Tenant Screening in Ontario: Best Practices

The tenant in your unit determines almost everything that happens next. Bad tenants compound — missed rent, property damage, condo board complaints, LTB filings can erase years of returns. Good screening doesn't guarantee a good outcome, but it tilts the odds dramatically.

‍

What you can ask for

Ontario landlords can lawfully request: a completed rental application, government-issued identification, employment information, income verification, prior-landlord references, and consent to a credit check. SingleKey-grade screening tools also offer reference scoring and ID verification.

What you can also do: ask follow-up questions during showings, observe how applicants treat your time and the unit, and follow your gut when something doesn't add up.

What you cannot consider

Ontario's Human Rights Code prohibits discrimination based on race, ancestry, place of origin, colour, ethnic origin, citizenship, creed, sex, sexual orientation, gender identity, gender expression, age, marital status, family status, disability, or receipt of public assistance.

You also cannot impose a higher rent or different terms based on these factors. The fair-housing rules are robust and the Human Rights Tribunal of Ontario takes complaints seriously.

Income and rent ratios

A common rule of thumb: total household income should be at least 3x the monthly rent. This is a guideline, not a rule — some applicants with strong reference histories and substantial savings can comfortably afford rents at higher ratios.

Document your decision-making criteria consistently. Applying a 3x rule to one applicant but waiving it for another is the kind of inconsistency that can attract Human Rights Tribunal scrutiny.

Credit check interpretation

A credit score is one data point. A 720+ score with a thin file is worse than a 660 score with a long, clean payment history. Look for: payment history, total debt load, recent credit-seeking behaviour, and any collections or bankruptcies.

Don't reject based on score alone. Combine credit data with income verification and references to form a holistic picture.

Reference checks that work

Prior-landlord references are the most valuable single data source. Useful questions:

• Was rent paid on time and in full each month?
• Were there any complaints from neighbours or the building?
• Were there any property damage issues at move-out?
• Would you rent to this tenant again?
• Was the proper notice given when they left?

Standardized rejection letters

When you reject an application, send a brief written rejection that doesn't speculate about the applicant's protected characteristics. Standard language: 'Thank you for your application. After review, we are not able to proceed with your tenancy at this time.' Document your decision criteria internally.

If asked for reasons, you can specify objective criteria (income below 3x, recent collections on credit report, negative reference) without elaborating beyond what's true and verifiable.

How CentreKey screens

Every CentreKey applicant goes through: multi-bureau credit and identity verification, employment and income verification, prior-landlord references with reference scoring, and a structured interview during showing. Decision criteria are consistent across applicants and documented for every rejection.
