Key takeaways
  • A landlord may ask for credit references, rental history and permission for a credit check, and may use them to select or refuse an applicant.
  • The only deposit allowed is a rent deposit of no more than one month's rent (or one rent period if that is less), and post-dated cheques cannot be required.
  • Everyone has a right to equal treatment in renting, and lease terms that conflict with the Residential Tenancies Act, 2006 are void.

If you are a landlord choosing a tenant, or an applicant wondering whether a request is fair, the rules in Ontario are narrower than many people expect. Some questions are allowed, some are allowed only in combination, and some are not allowed at all.

This guide walks through what a landlord may ask for, what they may require, and where the Human Rights Code and the Residential Tenancies Act, 2006 (RTA) set limits. It is general information, not advice on a particular situation.

Credit, rental history and income information

A landlord may ask a prospective tenant for credit references and rental history, and for permission to run a credit check. The landlord may use these to select or refuse the applicant.

Income information is treated differently. A landlord may ask for it only if they also ask for credit references, rental history or a credit check, and it must be considered together with that other information.

There is an exception. If the landlord asked for all of the listed information but obtained only income information, the landlord may consider income alone.

Guarantors, deposits and post-dated cheques

A landlord may require a prospective tenant to get a guarantee for the rent, so guarantor clauses are permitted. A guarantor who is named as a tenant in the lease but has no right to occupy the unit does not become a tenant under the RTA. How far a guarantor is responsible depends on the wording of the guarantee, so it is worth reading carefully before signing.

A security deposit may be required only in line with the RTA. The only deposit a landlord may collect is a rent deposit.

Human Rights Code limits

Everyone has a right to equal treatment in the occupancy of accommodation, without discrimination because of the following grounds.

Using income information, credit checks, credit references, rental history or guarantees in the manner the regulation prescribes does not infringe the Code. Using them outside those rules can raise a problem.

Exceptions worth knowing

SituationWhat the rule says
Shared kitchen or bathroom with the ownerThe Code's accommodation right is not infringed where the occupant must share a bathroom or kitchen with the owner or the owner's family, in a dwelling where they live. The RTA also does not apply in that case.
Self-contained basement apartmentIt does not fall under the RTA shared-space exemption.
Aged 16 or 17A 16- or 17-year-old who has withdrawn from parental control has a right to equal treatment in renting, and a lease they sign is enforceable against them as if they were 18.

Leases and what to do next

For most private rentals, landlords must use the Ontario standard lease for new leases. If a tenant asks in writing and does not receive it within 21 days, the tenant may withhold one month's rent. The RTA applies despite any agreement or waiver to the contrary, and any lease term that conflicts with the Act is void.

Frequently asked questions

Can a landlord ask for my income?

Yes, but only if they also ask for credit references, rental history or a credit check, and they must consider income together with that information. If they asked for everything but got only income information, they may consider income alone.

Can a landlord require a guarantor?

Yes, a landlord may require a prospective tenant to get a guarantee for the rent. A guarantor named in the lease who has no right to occupy the unit does not become a tenant under the RTA.

How much deposit can a landlord take?

Only a rent deposit is allowed, and it can be no more than one rent period or one month's rent, whichever is less. It earns annual interest at the rent increase guideline rate.

Can a landlord ask for post-dated cheques?

No. Neither a landlord nor a lease may require a tenant or prospective tenant to provide post-dated cheques or other negotiable instruments for rent.
