Disability accommodation at work: understanding the process

Accommodation starts with a work-related need. I explain the process, medical information and responsibilities on both sides.

Start with the barrier to doing your work

An accommodation request should explain which part of work has become difficult. This could involve a task, schedule or feature of the workplace. It may concern how a duty is performed. I would start with the work-related need, rather than your full medical history.

Ontario’s Human Rights Code protects a broad range of disabilities. These include invisible, episodic and mental health conditions. A condition does not have to be apparent to a colleague. The issue is how a disability-related need affects your work.

Accommodation is a process with responsibilities on both sides

Employers must accommodate disability-related needs to the point of undue hardship. Adjustments may involve hours, equipment, duties or the working environment. The appropriate response depends on individual needs and the essential requirements of the job.

Employees also have responsibilities. Explain the need, provide reasonably necessary supporting information and help explore workable options. The Ontario Human Rights Commission’s guidance explains these shared responsibilities.

A reasonable, effective option may not be your preferred option. A refusal should not end the discussion without considering the need and available alternatives. Focus on whether an adjustment addresses the barrier. Neither side is automatically entitled to its first choice.

Medical information should relate to the accommodation

The usual focus is on functional limitations and workplace needs. Relevant information may include duties you can perform, restrictions, likely duration and possible adjustments. It may also include when a reassessment is needed. This does not automatically require a diagnosis.

Further information may be justified if the needs are complex or unclear. An employer is not always barred from asking for diagnostic information. Any request should be relevant and as unintrusive as reasonably possible.

The Commission’s medical-documentation policy explains the distinction. If a request seems too broad, ask what information is needed and why. Ask whether a narrower request could address the workplace need.

Undue hardship has a particular legal meaning

The Human Rights Code identifies three considerations for undue hardship:

  • Cost.
  • Outside sources of funding.
  • Health and safety requirements.

A preference for existing arrangements does not establish undue hardship.

The assessment depends on the organization and circumstances. Any claimed costs or risks must be supported by evidence and assessed in context. Possible funding and ways to address risks also matter. Accommodation has legal limits. Neither “we cannot do that” nor “you must provide exactly this” is a complete analysis.

Keep the request and the response clear

Put your request in writing where possible. Describe the affected duty or working condition. Explain the relevant restriction and the adjustment you want to discuss. Supporting medical information can address the work-related need. A short follow-up can record any earlier conversation.

Keep dated records of the options, questions and responses. Update the employer if your needs change or an arrangement is not working. Accommodation is an ongoing process. An initial adjustment may need review.

Look carefully at any change that follows

A performance plan, role change or dismissal after an accommodation request may be relevant. The sequence does not prove discrimination or reprisal on its own. It should still form part of an assessment. Keep accommodation records alongside any performance or termination documents.

Seek advice before resigning, accepting a separation package or concluding that no options remain. Start with a clear record of your needs, proposed adjustments and the employer’s response. A diagnosis or job title alone cannot settle the legal questions.
