You asked for a change at work because of a disability, a medical condition, your religion, a pregnancy, or a caregiving obligation, and the answer was no. Or there was no answer at all, which in law can amount to the same thing. A refusal is not the end of the matter, and in Ontario it is frequently the point at which the employer, rather than the employee, has a problem.
Updated September 2026
This article covers what your employer is actually required to do, the three reasons it is allowed to say no and the many it is not, what the courts have said an employer has to prove before it can rely on undue hardship, what you have to do in return, and the steps that protect your position after a denial.
Inconvenience, cost to morale, what other staff might think, and the employer’s general preference are not part of the test. Neither is a blanket policy applied without looking at your situation. Many denials fail on the process rather than on the merits, because the employer never genuinely considered the request.
What counts as accommodation
Accommodation is any change to rules, duties, schedules, equipment, or environment that removes a barrier connected to a protected ground. In employment that usually means modified duties, a changed schedule or shift pattern, remote or hybrid work where the role permits, a graduated return after a medical leave, assistive equipment, or scheduling around religious observance.
The protected grounds most often engaged at work are disability, which includes mental health conditions, creed, family status, pregnancy, gender identity, and age. Our article on the Ontario Human Rights Code at work sets out the full list. In British Columbia the equivalent list is covered in our article on protected grounds under the BC Human Rights Code.
The three factors, and everything that is not one
Undue hardship is a legal test with a closed list. Only three things count.
Cost
The financial burden, assessed against the size and resources of the whole organisation rather than one department or branch budget.
Outside sources of funding
Whether grants, programs, or other funding are available to offset the cost, which the employer is expected to look into.
Health and safety
A genuine, evidenced risk, weighed against the risk the workplace already tolerates. A general worry is not evidence.
Anything else an employer offers as a reason is outside the test. Business inconvenience, disruption to scheduling, the reaction of co-workers, customer preference, a collective agreement term, and the fact that nobody else gets that arrangement are all, on their own, not undue hardship.
What the employer actually has to prove
Undue hardship is a defence, and the burden of establishing it sits with the employer. Asserting it is not the same as proving it, and three decisions set the bar.
Put together, these give you the questions to ask about any refusal. What standard is being applied and why. What was actually considered and rejected. What evidence exists for the cost or the safety risk being claimed. An employer that cannot answer those has asserted undue hardship rather than established it.
Where denials usually go wrong
No individual assessment
A policy applied across the board without looking at your circumstances. Accommodation is individual by definition.
No exploration of options
The employer rejected what you asked for without considering whether something else would work. The duty is to explore, not to answer yes or no.
Assertion instead of evidence
Undue hardship claimed without figures, risk assessment, or any analysis behind it.
Silence and delay
No fixed deadline exists, but an unreasonable delay can itself be a failure to accommodate. A request that goes unanswered for months is a denial in practice.
The grounds this comes up on most
The duty is the same whatever the ground, but the arguments differ.
Age. Ontario has no general mandatory retirement age, and a policy requiring people to retire at a fixed age is age discrimination unless the employer can meet the Meiorin standard. Our article on mandatory retirement in Ontario sets out the narrow exceptions.
Record of offences. Ontario is unusual in protecting this in employment, so a blanket refusal to hire or retain someone with a record is not automatically lawful. Our article on being fired for having a criminal record covers what the ground does and does not reach.
Conduct that is cumulative rather than single incident. Where the problem is a pattern of small slights rather than one event, the analysis is about the overall environment. Our article on microaggressions in the workplace explains how those are assessed.
Probationary and short service employees. The Human Rights Code applies from the first day, so probation does not remove the duty to accommodate, although it does change what an employer must show on dismissal. Our note on an arbitrator upholding a probationary termination shows how those two things sit together.
What you have to do in return
This is the part that is missing from most articles on the subject, and it is where employees most often damage their own position.
Accommodation is a shared process. You are expected to make the need known, provide enough information to establish it, cooperate with reasonable requests for clarification, and engage with what is offered. If you decline a workable accommodation because it is not the one you asked for, the employer’s duty can be treated as discharged.
You are entitled to reasonable accommodation, not to your preferred accommodation. That distinction decides a significant number of these cases. If what is offered does not actually work, the answer is to say so in writing and explain why, not to refuse it flatly or simply stop engaging.
What medical information you have to provide
Enough to establish the need and the limitations, and generally no more. An employer is entitled to know what you can and cannot do, how long the restrictions are expected to last, and what accommodation the practitioner supports. It is not automatically entitled to your diagnosis, your treatment, your medication, or your clinical records.
Requests that go well beyond function are common and are worth pushing back on in writing rather than complying with by reflex. Our articles on whether you have to disclose medical information to your employer and on doctors’ notes and workplace accommodations cover what a note should and should not say.
Family status is a special case in Ontario
If your request concerns childcare or eldercare, be careful with what you read. Much of the material online sets out a federal four-part test that Ontario does not use. The Human Rights Tribunal of Ontario applies the ordinary discrimination test instead, which is generally a lower bar for the employee than the federal approach. Our article on family status discrimination sets out the Ontario position.
What to do after a denial
Ask for the reasons in writing
Ask specifically which factor the employer relies on and what it considered. A denial that cannot be explained in writing is usually a denial that was never properly assessed, and the reply becomes evidence either way.
Check the employer’s own policy
Most organisations have an accommodation policy setting out how requests are handled. Where the employer did not follow its own process, that is one of the strongest points available to you.
Propose an alternative in writing
Offering another workable option keeps the process alive, shows you have met your side of the duty, and makes a later refusal harder for the employer to defend.
Keep the file
The original request, the medical documentation, every message about it, notes of meetings with dates and names, and the policy itself. Contemporaneous records carry far more weight than an account assembled months later.
Get advice before you resign or escalate
The routes available differ in what they award and how long you have. Choosing one can close another, and the shortest deadline is shorter than most people expect.
The bigger claim behind the denial
A refused accommodation is often treated as a standalone complaint when it is really the first step in something larger, and the larger thing is usually worth more.
Where the refusal makes the job impossible to keep, or where duties, hours, or pay are cut because you cannot perform the unmodified role, that can amount to constructive dismissal, which carries a notice entitlement on top of any human rights remedy. Where you are disciplined or dismissed after raising the request, that is capable of being reprisal, which is a separate breach with its own remedies.
Where the situation involves a medical leave and an insurer as well as an employer, there are two disputes running at once and they are frequently confused with each other. Our article on medical accommodation compared with long term disability explains which is which.
Filing at the tribunal
Where accommodation has been refused without proper justification, an application to the Human Rights Tribunal of Ontario is the usual route. Remedies include compensation for lost income, damages for injury to dignity, feelings and self-respect, reinstatement, and orders directed at the employer’s future conduct such as policy changes and training.
Our article on what the Human Rights Tribunal of Ontario decides covers what belongs there and how the forum choice affects the value of the claim, and our article on limitation periods sets out the deadlines that apply to each route.
Before you do anything else
- Put the request in writing if it was verbal, and keep a copy.
- Ask for the denial and its reasons in writing.
- Note the date of the refusal, because the one-year clock runs from the last incident.
- Find the employer’s accommodation policy and check what it required.
- Keep medical documentation to function and limitations, not diagnosis.
- Propose an alternative rather than refusing outright.
- Do not resign in frustration before the claim has been valued.
Frequently asked questions
Can my employer deny my accommodation request?
Only where providing it would cause undue hardship, assessed on cost, outside sources of funding, and health and safety. Inconvenience, business preference, and the reaction of other staff are not part of the test, and a refusal that relies on them is likely to fail.
Who has to prove undue hardship?
The employer. It is a defence, and the employer carries the burden of establishing it with evidence rather than assertion. Under the Meiorin analysis the employer must show that the standard was rationally connected to the job, adopted in good faith, and reasonably necessary, which means demonstrating that the individual could not have been accommodated short of undue hardship.
Is a collective agreement a defence to a failure to accommodate?
Generally no. In Central Okanagan School District No. 23 v. Renaud, the Supreme Court held that a term in a collective agreement does not excuse a failure to accommodate, and that objections from co-workers carry little weight unless the effect on them is genuinely substantial.
How long does an employer have to respond to a request?
There is no fixed deadline in the Human Rights Code, but an employer is expected to respond promptly and to engage in the process in good faith. An unreasonable delay can itself be a failure to accommodate, so a request left unanswered is not a neutral outcome.
Do I have to accept the accommodation my employer offers?
You are entitled to a reasonable accommodation, not to the one you preferred. If a workable option is offered and you refuse it, the employer’s duty may be treated as met. If the option does not actually address the barrier, say so in writing and explain why rather than refusing outright.
Does the duty to accommodate ever end?
Yes. In Hydro-Quebec, 2008 SCC 43, the Supreme Court held that the standard is not impossibility, that an employer is not required to fundamentally alter the working conditions, and that where the evidence shows the employee will be unable to work in the reasonably foreseeable future despite accommodation, the duty has been discharged. The assessment is made over the whole period rather than on a single day.
How much medical information can my employer ask for?
Enough to establish the need and your functional limitations, how long they are expected to last, and what accommodation is supported. A diagnosis, treatment details, and clinical records are generally not required, and a request for them is worth questioning in writing.
Can my employer deny time off for religious observance?
Not without justification. Creed is a protected ground, and the employer must make genuine efforts to accommodate observance unless doing so reaches undue hardship on the three-factor test. Scheduling difficulty on its own does not meet it.
What can the tribunal order if my employer failed to accommodate?
Compensation for lost income, damages for injury to dignity, feelings and self-respect, reinstatement in some cases, and orders directed at the employer’s future conduct, such as policy changes and training.
Can I be fired for asking for an accommodation?
Dismissal or discipline connected to an accommodation request is capable of being reprisal, which is a separate breach of the Human Rights Code. Where the refusal made the job impossible to keep, it can also support a constructive dismissal claim carrying a notice entitlement.
How Achkar Law helps
We advise employees whose accommodation requests have been refused, delayed, or handled without any real assessment. That means working out whether the employer met its obligations, what the file needs to look like, whether the situation has already become a dismissal claim as well as a human rights one, and which route recovers most.
See our human rights lawyers, our constructive dismissal lawyers where the role has become impossible to hold, and our long term disability claims practice where an insurer is also involved. In the GTA, see our Toronto human rights lawyers.
This article is general information about Ontario employment and human rights law and is not legal advice. The law described is current as of September 2026. Whether an employer has met the duty to accommodate depends on the full circumstances, and deadlines are short. An employment lawyer can advise on your specific situation.
