Work-related stress can gradually affect sleep, concentration, mood, energy, and your ability to perform everyday tasks. When stress reaches a point where continuing to work is affecting your health, speaking with a doctor is an important step. A doctor can assess your symptoms, discuss treatment options, and determine whether you need time away from work.
In Ontario, there is no separate legal leave called “stress leave.” Instead, time away from work for stress or a related mental health condition may fall under Ontario’s sick leave or long-term illness leave provisions, depending on the circumstances. Since June 19, 2025, eligible employees with a serious medical condition can take up to 27 weeks of unpaid, job-protected long-term illness leave in a 52-week period, provided the statutory requirements are met.
Start With an Honest Conversation With Your Doctor
You do not need to walk into the appointment knowing exactly what medical terminology to use. Your doctor’s role is to evaluate your health, so focus on describing what you are experiencing and how it affects your ability to function.
Instead of simply saying, “I need stress leave,” explain what has been happening. For example, you could tell your doctor: “I have been under significant stress, and it is starting to affect my ability to work. I am having trouble sleeping, concentrating, and managing my normal responsibilities. I would like to discuss whether I need time away from work.”
Be specific about when the symptoms started, how frequently they occur, and whether they are getting worse.
Explain How Stress Is Affecting Your Ability to Work
One of the most useful things you can provide during the appointment is a clear description of how your condition affects your job.
Consider discussing:
- Difficulty concentrating or remembering tasks
- Persistent anxiety, irritability, or emotional distress
- Sleep problems or severe fatigue
- Panic symptoms or difficulty remaining calm at work
- Physical symptoms associated with stress
- Difficulty making decisions or completing normal duties
- Increased absenteeism or inability to maintain your usual schedule
- Problems functioning outside the workplace as well
Your doctor needs enough information to make an independent medical assessment. For disability-related documentation, medical evidence can be particularly important when demonstrating how a condition affects functional capacity. Government disability guidance similarly emphasizes documenting the condition, functional limitations, prognosis, treatment, and impact on the person’s ability to work.
Ask Your Doctor What Options You Have
Rather than asking your doctor to automatically write you off work for a particular period, ask what they recommend based on your medical situation.
You might ask:
“Do you think I am currently medically able to work?”
You can also ask whether modified duties, reduced hours, treatment, or a period away from work would be appropriate.
This approach gives your doctor room to assess your circumstances rather than simply documenting a predetermined outcome.
If your symptoms are severe enough that you cannot perform your job, your doctor may determine that you need time away from work and provide appropriate medical documentation where required.
Understand Ontario’s Sick Leave Rules
For employees covered by Ontario’s Employment Standards Act, sick leave provides up to three unpaid, job-protected days per calendar year for personal illness, injury, or medical emergency, provided the employee meets the eligibility requirements.
Importantly, since October 28, 2024, an employer cannot require a medical certificate from a qualified health practitioner as evidence for ESA sick leave. However, an employer can request other evidence that is reasonable in the circumstances. The rules are different for other types of leave and workplace benefits.
What Is Long-Term Illness Leave in Ontario?
Ontario introduced long-term illness leave on June 19, 2025. Eligible employees who have worked for their employer for at least 13 consecutive weeks may qualify for up to 27 weeks of unpaid, job-protected leave within a 52-week period because of a serious medical condition. A qualified health practitioner must provide a certificate stating that the employee has a serious medical condition and specifying the period during which the employee cannot perform their job duties because of that condition.
The certificate does not have to identify the specific medical condition. However, it must state that the condition is serious and specify the relevant period away from work. If stress has developed into a medically recognized condition that prevents you from working, these provisions may apply.
What If You Need Long-Term Disability Benefits?
An employment leave and disability insurance benefit are two different matters.
If your employer provides a long-term disability plan, you may have to submit a separate claim to the insurer. The insurer may request medical forms, clinical information, treatment records, or other evidence demonstrating why you cannot perform your job.
This is where the distinction between taking leave and pursuing a long term disability injury claim becomes important. The existence of a medical leave does not automatically mean an insurer will approve disability benefits. The insurance policy determines eligibility, and the insurer may assess your medical condition and functional restrictions against the policy’s definition of disability.
Your doctor may need to provide detailed information about your diagnosis, symptoms, limitations, treatment, and prognosis.
How to Make Your Doctor’s Appointment More Productive
Before your appointment, consider writing down:
- When your symptoms began
- Major changes in your sleep or appetite
- How your symptoms affect concentration and memory
- Physical symptoms you experience
- How often symptoms occur
- How your condition affects your work duties
- Treatments or medications you have already tried
- Any previous medical or mental health treatment
- Specific tasks at work that you can no longer perform reliably
Keeping a symptom record can help you explain your situation accurately rather than trying to remember everything during a short appointment. If your employer or insurer provides a specific medical form, bring it with you. Ask the doctor to review exactly what information is being requested.
What If Your Doctor Does Not Recommend Leave?
A doctor may conclude that you can continue working, perhaps with treatment or workplace modifications. That does not necessarily mean your concerns are insignificant. Medical assessments are based on the information available to the practitioner and their professional judgment.
You can ask what treatment or workplace adjustments may help and when you should return for reassessment.
If your condition changes, seek medical attention again and explain what has changed.
If you eventually need to pursue a long term disability injury claim involving a psychological or stress-related condition, maintaining consistent medical care and documentation may become particularly important. Disability insurers generally assess medical evidence alongside the actual requirements of the person’s occupation.
Protect Your Rights and Keep Your Records
If you are taking an extended absence, keep copies of communications with your employer, medical documentation, insurance forms, benefit statements, and correspondence from your insurer.
Do not assume that an approved workplace leave automatically establishes entitlement to long-term disability payments. Those are separate issues governed by different rules.
If an insurer denies or terminates your benefits, review the policy and the insurer’s reasons carefully. Deadlines can also apply to disability-related legal claims, so obtaining advice promptly can be important.
In short, asking a doctor for stress leave does not require a special script. The best approach is to describe your symptoms honestly, explain how they affect your ability to work, and ask your doctor to assess your options.
Ontario’s current rules distinguish between short-term sick leave and the newer long-term illness leave. If your condition prevents you from working for an extended period, review your employer’s leave policy and any applicable disability insurance plan separately.
For anyone dealing with a long term disability injury claim or a prolonged absence caused by a serious health condition, understanding the difference between employment leave, medical documentation, and disability benefits can help you take the appropriate next steps.
