The N4 Notice to End Tenancy Early for Non-Payment of Rent is the most commonly used form in Ontario's rental market, yet it's also the most frequently botched. A single error in completing this critical document can result in your entire eviction application being dismissed, forcing you to start the process over again—often costing months of additional unpaid rent.
Based on extensive analysis of Landlord and Tenant Board (LTB) decisions, this guide reveals the most common N4 notice errors and provides step-by-step instructions to avoid these costly mistakes.
Understanding the N4 Notice
The N4 notice serves a dual purpose: it formally demands payment of overdue rent and provides legal notice of tenancy termination if payment isn't made. Under Ontario's Residential Tenancies Act, landlords cannot proceed with eviction applications without first serving a valid N4 notice.
Legal Requirements
For an N4 notice to be valid, it must:
- Accurately identify the rental unit and tenant(s)
- Correctly calculate the amount of rent owing
- Provide proper termination dates with adequate notice periods
- Include only amounts that qualify as "rent" under the Act
- Be properly signed and served
Failure in any of these areas renders the notice defective and your application doomed to failure.
The Most Costly N4 Notice Errors
1. Including Future Rent or Non-Rent Amounts
The Error: Including rent that isn't yet due or amounts that don't qualify as "rent."
In Kim-v-Martineau-20210902, the landlord's application was dismissed because "the N4 notice issued by the Landlord was defective as it included an amount that was not yet in arrears as of the date the N4 was issued."
Similarly, in peel-housing-corp-oa-peel-living-v-firlotte-20231110, the N4 notice was found defective because "it included amounts that were not considered 'rent' under the Residential Tenancies Act, 2006."
The Fix: Only include rent that is actually overdue as of the date you're preparing the N4. Never include:
- Future rent payments
- Late fees or NSF charges
- Utility bills (unless specifically included in rent)
- Property taxes or insurance
- Damage deposits or other non-rent charges
2. Incorrect Rent Calculation and Periods
The Error: Miscalculating the total amount owing or incorrectly identifying rental periods.
In Patel-v-Weatherhead-20211223, the N4 notice was defective because "it did not correctly set out the amount of rent owing by the Tenant for the period claimed."
The case Godarz-Vand-Chegini-v-Hossein-Zadeh-20220304 shows another common error: "The N4 notice had an incorrect rental period, which made it defective and prevented the Board from terminating the tenancy."
The Fix:
- Double-check your math on all calculations
- Clearly identify each rental period with specific dates
- Ensure rental periods align with your actual rent collection schedule
- Account for any partial payments received
3. Improper Service and Timing
The Error: Failing to provide adequate notice periods or serving the notice improperly.
In Perri-v-Agawa-20211029, the N4 notice was invalid because "it did not provide the Tenant with at least 14 days' notice prior to the termination date as required by the Residential Tenancies Act, 2006."
The case Kenlar-Investments-v-Sheppard-20210302 demonstrates service issues: "The N4 Notice was not validly served as the Landlord was only able to slide it partially under the Tenant's door, which was blocked."
The Fix:
- Ensure at least 14 days between service date and termination date
- Use proper service methods (personal service, mail, or posting)
- If posting under a door, ensure the entire document goes through
- Keep detailed records of service method and date
4. Missing or Incorrect Signatures
The Error: Failing to properly sign the N4 notice.
In Caron-Van-Hooren-and-Vern-Bolton-v-Michael-Dungy-20211025, "The N4 notice was not signed by the Landlord, making it incomplete and fatally flawed."
The Fix:
- Always sign the N4 notice before serving it
- Ensure the signature matches the landlord name on the lease
- If using an agent, ensure proper authorization is documented
- Never serve an unsigned notice
5. Incorrect Tenant or Property Identification
The Error: Failing to properly identify the tenant(s) or rental unit.
In VC-v-AC-RSL-MSS-AS-MS-DSB-20180427, "The N4 notice of termination was found to be defective as it did not correctly identify the rental unit."
The case Kang-v-Marques-Sousa-20220304 shows another identification issue: "The N4 notice was found to be invalid as it only identified one Tenant's email address and did not specify who the Tenants were."
The Fix:
- Include all tenant names exactly as they appear on the lease
- Provide complete and accurate rental unit address
- Include unit numbers, apartment numbers, or other identifying details
- Ensure consistency with lease documentation
6. Improper Payment Application
The Error: Applying tenant payments to non-rent items instead of rent arrears.
In peel-housing-corp-oa-peel-living-v-firlotte-20231110, the landlord "applied the Tenant's rental payments to other invoices instead of the rent arrears, which did not correctly afford the Tenant the opportunity to void the N4 Notice."
The Fix:
- Always apply payments to rent arrears first
- Maintain clear records of payment application
- Don't offset rent payments against other charges without tenant agreement
- Ensure the N4 reflects actual unpaid rent after proper payment application

Step 4: Complete the Form
- Fill in all required fields completely and legibly
- Include only amounts that qualify as "rent"

Step 5: Serve the Notice

Common Misconceptions About N4 Notices
"I Can Include Late Fees"
Wrong. Late fees, NSF charges, and administrative fees are not "rent" under the Residential Tenancies Act and cannot be included in N4 notices.
"Partial Payment Voids the Notice"
Not Necessarily. The tenant must pay the full amount specified in the N4 to void it. Partial payments don't automatically void the notice but may affect your calculation for future notices.
"I Can Serve It Anytime"
Wrong. You can only serve an N4 after rent is actually overdue. You cannot serve it for future rent or on the day rent is due.
"Email Service is Always Valid"
Not Always. Email service is only valid if specifically agreed to in the lease or if other service methods have failed.
Red Flags That Indicate Problems
Watch for these warning signs that may indicate N4 issues:
- Tenant disputes the amount: May indicate calculation errors
- Questions about service: Could signal improper service method
- Challenges to rental periods: May indicate incorrect period identification
- Payment application disputes: Could indicate improper payment handling
What Happens When N4 Notices Fail
When an N4 notice is found defective, the consequences are severe:
- Application dismissed: Your entire eviction application fails
- Start over: You must serve a new, correct N4 notice
- Lost time: Additional months of unpaid rent accumulate
- Legal costs: Wasted application fees and potential legal expenses
- Tenant leverage: Tenants gain additional time and negotiating power

Conclusion
The N4 notice is your gateway to the eviction process, but it's also a potential roadblock if completed incorrectly. The cases examined reveal that even experienced landlords make critical errors that result in dismissed applications and months of additional lost rent.
Success requires meticulous attention to detail, accurate calculations, proper service, and strict adherence to legal requirements. Every field must be completed correctly, every calculation must be accurate, and every procedural requirement must be followed.
The cost of errors is simply too high to risk shortcuts or assumptions. When dealing with N4 notices, precision isn't just important—it's essential for protecting your rental income and maintaining successful tenancies.
Remember: it's far better to take extra time ensuring your N4 notice is perfect than to face the costly consequences of starting the entire process over again. In Ontario's rental market, attention to detail in notice preparation often determines the difference between successful rent collection and months of financial losses.
