Ontario N4 Notice Calculator

For non-payment of rent. Get your total rent owing, the correct N4 termination date, and your L1 filing steps.

Notice period for a monthly tenancy is at least 7 days after the N4 is given (rule effective Sept 21, 2026).

Only include rent (basic rent plus charges you bill separately for services like parking). Do not include the last month's rent deposit, NSF fees, or utilities paid to the utility.

General information — not legal advice. Tenant Trust is not a law firm and does not represent anyone at the Landlord and Tenant Board. Forms and rules change — confirm the current N4 and its Instructions before serving. Serving by mail or courier adds deemed-service days; this tool uses +5 for mail. Never lock a tenant out or seize their belongings.
