How Tenant Screening Works in Ontario: A Landlord’s Complete Checklist (2026)

Not automatically. Under the Ontario Human Rights Commission’s guidelines, a landlord must consider all available information holistically — including income, employment, rental history, and references — and cannot rely solely on a credit score to reject an applicant. A low score resulting from specific circumstances (e.g., a past divorce, medical debt, or a period of unemployment) does not automatically disqualify an applicant if other indicators of financial reliability are strong. Similarly, a thin or absent credit file (common for new Canadians and young renters) should not be treated as a negative factor — it requires consideration of other evidence. Rejection based purely on credit score, particularly when the applicant has strong income and rental history, can expose a landlord to a Human Rights complaint if a protected characteristic was also a factor.

No. You cannot legally require an applicant to provide their Social Insurance Number (SIN) to complete a rental application or run a credit check. Only the applicant’s full legal name, current address, and date of birth are required to pull a credit report from Equifax or TransUnion. An applicant who declines to provide their SIN cannot be rejected on that basis. Requesting a SIN creates unnecessary privacy risk and is not a legally permissible screening requirement in a residential tenancy context.

No. Refusing to rent to a prospective tenant because their income comes from ODSP, Ontario Works, CPP disability, or other government assistance is a violation of the Ontario Human Rights Code. Source of income is a protected ground in Ontario housing. You can set an income threshold that applies equally to all applicants — e.g., requiring verifiable income sufficient to pay rent — but you cannot exclude applicants whose income comes from public assistance programs. If a prospective tenant’s total ODSP or OW income meets your threshold, they cannot be declined on the basis of where that income comes from.

Yes — a lack of rental history should not automatically disqualify an applicant. Many first-time renters (young adults, new Canadians, people transitioning from homeownership) will have no rental history. In these cases, you should consider alternative indicators: employment stability, income adequacy, personal or professional references, and potentially a guarantor or co-signer. Treating no rental history as a disqualifying factor can disproportionately affect protected groups (e.g., newcomers, younger applicants) and may create Human Rights exposure.

No. The Ontario Human Rights Commission has specifically stated that applying a strict rent-to-income ratio (such as the common “rent should be no more than 30% of income” rule) as an automatic disqualifier is not a permissible screening practice. You may assess whether an applicant has sufficient income to pay the rent, but you must consider all available information — income level, income stability, credit history, rental history — rather than applying a blanket mathematical threshold that automatically excludes applicants. Using the 30% rule as a hard cutoff can disproportionately exclude low-income applicants and create Human Rights exposure.

 To verify a landlord reference, do not rely solely on the contact information provided by the applicant. Independently verify the property address — check land registry records, Google the address, or confirm through publicly available property listings — and look up the landlord’s name independently. Call the landlord at a number you sourced independently, not just the number provided on the application. During the call, ask specific questions that only a genuine landlord would know: the approximate move-in date, the monthly rent amount, whether there was a pet, what notice was given. Genuine landlords can answer these questions. Fake references typically cannot.

A guarantor can be a reasonable risk mitigation tool for applicants who have otherwise strong rental and employment profiles but a weaker or thin credit history. Under the Ontario Human Rights Commission’s guidelines, you can require a guarantor — but only if you require it consistently for all applicants who fall below a defined, objective threshold (e.g., credit score below a stated band, or income below a stated level). You cannot require a guarantor selectively from specific applicants in a way that discriminates based on a protected ground. If you require a guarantor in a consistent, documented, objective way, it is a permissible screening tool.

Retain all screening records — application forms, credit reports, income documents, reference call notes, and decision documentation — for a minimum of one year after the decision is made (whether the applicant was selected or declined). In the event of a Human Rights Tribunal complaint, which must generally be filed within one year of the alleged discrimination, you will need this documentation to demonstrate that your selection process was compliant and objective. Some landlords retain records for two years to provide additional margin.

The single most common mistake is relying on informal judgment rather than a documented, structured process. This includes skipping the previous landlord call (because the application looked fine), not getting written consent before running a credit check, accepting incomplete applications under pressure, or making a selection decision based on an intangible sense of the applicant’s character rather than documented, objective criteria. Each of these shortcuts either creates legal exposure (Human Rights complaint, privacy law violation) or misses information that a structured process would have caught. The second most common mistake is failing to document the decision — which means that even if the decision was correct and compliant, the landlord has no evidence to defend it.
