🔑

LMR Only

Ontario only permits a last month's rent deposit — no separate security or damage deposits.

📈

Tied to the Guideline

Interest is set at the same percentage as that year's rent increase guideline — no separate rate.

📅

Paid Annually

Interest is owed on each anniversary of the tenancy, or the final period when the tenancy ends.

🏠

Final Month Only

The LMR deposit can only be applied to the last month's rent — never to damages or other arrears.
