Short answer: in Ontario you can legally screen a tenant, but only within two hard limits. First, PIPEDA generally requires the applicant’s consent before you run a background check. Second, the Ontario Human Rights Code prohibits basing any screening decision on a protected ground such as race, religion, family or marital status, disability, or receipt of public assistance. Inside those limits you can verify identity and documents, run a credit check, search civil-litigation and Landlord and Tenant Board history, and confirm rental history and references, as long as you verify references rather than taking them at face value. That verification step is where careless landlords get caught by “professional tenants,” and where a consolidated, lawfully gathered report earns its keep.
This is the compliance-focused companion to our overview of how we help landlords day to day: Tenant Troubles? How Private Solutions Investigators Assist Landlords. If you want the “how screening actually works” version, start there; this piece is about doing it legally.
What can a landlord legally check in Ontario?
With proper consent, and applied consistently to every applicant, you can verify a lot. And you should, because a tenancy is a significant financial relationship.
- Identity and document verification. Confirm the applicant is who they say they are, and that the ID and paystubs they’ve provided are genuine and current, not templates downloaded and edited.
- Credit history. A credit check (with consent) shows how someone handles financial obligations. It’s a legitimate, relevant signal.
- Civil litigation and Landlord and Tenant Board (LTB) history. Prior LTB proceedings and civil judgments can reveal a pattern; for instance, repeated non-payment applications against the applicant.
- Reference verification. Not “collect references,” but verify them: confirm the reference is a real, prior landlord and not a friend with a script.
- Rental-history confirmation. Contact past landlords to confirm tenancy dates, payment behaviour, and condition of the unit.
- Criminal record check, where appropriate and with consent, applied consistently.
The governing framework here is the Residential Tenancies Act (RTA) and the LTB, and it’s worth remembering that once someone becomes your tenant, those rules strongly constrain what you can do. That’s exactly why the screening stage, the one moment you have the most freedom and the most leverage, deserves rigour.
What does the Ontario Human Rights Code prohibit?
This is the limit that catches good-faith landlords off guard, so it’s worth being precise. The Ontario Human Rights Code prohibits screening decisions based on protected grounds. In housing, those grounds include:
- race, ancestry, colour, place of origin, ethnic origin, citizenship;
- creed (religion);
- sex, sexual orientation, gender identity, gender expression;
- age;
- disability;
- family status and marital status (including having children, or being a single parent);
- receipt of public assistance.
That last pair trips people up. You cannot refuse an applicant because they have kids, because they’re a single parent, or because part of their income comes from social assistance. You also can’t use a facially neutral rule (like a rigid rent-to-income ratio) to screen out people on assistance in a way that has a discriminatory effect.
What you can do is assess a candidate’s genuine ability to meet the tenancy using legitimate criteria (income, credit, references, rental history) applied the same way to everyone. The safest posture is consistency: the same checks, the same questions, the same standards for every applicant, documented. Consistency is both good ethics and your best evidence if a decision is ever challenged.
What consent does PIPEDA require before a background check?
Under the Personal Information Protection and Electronic Documents Act (PIPEDA), you generally need the applicant’s consent before collecting and checking their personal information, and consent for a credit check in particular. In practice that means a clear, written authorization that states what you intend to check (identity, credit, references, LTB/civil records, criminal record) before you run anything.
Two things landlords underestimate about consent:
- It’s a compliance requirement, not a formality. Running a credit or background check without consent puts you offside PIPEDA and credit-reporting rules, and any decision built on improperly obtained information is a liability, not an asset.
- It’s also a filter. Applicants acting in good faith sign a clear consent form without drama. Applicants who bristle at being checked, stall, or suddenly withdraw are telling you something useful before you’ve spent a dollar.

How do I spot a “professional tenant”?
“Professional tenant” isn’t a slur for someone who’s struggling. It describes a specific bad-faith actor who has learned to exploit tenant protections: move in, stop paying, and ride LTB timelines to live rent-free for months while an eviction grinds through the process. The RTA rightly protects tenants; a small number of people weaponize it.
The red flags cluster around things that don’t verify:
- Reluctance to consent to checks, or pushing to skip them “to save time.”
- References that don’t hold up. The “previous landlord” whose number goes to a friend, who can’t recall basic tenancy details, or who is suspiciously effusive. Verify authenticity: call, ask specifics, and cross-check that the person actually owns the address they claim to have rented out.
- Inflated or unverifiable income. Paystubs that don’t match the employer’s real format, an employer “HR line” that’s a personal cell, income that can’t be corroborated.
- Rental-history gaps or a story that changes when you probe it.
- Pressure and urgency. A push to sign immediately, pay in an unusual way, or move in before checks are done.
One practitioner detail: the single highest-value step in tenant screening is verifying the previous landlord actually exists and actually owned that property. A fabricated glowing reference is the professional tenant’s core tool, and it’s defeated by one property-ownership cross-check that most landlords never think to run. When we screen, that’s a standard step, not an extra.
What about OpenRoom.ca and other tools?
Tools help. They don’t finish the job.
OpenRoom.ca can surface a preliminary rental profile and references and is a reasonable early input; it’s worth checking. But it is not a substitute for verified identity checks, a proper consent-based credit check, LTB and civil-litigation searches, and direct reference confirmation. Treat any single tool as one data point in a picture you still have to assemble and verify. The failure mode we see is a landlord who ran one lookup, saw nothing alarming, and skipped the verification that would have surfaced the fabricated reference.
How does a consolidated PI report reduce risk?
Screening well is time-consuming, and doing it legally adds discipline most landlords don’t have time for: securing proper consent, applying identical criteria to every applicant, verifying rather than trusting, and keeping records that would survive scrutiny.
A licensed investigator’s value is a single, consolidated report built the right way: consent obtained under PIPEDA, protected-ground pitfalls of the Human Rights Code avoided, references verified for authenticity, LTB and civil history searched, income and identity confirmed, and all of it lawfully gathered, which matters enormously if you ever end up in front of the LTB. Evidence for an LTB dispute has to be lawfully obtained to carry weight; a report assembled sloppily or improperly can be worse than none. You get one clear document, defensible criteria applied consistently, and far less exposure to both bad tenants and discrimination complaints.
The Ontario legal context, in one place
To keep the boundaries clear: tenant screening in Ontario sits inside the Residential Tenancies Act and the Landlord and Tenant Board framework. Before running a background check you generally need the applicant’s consent under PIPEDA. You may not base a screening decision on a protected ground under the Ontario Human Rights Code, including race, religion, family status, marital status, disability, or receipt of public assistance. Legitimate checks (identity, credit, LTB/civil history, references, rental history) must be applied consistently and, if they’re ever used in an LTB dispute, must be lawfully gathered to be usable.

Frequently asked questions
Is it legal to run a background check on a tenant in Ontario?
Yes, with consent. Under PIPEDA, you generally need the applicant’s consent before running a background check. With that consent you can lawfully verify identity and documents, check credit history, look at civil litigation and Landlord and Tenant Board records, and confirm rental history with past landlords. What you cannot do is base a decision on a protected ground under the Ontario Human Rights Code.
What can’t I ask or decide on when screening a tenant?
The Ontario Human Rights Code prohibits screening decisions based on protected grounds, including race, ancestry, place of origin, religion, sex, sexual orientation, age, disability, family or marital status, and receipt of public assistance. You can assess a person’s ability to meet the tenancy on legitimate, consistently applied criteria, but you cannot refuse someone because they have children, receive support, or belong to a protected group.
Can I require a credit check without the applicant’s permission?
No. Running a credit check or other background check without consent conflicts with PIPEDA and, in the case of credit, with credit-reporting rules. Best practice is a written consent that clearly states what will be checked. That consent both keeps you compliant and signals to applicants that you screen seriously, which itself deters bad-faith applicants.
What is a “professional tenant” and how do I spot one?
A professional tenant knows how to exploit tenant protections: moving in, withholding rent, and using Landlord and Tenant Board timelines to stay for months. Warning signs include reluctance to consent to checks, fabricated or unverifiable references, inflated or unverifiable income, and a rental history with gaps or “landlords” who are actually friends. Verifying references for authenticity, not just reading them, is how you catch it.
Is OpenRoom.ca enough to screen a tenant?
It’s a useful starting point, not a full solution. OpenRoom.ca can surface a preliminary rental profile and references, but it isn’t a substitute for verified identity checks, a proper credit check, LTB and civil-litigation searches, and direct reference confirmation. Treat it as one input into a consolidated, lawfully gathered screening, not the whole picture.
