have the full use of a rental unit for all lawful purposes. Having guests, boyfriends, girlfriends, simple roommates, visitors is lawful and therefore part of what constitutes “quiet enjoyment” & “reasonable enjoyment” of a rental unit. Despite what your landlord may feel, having visitors is within your rights, regardless of whether or not any other person is listed on your lease either as a tenant or occupant.
Let’s look at a LTB case similar to your situation.
Cunningham v. Whitby Christian Non-Profit Housing Corp.
In this particular case the landlord served a Notice of Trespass to Property against the fiancée of the tenant in an attempt to prohibit the fiancée from entering on the premise or being on the property. The Court, in this case, held that the landlord’s action “constituted a breach of the landlord’s obligations to the tenant” (read that carefully), and the tenant was awarded a 15 per cent rent abatement for the landlord’s conduct. Now, that being said; it is NOT being suggested you can receive money over your situation. The key point is you are within your rights to have guests, providing they are not interfering with the reasonable enjoyment of other tenants (not harassing or assaulting them) and that the guests are not being destructive to the property. As a tenant, legal counsel comes at no cost if you call your local community clinch for some clarification too. Hope this helps.
