Stress Leave (Ontario) Explained
Ian2025-11-13T16:22:31-04:00In Ontario, stress leave has become an increasingly important issue for both employees and employers. Rising awareness of mental health and workplace stress means that more employees are seeking time off to recover, while employers are grappling with how to meet their legal obligations.
Whether you’re an employee struggling with stress at work or an employer managing a stress leave request, understanding your rights, responsibilities, and options is essential. This article explains what stress leave in Ontario involves, the legal protections available, and how seeking legal advice can help you move forward with clarity.
What Is Stress Leave in Ontario?
“Stress leave” refers to time away from work taken due to stress, burnout, anxiety, depression, or other mental health challenges. While stress leave isn’t specifically named in Ontario legislation, employees may be entitled to leave under existing legal protections, including:
- The Employment Standards Act, 2000 (ESA)
- The Ontario Human Rights Code
- Employment insurance sickness benefits
- Short-term and long-term disability benefits (if applicable)
What Are Your Rights to Stress Leave in Ontario?
Under the Employment Standards Act (ESA), employees in Ontario who have worked for at least two consecutive weeks are entitled to:
- Three unpaid sick days per calendar year, which may be used for stress leave.
However, this is only the minimum standard. Your employment contract, company policy, or a collective agreement may provide additional leave or paid sick days.
More importantly, under Ontario’s Human Rights Code, if your mental health condition rises to the level of a disability, your employer has a legal duty to accommodate you to the point of undue hardship. This can include granting extended unpaid time off or modifying your job duties to reduce stress.
As Christopher Achkar, employment lawyer and founder of Achkar Law, explains:
“If you’re facing stress at work or dealing with an employee’s stress leave request, you don’t have to figure it out alone. Speaking to a lawyer before making any decisions can help you understand your rights, avoid legal risks, and move forward with confidence.”
Mental Health Leave Ontario: The Role of Medical Documentation
When you request stress leave from work, your employer may require basic medical documentation from a doctor or qualified health practitioner. The employer is entitled to know:
- That you are unable to work due to a medical condition
- The expected duration of your leave
Employers do not have the right to demand a diagnosis or personal medical details.
What Happens If Your Employer Denies Stress Leave?
If your employer refuses your request for stress leave, retaliates against you, or terminates your employment, you may have grounds for:
- Constructive dismissal
- Human rights complaints
- Wrongful dismissal claims
- Employment Standards Act complaints
Such actions could entitle you to severance pay, damages for discrimination, or bad faith damages.
“Workplace stress can be overwhelming, both emotionally and financially. Employees often don’t realize they have legal rights to request stress leave or accommodation, while employers sometimes mishandle these requests without meaning to. The key is early action, legal clarity, and an approach grounded in respect and fairness for all parties.”
