Co-operative housing member units and transitional housing programs that meet certain requirements are also excluded from the standard lease agreement. Tenants cannot require a standard lease agreement if they signed a lease before April 30, 2018, unless she and her landlord are negotiating a new lease with new terms on or after that date. Before renting an apartment or house, both the owner and the tenant want to protect themselves with a document favorable to the law. This is achieved through a housing rental agreement. This agreement is between the landlord and the Tenant(s) in Ontario. It is signed by both parties.
