A tenant's accommodation request isn't optional paperwork. It triggers a legal duty with its own standard, its own limits, and its own rules about what a landlord can ask for and what has to happen to that information afterward.
Key takeaways
An accommodation request usually arrives without a form attached — a note about a mobility issue that needs a different unit, a request for a service animal despite a no-pets clause, a scheduling change around a religious observance. Ontario law treats all of it the same way: as a trigger for a specific legal process, not a favour a landlord can grant or refuse at will.
The Ontario Human Rights Commission's policy on rental housing states the obligation plainly: “Landlords have a legal duty to accommodate tenants when legitimate concerns arise based on Code grounds.” The list of grounds is broad — disability, family and marital status, creed, sex, sexual orientation, age (including tenants 16 and 17 who no longer live with their parents), and receipt of public assistance are all named, along with association with someone identified on one of those grounds. And accommodation isn't limited to physical changes: the same policy is explicit that “not all accommodations involve physical facilities — some tenants may need changes to rules and practices to accommodate changing family situations or religious practices.”
The OHRC frames accommodation as joint work, not a one-sided demand: “both the housing provider and the tenant … have a shared responsibility to cooperate in the process, each to the best of their ability. This might involve providing relevant medical or other personal information.” That's the point where the accommodation duty and privacy law meet, and the OHRC doesn't leave it implicit — the same policy states that “a housing provider has a duty to keep this information private.” A landlord who is entitled to ask a tenant for supporting medical information is not entitled to discuss it with other tenants, staff who don't need it, or anyone else outside the accommodation process.
Federal privacy law backs that duty with its own machinery. PIPEDA applies in provinces without their own substantially similar private-sector privacy law — British Columbia, Alberta and Quebec have their own; Ontario landlords fall under the federal regime. It requires the landlord to identify the purpose for collecting personal information before or at the time of collection, limit collection to what a reasonable person would consider appropriate for that purpose, obtain consent (express consent for sensitive information of exactly this kind), and give the tenant written access to what's held about them — typically within 30 days of a request. In practice: ask for what the accommodation actually requires, keep it separate from the general tenant file, and don't collect more than the request needs to be assessed.
Undue hardship is a real limit, but it is narrower than landlords often assume. The OHRC ties it to cost or the health and safety of the living environment, and adds a rule that catches most attempts to treat hardship as a full exemption: “when the best possible accommodation would cause undue hardship, there is still a duty to put in interim or next-best solutions.” A landlord who can't provide exactly what was asked for isn't excused from providing anything — the duty shifts to what's achievable short of that hardship, not to nothing.
Timing follows the same logic as everything else in this policy: no fixed number of days, but a real standard. “Whatever steps are decided on, landlords need to put the accommodation in place as quickly as possible.” That's a meaningfully different clock than the one governing a repair request under the maintenance provisions, where the LTB weighs the seriousness of the disrepair and contractor availability — here, urgency is judged against the tenant's actual need, not against a landlord's ordinary maintenance queue.
The same regulatory framework governs what can be asked before a tenancy even starts. Under Regulation 290/98, income information can only be requested alongside — not instead of — rental history and credit information, and a landlord can't apply a rent-to-income cutoff. An accommodation request that surfaces during the application stage sits inside that same non-discrimination frame: refusing an applicant, or treating one differently, because a disclosed accommodation need signals a Code ground is exactly the conduct the tenant-selection rules and the accommodation duty both exist to prevent. And whatever medical or disability-related detail comes with the request is subject to the same PIPEDA consent and purpose-limitation rules as any other personal information a landlord collects — including, later, whatever gets collected to verify a tenant's own insurance if the tenancy agreement requires it.
A tenant with a mobility disability requests a reserved parking spot near the building's accessible entrance, supported by a note from a healthcare provider. The building has no reserved spots at all — parking is unassigned, first-come. Converting one spot to reserved and accessible costs the landlord nothing structural, but it does mean the tenant currently parking closest to the entrance most mornings loses that convenience.
That is not undue hardship in the OHRC's sense — the loss falls on another tenant's convenience, not on the landlord's cost or the building's health and safety. The landlord designates the spot, keeps the medical note in a file separate from the general tenancy file, and does not disclose the reason for the change to the tenant who lost first-come access to that space. Now vary the facts: the request is for a spot directly outside a unit where none exists structurally without demolishing a retaining wall. That likely does cross into cost-based undue hardship — but the duty to accommodate doesn't end there. The next-best option, the closest available accessible spot with a shortened, level path to the entrance, still has to be offered and implemented as quickly as possible.
Yes — the OHRC frames the process as shared responsibility, which can include providing relevant medical or other personal information. What the landlord can't do is ask for more than the request needs to be assessed, or use that information for anything beyond the accommodation itself, and it has to be kept private once received.
No fixed number of days is set out in the OHRC's policy. The standard is that the accommodation be put in place as quickly as possible once the need and the appropriate response are established — a materially different standard than the reasonable-time test used for ordinary repair requests.
Undue hardship is a real defence, but it isn't a full exemption. Even where the ideal accommodation would cause undue hardship in terms of cost or health and safety, the landlord still has to provide the best available interim or next-best solution short of that hardship.
As few people as the process requires. The duty to keep the underlying information private sits directly alongside the duty to accommodate — discussing a tenant's medical or disability information with other tenants, or with staff who don't need it to implement the accommodation, is itself a breach of the same policy.
