Operating a rental property in Cambridge requires a working knowledge of Ontario's Residential Tenancies Act, 2006 (RTA) — the legislation that governs every aspect of the landlord-tenant relationship. From how much you can increase rent to how you must maintain your property to when and how you can enter a unit, the RTA sets the rules that Cambridge landlords must follow. Violating these rules can result in fines, tenant applications against you at the LTB, and complications that undermine your eviction cases.
This guide covers the key RTA provisions that affect landlords in Cambridge and Region of Waterloo, with practical guidance on compliance and how these laws interact with the eviction process. Understanding your legal obligations is not just about avoiding penalties — it is about positioning yourself for success if you ever need to evict a tenant.
Key Rental Laws Affecting Cambridge Landlords
| Law / RTA Section | What It Requires | Impact on Landlords |
|---|---|---|
| Rent Increase Guideline (s. 120) | Maximum annual increase of 2.5% for 2026 (pre-Nov 2018 units) | Must provide 90 days notice on N1 form; above-guideline requires LTB application |
| Maintenance Obligations (s. 20) | Maintain unit and property in good repair and fit for habitation | Failure triggers T6 applications, rent abatement, and eviction complications |
| Entry Rights (s. 25-27) | 24 hours written notice, 8am-8pm, for specific reasons only | Unauthorized entry is an RTA violation; emergency entry is exempt |
| Security Deposits (s. 105-106) | Only last month's rent deposit is permitted; no damage deposits | Collecting illegal deposits can result in orders against the landlord |
| Automatic Renewal (s. 38) | Tenancies continue month-to-month after lease expires | Cannot evict based on lease expiry alone |
| Prohibition on Self-Help (s. 26) | Cannot lock out, remove belongings, or shut off utilities | Fines up to $50,000 individual, $250,000 corporation |

Rent Increase Rules in Cambridge
Ontario's rent increase rules create a two-tier system that Cambridge landlords must understand. For units that were first occupied before November 15, 2018, the annual rent increase guideline applies — 2.5% for 2026. You must provide the tenant with at least 90 days written notice using the N1 form, and increases can only occur once every 12 months.
For units first occupied on or after November 15, 2018, there is no rent control. Landlords can increase rent by any amount with 90 days written notice using the N2 form. In Cambridge's tight rental market with a vacancy rate of 1.9%, this exemption allows landlords of newer properties to capture the full value of rising market rents.
If capital expenditures, extraordinary increases in property taxes, or rising operating costs justify an increase above the guideline for controlled units, landlords can apply to the LTB for an above-guideline increase (AGI) using the L5 application. The LTB evaluates the costs and may approve increases of up to an additional 3% per year above the guideline for up to three years.
Maintenance and Repair Obligations
Under section 20 of the RTA, Cambridge landlords must maintain their rental units and the property in a good state of repair, fit for habitation, and compliant with all applicable health, safety, housing, and maintenance standards. This includes:
- Structural elements: Walls, floors, ceilings, roof, and foundation must be in good repair
- Plumbing: All plumbing fixtures must function properly with adequate hot and cold water
- Electrical: Wiring must be safe and all outlets and fixtures must work
- Heating: The unit must have adequate heat — a minimum of 20 degrees Celsius from September 1 to June 15
- Common areas: Hallways, stairways, parking areas, and shared spaces must be maintained
- Pest control: The landlord is responsible for treating pest infestations including bedbugs, cockroaches, and mice
Maintenance failures have a direct impact on eviction cases. If you file an eviction application and the tenant files a T6 application alleging maintenance issues, the LTB will hear both matters together. If the adjudicator finds that you failed to meet your maintenance obligations, it can order rent abatement (reducing the rent owed) and may deny or delay your eviction under section 83. This is why maintaining your Cambridge property to RTA standards is not just a legal obligation — it is strategic protection for your eviction rights.
Entry Rights and Privacy
The RTA strictly controls when and how landlords can enter a rental unit. Under section 25, you must provide 24 hours written notice specifying the date, time (between 8am and 8pm), and reason for entry. Valid reasons include making repairs, conducting inspections, showing the unit to prospective tenants (with proper notice of lease termination) or purchasers, and other RTA-specified purposes.
Emergency entry without notice is permitted under section 26 for situations involving fire, flooding, or immediate threat to safety. However, the definition of emergency is narrow — a leaking faucet or suspected unauthorized occupant does not qualify.
Tenants who believe their privacy has been violated can file a T2 application alleging harassment or interference with reasonable enjoyment. Repeated unauthorized entries can result in orders against the landlord and complicate pending eviction cases.
Security Deposits — What You Can and Cannot Collect
Under sections 105 and 106 of the RTA, Cambridge landlords can only collect a last month's rent deposit — equal to one month's rent at the time of the tenancy agreement. You cannot collect:
- Damage deposits: Prohibited under the RTA regardless of what the deposit is called
- Key deposits: Only permitted if refundable when keys are returned
- Extra security deposits: Any deposit beyond last month's rent is illegal
- Post-dated cheques: Cannot be required as a condition of renting
The last month's rent deposit must be applied to the tenant's final month of occupancy. Each year, you must pay the tenant interest on the deposit at the rate equal to the rent increase guideline. Collecting illegal deposits can result in orders requiring you to return the money, which undermines your credibility at any future LTB hearing.
Eviction Grounds Under the RTA
The RTA provides specific grounds on which Cambridge landlords can seek eviction. You cannot evict a tenant simply because you want them out, because the lease has expired, or because you want to increase rent above guidelines. Valid grounds include:
- Non-payment of rent (s. 59): The most common ground, requiring an N4 notice with a 14-day notice period
- Interference with others' reasonable enjoyment (s. 64): Noise, behaviour, overcrowding — N5 notice with a 20-day period
- Serious damage or illegal activity (s. 66-67): N7 notice with a 10-day period or immediate termination
- Landlord's own use (s. 48-49): Personal use, family member, or purchaser — N12 notice with 60-day period plus one month's compensation
- Demolition, conversion, or major renovation (s. 50): N13 notice with 120-day period and right of first refusal
- Persistent late payment (s. 58): N8 notice — requires a pattern of consistently late payments
Each ground has specific notice forms, notice periods, and evidentiary requirements. Using the wrong ground or form is one of the most common reasons the LTB dismisses eviction applications. For detailed guidance on the eviction process in Cambridge, see our complete Cambridge eviction guide.
Illegal Eviction Penalties
Under section 233 of the RTA, self-help evictions carry severe penalties. Changing locks, shutting off utilities, removing tenant belongings, or threatening or intimidating a tenant to leave are all illegal. Penalties include fines of up to $50,000 for individuals and $250,000 for corporations. The tenant can also file a T6 application for compensation, and any pending eviction application may be jeopardized. The only lawful eviction path is through the LTB and Sheriff enforcement.
