About Sexual Harassment
Sexual harassment is a pervasive and serious issue in Ontario workplaces, constituting a form of sex-based discrimination. It is explicitly prohibited by Ontario's Human Rights Code (OHRC) and is also addressed under the Occupational Health and Safety Act (OHSA). The OHRC defines sexual harassment as engaging in a course of vexatious comments or conduct because of sex, sexual orientation, gender identity, or gender expression, where the conduct is known or ought to be known to be unwelcome. This can include unwelcome sexual advances, requests for sexual favours, sexually charged jokes, displaying offensive images, or inappropriate physical contact. Importantly, a single, severe incident can also qualify as sexual harassment if it has a lasting and harmful impact on the work environment.
Employers in Ontario have a dual responsibility. Under the OHSA, they must establish and maintain a workplace harassment policy, including a process for reporting and investigating incidents. Failure to investigate a complaint properly can lead to significant liability. Under the OHRC, employers have a duty to maintain a workplace free from discrimination and harassment. If an employer is aware of sexual harassment and fails to take prompt and effective action, they can be held responsible for creating a 'poisoned work environment.' This is an environment that has become hostile or intimidating due to the harassment. For an employee who is a target of such behaviour, the consequences can range from emotional distress to feeling forced to resign, potentially leading to a constructive dismissal claim. Because the legal pathways and potential remedies depend heavily on the specific facts of a situation, understanding your rights often requires a careful analysis of the events and the employer's response.
Frequently Asked Questions
What legally counts as sexual harassment in an Ontario workplace?
Under Ontario's Human Rights Code, it includes any unwelcome comments or conduct related to sex or gender that are vexatious. This can range from inappropriate jokes and displaying offensive material to unwanted touching and sexual solicitations. A single serious act can be enough to qualify.
Do I have to report sexual harassment to my HR department?
While you are not legally obligated to report to HR, it is often a necessary first step. Your employer has a duty to investigate under the Occupational Health and Safety Act once they are aware of a complaint. Reporting creates a record and triggers this duty.
Can I be fired for reporting sexual harassment?
No. It is illegal for an employer to retaliate against you for raising a human rights complaint or enforcing your rights under the OHSA. This is called a reprisal, and it is a separate offence under both the Human Rights Code and the OHSA.
What is the time limit for filing a sexual harassment claim in Ontario?
You generally have one year from the date of the last incident of harassment to file an application with the Human Rights Tribunal of Ontario (HRTO). For civil court actions like constructive dismissal, you typically have two years.
Can a single joke or comment be considered sexual harassment?
While sexual harassment often involves a 'course of conduct,' a single, serious incident can absolutely be sufficient. If a comment or action is severe enough to create a hostile or poisoned work environment on its own, it can meet the legal definition.
Can I sue my company if my coworker sexually harassed me?
You can't sue your coworker directly for harassment in civil court, but you can hold your employer accountable. Your employer has a legal duty to provide a harassment-free workplace. If they failed to prevent the harassment or did not respond appropriately, you can file a human rights application against both the harasser and the company.
When should I contact a lawyer about workplace sexual harassment?
You should consider contacting an employment lawyer if the harassment is severe, your employer has ignored your complaints or investigated them improperly, or if you have faced any form of retaliation for reporting the issue. A lawyer can help you understand your options, including filing a human rights claim or pursuing a constructive dismissal case.
Common Scenarios
- A supervisor repeatedly asks a subordinate employee on dates and makes comments about their clothing, creating a power imbalance and an uncomfortable work environment.
- A group of employees circulates sexually explicit memes and jokes in a company-wide chat channel, causing a colleague to feel ostracized and creating a poisoned work environment.
- After an employee reports being sexually harassed by a major client, their manager tells them to 'develop a thicker skin' and takes no action.
- At a company holiday party, a senior executive becomes intoxicated and makes unwanted physical contact with a junior employee.
- An employee is denied a promotion shortly after rejecting their manager's sexual advances, suggesting a quid pro quo situation.
What You Should Know
- Document every single incident of harassment in a private log. Include the date, time, location, what happened, what was said, and any witnesses.
- Review your employer's workplace harassment policy. This document, required by the Occupational Health and Safety Act, outlines the formal steps for making a complaint.
- If you feel safe to do so, clearly inform the harasser that their conduct is unwelcome. An email or text message can create a clear, time-stamped record of your objection.
- Preserve all evidence, including offensive emails, text messages, screenshots of chats, and notes from witnesses.
- If your employer's response to your complaint is inadequate or you face punishment for reporting, you should speak with an employment lawyer to protect your rights and explore legal remedies.

While dismissing claims for sexual harassment and constructive dismissal, the court ruled that the employer improperly deducted vacation pay, ordering reimbursement of $3,763 plus interest.
