These changes:

• require landlords to provide a reason to end a lease - ending ‘no grounds’ terminations for tenants
• make it easier to keep a pet in a rental home
• limit rent increases to once per year for all lease types
• prevent extra fees at the start of a tenancy, including fees for background checks and for preparing a tenancy agreement 
• ensure tenants can pay rent by bank transfer.
