The bulk of your rights and responsibilities as a tenant are set by Ontario law rather than your rental agreement.
However, some items are left to you and your landlord to decide on, such as :
How much rent will be paid
What services and facilities are included in your rent
You expected move-in date
The expiry date of your lease, if you have a fixed-term tenancy
How can I get my landlord to use the standard lease form?
Since April 30th, 2018, all rental agreements must be signed using a standard lease form.
Do I have to pay a deposit when I rent a new place?(Ontario)
Your landlord may require you to pay a rent deposit as well as a key deposit.
The reRent nt deposit cannot exceed one month’s rent on a yearly or month-to-month rental, or one week’s rent on a weekly rental. It must be used for your final period of rent. It cannot be used to cover any damages or other costs.
A key deposit cannot be more than the actual cost to replace the keys. If you return the keys once you move out, the landlord must give you back this deposit.
However, the landlord cannot ask you for any other kind of deposit.
