"The landlord must provide tenants with their contact information such as a mailing address and physical location. That way, tenants can contact the landlord to pay rent or if they have problems with their rental unit. If the landlord fails to provide any contact information, it may be an offence under the Residential Tenancies Act."
英文不過關啊。
mailing a'daddress is "any contact information", so that's enough.
