9 Common Landlord Mistakes to Avoid in Toronto

Estimated reading time: 4 minutes

Owning rental property in Toronto can be a great investment, but many landlords make costly mistakes that lead to financial losses, legal troubles, and unhappy tenants.

Whether you’re new to Property Management or a seasoned landlord, avoiding these common errors can help you protect your rental income, maintain stronger tenant relationships, and stay compliant with Ontario's rental rules.

1. Not Screening Tenants Properly

Skipping a thorough screening process can result in late rent, property damage, and difficult tenancy situations.

How to Avoid It: Implement a consistent tenant screening process that includes credit checks, employment verification, previous landlord references, and a review of rental history.

2. Ignoring Ontario’s Rental Laws

Ontario’s Residential Tenancies Act regulates matters including rent increases, evictions, tenant rights, deposits, and landlord obligations.

Ignoring these requirements can lead to disputes, unsuccessful applications, or financial penalties.

How to Avoid It: Stay informed about landlord-tenant regulations and obtain professional legal advice when a situation falls outside your experience.

3. Neglecting Regular Property Maintenance

Toronto landlords must maintain rental properties in accordance with applicable property standards. Delaying repairs can frustrate tenants, worsen small maintenance problems, and potentially lead to bylaw violations.

Poor maintenance can also contribute to tenant turnover.

How to Avoid It: Conduct regular property checks and address maintenance issues promptly. A structured property maintenance process can help preserve the condition and long-term value of the property.

4. Improper Handling of Rent Increases

Ontario landlords must follow the applicable rules governing the timing, notice, and amount of a rent increase. An improperly administered increase can result in disputes and delays.

How to Avoid It: Review the applicable rules before increasing rent and use the Ontario Rent Increase Calculator when planning an increase.

Landlords generally need to provide the required written notice before an increase takes effect.

5. Skipping a Written Lease Agreement

Verbal rental agreements can create unnecessary uncertainty about responsibilities, services, utilities, and other tenancy terms.

Ontario introduced a mandatory standard lease form in 2018 to provide greater consistency and clarity for most residential tenancies.

How to Avoid It: Use Ontario’s standard lease where required and make sure any lawful additional terms are clear and properly documented.

6. Underestimating the Importance of Tenant Relations

Poor communication can turn relatively minor problems into avoidable conflicts.

A landlord who is difficult to reach or unclear about repairs, access, payments, or responsibilities may create unnecessary frustration even when the underlying issue is manageable.

How to Avoid It: Be responsive, professional, and consistent. Address concerns promptly and maintain clear records of important communications.

7. Not Budgeting for Unexpected Expenses

Unexpected repairs, legal costs, and periods of vacancy can quickly affect rental-property cash flow.

These expenses are particularly difficult for landlords who budget as though every month will produce full rent with no repairs or turnover costs.

How to Avoid It: Maintain a financial reserve for repairs, vacancies, and other unexpected expenses rather than treating the monthly rent as entirely available income.

Landlords can also use our Vacancy Cost Calculator to estimate how quickly turnover expenses can accumulate.

8. Self-Managing Without the Right Experience

Managing rental property requires time, organization, legal awareness, maintenance coordination, tenant communication, and consistent record keeping.

Self-management can work well for landlords who have the time and experience to manage those responsibilities. Problems tend to arise when an owner underestimates the workload or handles unfamiliar situations without appropriate advice.

How to Avoid It: Understand what is involved before deciding to self-manage. Owners who do not have the time or experience can consider professional Property Management for leasing, rent collection, maintenance coordination, tenant communication, and ongoing administration.

9. Asking for an Illegal Damage Deposit

Some landlords attempt to collect an additional security or damage deposit to cover possible future repairs.

Under Ontario's Residential Tenancies Act, landlords cannot simply require a general damage deposit as a condition of the tenancy.

How to Avoid It: Document the condition of the property at move-in, clearly communicate lawful tenant responsibilities, and keep records and photographs where appropriate.

If damage beyond normal wear and tear occurs during the tenancy, use the proper process to address it rather than relying on a prohibited upfront deposit.

Conclusion

Avoiding common landlord mistakes starts with consistent processes: screen tenants carefully, understand Ontario's rental rules, document agreements, maintain the property, communicate clearly, and budget realistically.

Rental properties tend to become difficult to manage when several small problems are allowed to accumulate. Good Property Management is largely about preventing those problems before they become expensive ones.
