The 3x Rent Myth: Income Cut-Offs Are Not a Screening Rule

The belief

The rule sounds like underwriting. An applicant should earn roughly three times the monthly rent, or spend no more than 30 per cent of gross income on it. Clear the line and you get a showing. Fall under it and you get a polite no. It fits on a sticky note, every leasing agent can apply it, and it feels like risk management.

In Ontario it is against the law. The Ontario Human Rights Commission puts it in one sentence in its guide for landlords: unless you are providing subsidized housing, it is illegal to apply a rent-to-income ratio such as a 30 per cent cut-off rule.

What you can ask for, and how you have to weigh it

Tenant selection in Ontario is governed by Regulation 290/98 under the Human Rights Code. It is short, and the order of operations inside it is the whole point.

• You may request credit references and rental history, and you may ask for authorization to run a credit check.
• You may consider those three alone or in any combination, and select or refuse on that basis.
• You may request income information only if you also request the items above.
• You may consider income information only together with all the other information you obtained.
• If you asked for everything and income was the only thing that came back, then you may consider income on its own.

A ratio breaks that structure. It does not weigh income alongside credit and references, it converts income into a gate that runs before anything else is read. An applicant with eight years of on-time payments at their last two addresses and a clean credit file never gets assessed, because the arithmetic disqualified them at the pre-screen.

The regulation also lets you require a guarantee for the rent and a deposit taken in accordance with the Residential Tenancies Act. Neither of those is a loophole for the ratio, as covered below.

The ratio does not predict what you think it predicts

This was tested. In Kearney v. Bramalea, three landlords used minimum income criteria, two of them as rent-to-income ratios. The Board of Inquiry found the practice breached the Code whether it was used alone or alongside other criteria, and that it was not a bona fide requirement because it had no value in predicting whether a tenant would default. The Ontario Superior Court upheld the finding on appeal.

The population data says the same thing from a different direction. In the 2021 Census, 33.2 per cent of Canadian renter households spent 30 per cent or more of their income on shelter, rising to 38.4 per cent in Ontario. A 30 per cent cut-off does not filter out risky renters. It filters out about a third of the renting population, most of whom pay their rent in full and on time, and it does so hardest among the groups the Code protects.

The guarantor version of the same mistake

Operators who drop the ratio from the application often keep it on the guarantor. The Commission has flagged this pattern directly: landlords automatically requiring a co-signor from applicants on a low income or on social assistance, then applying a restrictive rent-to-income ratio to that co-signor. Few applicants have access to a guarantor who clears an arbitrary multiple of the rent, so the barrier survives with an extra step in front of it.

You can require a guarantee. The requirement has to be the same for every applicant, not switched on for the ones whose income looks unusual to you.

Where the ratio is allowed

Section 3 of Regulation 290/98 carves out rent-geared-to-income housing. If you are determining eligibility for a unit where rent is set by income, you may request and use income information for that purpose without the weighing requirement. That exception is narrow and it is about eligibility for a subsidy, not about assessing risk in a market unit.

Outside Ontario

Other provinces do not have a regulation that prescribes how income information gets weighed, so the ratio is not addressed head on. The exposure comes from a different direction. In British Columbia, section 10 of the Human Rights Code makes lawful source of income a protected ground in tenancy. In Alberta, source of income is a protected ground under section 5 of the Alberta Human Rights Act. A blanket multiple applied to every applicant lands hardest on people whose income comes from disability benefits, a pension, or assistance, and that is the shape a complaint takes.

What to screen on instead

Everything the ratio was standing in for is available, and most of it is a better signal.

• Payment history from rental references. Ask the previous landlord for dates and amounts, not a character reference. Whether rent arrived on the first of the month for 24 months tells you more than any multiple of income.
• The credit file, read for pattern. You are looking for a history of default, not a score threshold. A thin file is not a bad file, and the Commission is explicit that a lack of rental or credit history should not be viewed negatively. That matters for newcomers, students and young renters.
• Income sufficient to cover the rent. Confirming that the money is there is permitted. Setting a multiple is not. The question is whether the applicant can pay the rent, not what share of their budget it represents.
• The same criteria for everyone. Written down, applied in the same order, with the reason for each decline recorded against them.

How to fix it this week

1. Find every place the ratio is written down. It hides in the application form, the ad copy, the agent script, the portal listing text, and the rule set inside your screening software.
2. Replace it with a sufficiency check on income that is read alongside credit and rental history, in that order.
3. Make the guarantor requirement uniform or remove it.
4. Record a reason for every decline, tied to your written criteria. If the only reason you can name is the ratio, you did not have a reason.
5. Brief whoever speaks to the applicant first. The cut-off usually outlives the policy change by months because it lives in a pre-qualifying question asked over the phone.

The ratio feels like a risk control. It works like an availability filter, screening out renters who would have paid while telling you nothing about the ones who will not. The information that does predict default is already in your application file, and the law asks you to read it.
