Understanding the N1 Notice
What Makes N1 Ontario’s Most Used Notice
The N1 Notice of Rent Increase represents the foundation of sustainable property management in Ontario. Unlike other provinces where market rates prevail, Ontario’s rent control system requires precise adherence to guidelines and procedures through the N1 form.
Every year, over 400,000 N1 notices are served across the province, generating approximately $480 million in additional rental income for property owners. Yet recent data shows that improper N1 service costs landlords millions in lost revenue opportunities.
The Legal Framework Behind N1
The Residential Tenancies Act governs rent increases through a carefully balanced system:
- Protection for tenants from excessive increases
- Predictability for landlords in revenue planning
- Standardization across all controlled units
- Exceptions for newer buildings and special circumstances
For modern property management companies, understanding these nuances determines whether rent increases proceed smoothly or face challenges that can delay revenue for months.
Why Precision Matters More Than Ever
The Cost of N1 Errors:
- Invalid notice: Must wait another 90 days
- Calculation mistakes: Potential LTB orders to repay
- Timeline errors: Full year delay possible
- Wrong form version: Complete invalidity
Professional property management software eliminates these risks through automated compliance checking and calculation verification.
2025 Rent Increase Guidelines
Understanding the 2.5% Limit
The 2025 guideline of 2.5% represents the maximum allowable increase for most residential units without additional approval. This rate, set annually by the Ontario government, reflects economic factors including inflation and operating cost changes.
Calculating Your Increase
For Monthly Rent of $2,000:
- Maximum increase: $50 (2.5%)
- New rent: $2,050
- Annual impact: $600
For Monthly Rent of $1,500:
- Maximum increase: $37.50 (2.5%)
- New rent: $1,537.50
- Annual impact: $450
Automated rent calculators ensure accurate calculations across entire portfolios.
Historical Context and Trends
Year | Guideline | Economic Context |
2025 | 2.5% | Moderate inflation period |
2024 | 2.5% | Stabilization post-pandemic |
2023 | 2.5% | Recovery phase |
2022 | 1.2% | Pandemic support |
2021 | 0% | Rent freeze |
Understanding these trends helps property managers plan long-term revenue strategies.
Above Guideline Increases (AGI)
While N1 limits increases to 2.5%, landlords can apply for above-guideline increases through separate LTB applications for:
- Extraordinary operating cost increases
- Capital expenditures (major repairs/upgrades)
- Security services additions
AGI applications require extensive documentation and face scrutiny, making the standard N1 increase more predictable for most properties.
Eligibility Requirements
The Four Pillars of N1 Eligibility
1. Twelve-Month Rule
You cannot increase rent until:
- 12 months have passed since tenancy began, OR
- 12 months since the last rent increase
Common Confusion Points:
- Date counts from when tenancy started, not lease signing
- Previous landlord’s increases count toward 12-month calculation
- Rent reductions don’t reset the clock
Tenant tracking systems automatically monitor eligibility dates across portfolios.
2. Unit Must Be Covered Under Rent Control
Rent-Controlled Units Include:
- Buildings first occupied before November 15, 2018
- Social housing units
- Nursing homes
- Mobile home parks
Exempt Units (Use N2 Instead):
- First occupied after November 15, 2018
- Additions to existing buildings after November 15, 2018
- Some converted commercial spaces
3. Proper Tenancy Status
Eligible Tenancies:
- Active month-to-month
- Fixed-term leases
- Renewed tenancies
- Continued occupancies
Ineligible Situations:
- Vacant units
- Between tenancies
- Under eviction proceedings
- Unauthorized occupants
4. Compliance with Previous Obligations
Before serving N1, ensure:
- All maintenance obligations met
- No outstanding LTB orders against you
- Previous rent receipts provided
- Required documents delivered
Compliance tracking features help maintain eligibility across multiple properties.
The 90-Day Timeline
Precision in Timing Calculations
The 90-day notice requirement is absolute and unforgiving. Even being one day short invalidates the entire notice.
Breaking Down the Timeline
Day 0: Service Date
- The day you serve the N1
- Must be documented precisely
- Not included in 90-day count
Days 1-30: Early Period
- Tenant processes increase
- Questions typically arise
- Payment method updates needed
Days 31-60: Preparation Phase
- Tenant budget adjustments
- Pre-authorized payment updates
- Communication about changes
Days 61-89: Final Preparation
- Reminder communications
- System updates
- Final clarifications
Day 90: Earliest Effective Date
- Must align with rental period
- Cannot be mid-month for monthly tenancies
- First increased payment due
Calculating Effective Dates
For Monthly Tenancies: If serving N1 on March 1, 2025:
- 90 days = May 30, 2025
- Effective date: June 1, 2025 (next rental period)
If serving N1 on March 15, 2025:
- 90 days = June 13, 2025
- Effective date: July 1, 2025 (must be full rental period)
Automated timeline calculators prevent costly date calculation errors.
Service Method Impact on Timelines
Service Method | Additional Days | Total Notice Period |
Hand delivery | 0 | 90 days |
Under door/mailbox | 0 | 90 days |
+5 days | 95 days | |
Posted on door | 0 | 90 days |

N1 FAQs
Timing and Calculation Questions
Q: Can I increase rent by less than 2.5%? A: Yes, you can increase by any amount up to 2.5%. Some landlords choose smaller increases to maintain tenant satisfaction.
Q: What if my tenant’s lease renews mid-year? A: Lease renewal doesn’t affect rent increase eligibility. The 12-month rule applies regardless of lease terms.
Q: Can I serve N1 during a fixed-term lease? A: Yes, as long as the increase takes effect after 12 months of tenancy, even within a fixed term.
Service and Compliance Questions
Q: Is email service valid if my tenant agrees? A: No, even with agreement, email isn’t recognized for N1 service. Physical delivery is required.
Q: What if I made an error on the N1? A: You must serve a new, correct N1 with a fresh 90-day notice period. The original is void.
Q: Can tenants refuse the increase? A: No, properly served N1 increases are mandatory. Tenants can only move out if they object.
Special Situation Questions
Q: How do I handle partial month tenancies? A: Prorate the increase for partial periods using daily calculations based on the number of days in that month.
Q: What about tenants who pay quarterly? A: The same rules apply, but ensure 90 days notice before the next quarterly payment date.
Q: Can I increase parking separately? A: If parking is a separate agreement, it may not be subject to rent control. If included in rent, it’s part of the controlled amount.
Legal compliance tools help navigate complex situations correctly.
