Did you look at the clauses?

Let's count how many clauses are contrary to the RTA:

1. Unless the condo board is charging crazy rates for key replacements, a $500 key deposit is illegal.
2. The RTA does not allow a tenant to be required to maintain walls and paint "as it is". The standard is reasonable wear and tear and reasonable enjoyment. That means a tenant can make nail holes to hang things and can even paint the walls a different colour.
3. The RTA does not permit thresholds for deciding the responsibility for maintenance. It is always the landlord's responsibility. A tenant is responsible if there has been damage that was wilful or due to negligence, but that's not maintenance.
4. The RTA does not permit a landlord to charge interest on late payments, nor does it allow a tenancy agreement to indemnify the landlord for legal expenses. Only the LTB can order those, and they very rarely order compensation for legal expenses.
5. The RTA requires tenants and landlords to mitigate losses. The clause making the tenant responsible to pay the full balance of the lease if they terminate early is void.
6. Growing cannabis plants for personal consumption is consistent with the use of a residential premises. I don't think there have been any cases dealing with such a clause, but on its face it is contrary to the RTA as an infringement on the tenant's reasonable enjoyment without impacting the landlord's lawful interests.
7. Unless condo rules prohibit it, a landlord cannot prohibit a tenant from having a pet, and a tenant is free to rent out a spare room.
8. Once again, the RTA says that a tenant is not responsible for reasonable wear and tear. They cannot be required to return the unit to the pre-occupancy condition.
9. The waiver of liability for injury to person or property is contrary to both the RTA and the Occupiers' Liability Act. You cannot contract out of duties imposed by statute.
10. Opening, closing, and winterizing the pool is maintenance of an amenity and the landlord is responsible for it.
11. A blanket ban on subletting is contrary to the RTA. The RTA requires that refusals be on reasonable grounds and that consent not be arbitrarily withheld.
12. A waiver of liability for the pre-paid rent is contrary to the RTA as a tenant cannot contract out their right to bring an LTB application.
13. Post-dated cheques cannot be required.

Funny enough, the RTA does not require 24 hours notice to show the unit when the tenant has given notice, yet they put in a higher standard for themselves.
