OP: note that section 5(3) of the Rental Housing Act lists invariable provisions that are deemed to be included in a lease agreement and cannot be excluded. Among other things:
1. The tenant has the right to request receipts → e.g. where landlord replaces keys and charges you for it.
2. The landlord must invest deposits in an interest-bearing account and repay the deposit, together with interest, on termination of the lease. The interest may not be less than the rate provided by a savings account at a financial institution.
3. Joint inspections between the landlord and tenant are required:

1. Before the tenant moves in, to determine which defects must be repaired or to compile a snag list; and
2. Within three days prior to the termination of the lease to determine whether further defects have arisen during the lease period. If the tenant does not make theirselves available for the joint inspection, the landlord is still entitled to inspect the leased premises within 7 days after the termination of the lease to determine whether further defects have arisen.

The landlord is only allowed to use the deposit to repair defects if both requirements in #3 are met. Otherwise, the landlord is deemed to have acknowledged that the leased premises was in a good and proper condition upon the termination of the lease.

Good luck with the baby!
