Can My Employer Ask for Medical Information in Ontario? Your Rights Explained
Ian2026-05-15T11:45:00-04:00Medical information requests from employers are one of the most frequently misunderstood areas of Ontario employment law. Employees often feel pressured to share more than they are legally required to. Employers sometimes request more than they are entitled to. Understanding exactly where the line sits protects both sides.
Has your employer demanded your diagnosis or medical records?
Over-disclosure of medical information can harm your rights. If your employer has requested more than they are legally entitled to, or has taken action against you over medical information, you may have legal protections under Ontario law.
Call: 1-800-771-7882 Speak With a Human Rights LawyerWhat medical information is an employer entitled to in Ontario?
Ontario law sets clear limits on what medical information an employer may request and use. The framework is governed by the Ontario Human Rights Code, the Employment Standards Act, 2000, and the Personal Health Information Protection Act (PHIPA). Medical requests must be reasonable, necessary, and compliant with these privacy protections.
Employers are generally entitled to
- Confirmation that you are unable to work
- The expected duration of your absence
- Functional limitations affecting your job duties
- Whether workplace accommodation is required
- Work restrictions relevant to your role
Employers are not entitled to
- Your specific diagnosis
- Detailed treatment information
- Your full medical history
- Medication lists (unless directly relevant to accommodation)
- Unrelated medical conditions
Can my employer ask why I am sick?
In most cases, no. Your employer may request confirmation that you are unable to work and how long you will be absent, but they are generally not entitled to know your specific diagnosis or the reason for your illness.
Can my employer ask for a doctor's note in Ontario?
Yes, but only in reasonable circumstances. Employers may request a doctor's note to confirm inability to work, verify functional limitations, or support an accommodation request. Blanket or excessive note requirements that apply to every absence, however short, may violate the Employment Standards Act, 2000 and privacy obligations.
Can my employer contact my doctor directly?
Generally, no. An employer cannot contact your doctor or access your medical records without your written consent. Any direct contact with your physician requires your express authorization.
Unsure what you are required to disclose?
Medical information requests can feel intrusive, and over-disclosure can harm your legal position. Our team can advise you on exactly what you are required to provide and what you can decline.

While you are not required to disclose your diagnosis, you do have responsibilities in the accommodation process. Employees are generally expected to provide enough information to allow the employer to assess and implement a reasonable accommodation.
You may need to disclose
- Functional limitations relevant to your role
- Work restrictions recommended by your physician
- Estimated return-to-work timeline
- Whether accommodation is required and what type
You do not need to disclose
- Your specific diagnosis
- Detailed medical history
- Unrelated medical conditions
- Medications (unless directly relevant)
What happens if you refuse to provide medical information?
If you refuse to provide reasonable confirmation of incapacity, your employer may deny sick pay or benefits, delay processing your accommodation request, or seek further clarification before taking action. However, they cannot demand invasive or excessive disclosure, contact your physician without consent, or discipline you for refusing to provide information beyond what the law requires.

Frequently asked questions about medical information and employers in Ontario
What medical information is my employer entitled to in Ontario?
Employers are entitled to confirmation of inability to work, the expected duration of absence, functional limitations affecting job duties, and whether accommodation is required. They are not entitled to your diagnosis, full medical history, or treatment details. Requests must be limited to what is reasonably necessary under the Ontario Human Rights Code and PHIPA.
Can my employer call my doctor to verify a note?
No, not without your written consent. Employers cannot contact your physician directly or access your medical records without your express authorization. Doing so without consent may violate PHIPA and other privacy protections.
Do I have to disclose my medical condition to my employer?
You do not have to disclose your specific diagnosis. You are generally required to provide enough information to confirm that you cannot work and to allow the employer to assess accommodation needs. The key distinction is between functional limitations, which must be disclosed, and diagnosis, which generally does not need to be.
Can an employer ask for my medical records?
No. Employers are not entitled to full medical records. They may only request information necessary to confirm work restrictions, assess accommodation needs, or administer benefits. Requests must be limited and proportionate to the legitimate workplace purpose.
When can an employer ask for a doctor's note in Ontario?
Employers may request a doctor's note in reasonable circumstances, such as confirming inability to work for an extended absence, verifying functional limitations, or supporting an accommodation request. Blanket policies requiring notes for every absence, including very short ones, may conflict with the Employment Standards Act, 2000.
Can my employer ask what medications I take?
Generally, no. Medication information is considered sensitive medical information. The exception is where knowledge of specific medications is directly and genuinely relevant to an accommodation need or a workplace safety concern. Even then, the request must be limited to what is necessary.
Can my employer share my medical information with others?
No. Medical information must be kept confidential and may only be shared with those who have a direct and legitimate need to know in the context of the accommodation process. Broader disclosure may violate PHIPA and the employee's privacy rights.
What happens if I refuse to provide medical documentation?
Refusing reasonable documentation may result in denial of sick pay or benefits, a delay in accommodation, or a request for further information. However, your employer cannot demand documentation that goes beyond what is legally required, and any adverse action taken in response to a reasonable refusal may be challenged.
Can an employer ask about my mental health history?
No. Mental health conditions are disabilities under the Ontario Human Rights Code and are subject to the same protections as physical health conditions. Employers are not entitled to your mental health history. They may only request information about current functional limitations and accommodation needs.
Can an employer require a medical assessment?
In some circumstances, an employer may request that an employee undergo an independent medical examination, particularly where the existing documentation is insufficient to assess accommodation needs. However, this must be reasonable, proportionate, and connected to a legitimate workplace purpose. Blanket requirements for independent assessments are not always permissible.
