Modified duties in Ontario are changes to your normal job that allow you to work safely within medical restrictions or disability-related limitations.

If modified duties are needed to accommodate a disability, your employer must seriously consider them and provide appropriate accommodation unless doing so would cause undue hardship. Modified work can include lighter tasks, different hours, additional breaks, temporary reassignment or changes to how your regular job is performed.

But you do not have an automatic right to choose any modified job you want, and your employer cannot simply invent “light duties” that conflict with your medical restrictions. Accommodation is an individualized, cooperative process focused on what you can safely and reasonably do.

⚠️ If proposed modified duties conflict with your medical restrictions, don’t simply refuse the work or stop attending. Put your concerns in writing, obtain updated medical information where needed and get advice about the safest next step. An outright refusal of reasonable accommodated work can affect your rights.

What Are Modified Duties in Ontario?

Modified duties are temporary or longer-term changes to your work that allow you to perform your job within legitimate medical restrictions or other accommodation needs.

They are commonly used when an employee is returning after an injury, surgery, illness, disability leave or another medical absence.

Examples of modified duties include:

  • Removing or reducing heavy lifting
  • Providing seated work instead of prolonged standing
  • Reducing repetitive movements
  • Changing driving, travel or physical requirements
  • Reducing hours or providing shorter shifts
  • Providing additional rest breaks
  • Allowing time for medical appointments or treatment
  • Temporarily removing safety-sensitive duties
  • Reducing competing deadlines or other cognitive demands
  • Allowing remote or hybrid work where it appropriately addresses the limitation
  • Temporarily assigning other suitable work

Ontario human rights guidance specifically recognizes modified job duties, flexible schedules and alternative work as possible forms of disability accommodation.

💡 “Modified duties” does not mean your employer gets to decide what looks easy. The duties have to be assessed against your actual functional abilities and restrictions.

Does an Employer Have to Provide Modified Duties in Ontario?

Yes, when modified duties are an appropriate way to accommodate a disability and they can be provided without undue hardship.

Ontario’s Human Rights Code requires employers to accommodate disability-related needs so that employees who are capable of working can participate in the workplace. An employer cannot simply insist that you perform your job exactly as before if reasonable changes would allow you to work safely.

The employer should consider your individual circumstances and explore practical solutions rather than relying on a blanket rule.

That can mean changing:

  • Particular job tasks
  • Your work schedule
  • How or where duties are performed
  • Equipment or workstation setup
  • The pace or sequencing of work
  • Your return-to-work schedule

Read our complete guide to the duty to accommodate in Ontario.

Does your employer have to create a completely new job?

Not necessarily. Accommodation does not require an employer to permanently eliminate the genuine essential requirements of a job or create meaningless work solely to keep someone occupied.

However, the employer must genuinely examine whether duties can be changed, non-essential tasks can be reassigned or suitable alternative work is available before concluding that accommodation is impossible.

What does undue hardship mean?

Undue hardship is a high legal threshold. Ordinary inconvenience is not enough.

Under Ontario’s Human Rights Code, the relevant undue-hardship considerations are:

  • Cost
  • Available outside sources of funding
  • Health and safety requirements

Some hardship is expected. The obligation ends only when the hardship becomes undue.

See our deeper guide to undue hardship in Ontario.

What Medical Information Do You Need for Modified Duties?

Your medical information should explain your functional restrictions and limitations so your employer can determine what work you can safely perform.

Useful medical information can include:

  • How much you can lift, carry, push or pull
  • Limits on standing, sitting, walking or driving
  • Restrictions involving repetitive movement
  • Limits involving concentration, memory or cognitive workload
  • Whether you need reduced hours or extra breaks
  • Whether particular environments or safety-sensitive tasks should be avoided
  • How long the restrictions are expected to remain
  • When your abilities should be reassessed

Your employer is entitled to enough relevant information to understand and respond to your accommodation needs. It is not automatically entitled to your complete medical file or detailed diagnosis. Ontario human rights guidance emphasizes functional restrictions and the information reasonably necessary to provide accommodation.

💡 A vague note saying “light duties” can create problems. Medical documentation is more useful when it explains what you can and cannot safely do.

Can your employer ask for updated medical information?

Yes. If your condition changes or restrictions are expected to be temporary, reasonable medical updates can be required so the accommodation remains appropriate.

Accommodation is an ongoing process. As your abilities improve or change, your duties can be reassessed rather than remaining frozen indefinitely.

Can You Refuse Modified Duties in Ontario?

You can challenge modified duties that are unsafe or inconsistent with your medical restrictions, but you should not simply refuse reasonable accommodated work without addressing the problem.

The accommodation process is a shared responsibility. Employees are expected to communicate their restrictions, provide appropriate supporting information and participate in finding a workable solution.

For example, raise the issue immediately if:

  • Your doctor says no lifting over 10 pounds but the modified job requires heavier lifting
  • Your restrictions require four-hour shifts but you are scheduled for eight hours
  • A supposedly “light” job still requires the movement your medical provider prohibited
  • The duties worsen your symptoms or create a genuine safety concern

Explain the specific conflict in writing and ask that the duties be reviewed against your restrictions. If your medical condition has changed, get updated documentation.

⚠️ Don’t walk off the job or refuse all modified work because you dislike the assignment. If the accommodation is medically appropriate and reasonable, refusing to cooperate can weaken your legal position.

Can your employer force you back before you are medically ready?

No. Your employer cannot simply disregard valid medical restrictions and require you to perform work that exceeds your demonstrated abilities.

At the same time, being unable to perform your full regular job does not automatically mean you must remain completely off work. If you can safely perform accommodated work, a return on modified duties can be appropriate.

If you are returning after a disability leave, see our guide to returning to work after short-term disability in Ontario.

What Happens to Your Pay and How Long Can Modified Duties Last?

Modified duties do not automatically mean that your employer can cut your pay, and there is no single legal time limit for how long accommodation can last.

Can your pay be reduced on modified duties?

A disability does not give your employer a free-standing right to reduce your wages.

If you continue working your regular hours with adjusted duties, a pay reduction tied to assumptions about your disability can raise serious concerns. Ontario human rights authorities have found discrimination where an employer placed an employee in lower-paid, part-time work despite medical clearance supporting greater work capacity.

The situation is different if your medical restrictions legitimately reduce the hours you are able to work. Income-replacement benefits can also matter.

⚠️ Don’t agree to a permanent pay reduction, demotion or loss of status simply because your employer calls it “modified work.” A substantial unwanted change can raise discrimination or constructive dismissal issues.

How long can modified duties last?

Modified duties can last as long as they remain medically required and form part of an appropriate accommodation arrangement.

Some employees need modified duties for only a few weeks. Others have permanent limitations that require longer-term accommodation.

The arrangement should be reviewed as your medical abilities change. Temporary alternative work can be appropriate during recovery, while permanent alternative work can also require consideration where an employee can no longer perform the original position and appropriate work is available.

Do you have the right to return to your regular job?

If you become medically capable of performing your original job, returning to that position is normally the goal rather than leaving you indefinitely in unnecessary modified work.

Ontario human rights guidance recognizes that employees returning from disability-related absences generally have the right to return to their pre-disability job, subject to the individual accommodation analysis and undue hardship.

What If Your Employer Refuses Modified Duties or Ignores Your Restrictions?

An employer that refuses reasonable disability accommodation without establishing undue hardship can violate Ontario’s Human Rights Code.

Warning signs include:

  • Refusing to discuss accommodation at all
  • Insisting you must be “100% recovered” before returning
  • Ignoring clear medical restrictions
  • Providing duties that repeatedly exceed your limitations
  • Punishing you for requesting accommodation
  • Cutting your hours or opportunities because of assumptions about your disability
  • Pressuring you to resign instead of considering workable accommodation
  • Firing you because you require modified duties or medical accommodation

Can refusing accommodation amount to constructive dismissal?

Yes, a serious failure to accommodate can contribute to a constructive dismissal claim when the employer’s conduct fundamentally changes or undermines the employment relationship.

A major pay reduction, demotion or other fundamental change imposed instead of properly addressing your disability can also raise constructive dismissal concerns.

⚠️ Don’t resign because your employer refuses accommodation before getting legal advice. Whether the situation amounts to constructive dismissal is fact-specific, and resigning too early can jeopardize severance rights.

Modified Duties Ontario: Frequently Asked Questions

What is considered modified duty in Ontario?

Modified duty is work that has been adjusted so you can perform it within your functional abilities or medical restrictions. It can include lighter physical tasks, reduced hours, extra breaks, altered schedules, different duties or another suitable temporary assignment.

Does my employer have to follow my doctor’s restrictions?

Your employer must take legitimate medical restrictions seriously and use them when assessing appropriate accommodation. The employer can seek reasonable clarification when necessary, but it should not simply substitute its own non-medical assumptions for medical evidence.

Can I stay off work instead of accepting modified duties?

Not simply because you would prefer to remain off work. If you are medically able to perform reasonable accommodated duties, you are expected to participate in the accommodation process. If the duties are unsafe or inconsistent with your restrictions, raise the specific problem and obtain medical support rather than refusing without explanation.

Can modified duties be permanent?

Yes. A permanent disability can require ongoing accommodation. Whether a particular modification must remain permanently depends on the employee’s restrictions, the essential requirements of the job, available alternatives and whether the accommodation would cause undue hardship.

Can my employer fire me because I need modified duties?

Your employer cannot lawfully fire you because of a disability without first meeting its human-rights obligations. If you can perform the essential duties with accommodation, the employer must accommodate you to the point of undue hardship.

What if my employer gives me meaningless or humiliating “light duties”?

Accommodation must respect dignity and be individualized. Modified work should address your actual limitations rather than isolate, stigmatize or unnecessarily diminish you. Raise the problem in writing if an assignment appears designed without regard to your real abilities or workplace role.

⚠️ Unionized? Modified-duty and accommodation disputes must be addressed through your union and the grievance process. Our employment law team can’t assist with unionized workplace disputes.

Modified duties should help you work safely—not force you to choose between ignoring your medical restrictions and losing your job. Your employer must genuinely consider reasonable accommodation, and you must participate in that process in good faith.

If your employer is ignoring your restrictions, refusing accommodation, cutting your pay or pressuring you to resign, get advice from Samfiru Tumarkin LLP before making a permanent decision about your employment.

Employer Ignoring Your Medical Restrictions?

Don’t resign, refuse work outright or accept unsafe duties before you understand your accommodation rights.
