Your employer can’t punish you for exercising protected workplace rights in Ontario. If you raise a legitimate employment standards, health and safety or human rights concern and your employer responds by firing, threatening, disciplining, demoting or otherwise penalizing you, that can be an illegal reprisal.
Workplace retaliation and reprisal mean essentially the same thing: negative treatment because an employee asserted a protected right, made a protected complaint or participated in a protected process.
The Quick Answer: Is workplace retaliation illegal in Ontario? Yes, when your employer is punishing you for exercising a right protected by law. Ontario’s Employment Standards Act (ESA), Occupational Health and Safety Act (OHSA) and Human Rights Code all contain reprisal protections.
Serious retaliation can also fundamentally change your employment relationship and amount to constructive dismissal in Ontario, allowing you to leave and pursue severance rather than simply resigning.

What Is Workplace Retaliation in Ontario?
Workplace retaliation happens when an employer takes negative action against an employee because the employee exercised or tried to enforce a protected workplace right.
Ontario employment legislation commonly uses the word reprisal.
A reprisal can involve:
- Firing or threatening to fire you
- Disciplining or suspending you
- Demoting you
- Reducing your hours or pay
- Giving you undesirable shifts or duties
- Placing you on an unjustified performance improvement plan
- Taking away responsibilities or opportunities
- Threatening or intimidating you
- Pressuring you to resign
The negative treatment alone is not enough. There needs to be a connection between what the employer did and a workplace right you exercised or tried to enforce.
What Workplace Complaints Are Protected in Ontario?
There is no single Ontario law covering every form of workplace retaliation. Your protection depends on the right you exercised.
Employment Standards Act reprisals
The Ontario Employment Standards Act prohibits employers from retaliating against employees for exercising rights under the ESA.
Examples include asking your employer to comply with minimum employment standards, asking questions about your ESA rights, filing an Employment Standards complaint, providing information during an investigation or taking a job-protected ESA leave.
Your employer can’t punish you because you insisted on receiving a legal minimum entitlement.
Health and safety reprisals
The Occupational Health and Safety Act protects workers who exercise rights under Ontario’s workplace health and safety laws.
That includes employees who:
- Raise a health or safety concern
- Ask the employer to follow health and safety law
- Participate in a health and safety process or investigation
- Give evidence about a workplace safety issue
- Exercise a legal right to refuse unsafe work
Workers are also protected when they properly raise concerns about workplace harassment in Ontario.
Human rights retaliation
Ontario’s Human Rights Code protects employees from reprisal for claiming or attempting to enforce their human rights.
This can include retaliation because you:
- Reported discrimination
- Raised concerns about harassment connected to a protected ground
- Requested disability or other human-rights accommodation
- Participated in someone else’s human rights complaint
- Refused to participate in discrimination against another person
See our guides to workplace discrimination in Ontario, the duty to accommodate and the Ontario Human Rights Code.
Do you have to file a formal complaint first?
No—not in every situation. Human rights protection against reprisal can apply when you simply try to assert your Code rights. You don’t have to wait until a formal Human Rights Tribunal application has been filed.
The same practical lesson applies broadly: put legitimate workplace concerns in writing so there is a clear record of what you raised and when.
Examples of Workplace Retaliation in Ontario
You complain about harassment and are suddenly disciplined
You have positive performance reviews for years. After making a harassment complaint, you suddenly receive written warnings for issues that were never raised before.
That timing does not automatically prove retaliation, but it is a serious warning sign that should be documented and reviewed.
You request accommodation and lose responsibilities
You tell your employer that a disability requires accommodation. Soon afterward, important responsibilities are removed and you are excluded from opportunities you previously received.
If those decisions are punishment for asserting your accommodation rights, they can violate the Human Rights Code.
You report unsafe work and your hours are cut
After raising a legitimate safety issue, your employer significantly reduces your shifts while comparable employees continue receiving their normal hours.
That can be an OHSA reprisal if the reduction happened because you exercised a protected safety right.
You take a protected leave and are penalized when you return
Employees exercising ESA leave rights can’t be punished for doing so. An employer can’t use a protected leave itself as a reason to discipline, demote or terminate an employee.
You make a complaint and are put on a PIP
A performance improvement plan is not automatically retaliation. Employers are allowed to address genuine performance concerns.
But a sudden or unsupported PIP imposed immediately after a protected complaint deserves scrutiny—particularly where the allegations contradict your established performance history. See our guide to performance improvement plans in Ontario.
How Do You Know if Your Employer Is Retaliating Against You?
Employers rarely put in writing, “We are disciplining you because you complained.” The connection often has to be determined from the surrounding facts.
Important warning signs include:
- Timing: Negative treatment begins shortly after you exercise a protected right
- A sudden change in treatment: Your performance was acceptable until the complaint
- Inconsistent explanations: The reason for the employer’s decision keeps changing
- Different treatment: Other employees are not punished for similar conduct
- Escalation: Minor issues suddenly result in severe discipline
- Pressure to resign: Management begins making it increasingly difficult for you to remain employed
None of these factors has to exist in every case. The complete timeline matters.
Can your employer still discipline you after you make a complaint?
Yes. Exercising a protected right does not give an employee immunity from legitimate discipline, performance management or termination for unrelated reasons.
The employer’s decision becomes a reprisal when the protected activity is the reason for the punishment.
If your employer starts building a disciplinary record after your complaint, review your rights around progressive discipline in Ontario and respond to significant inaccuracies in writing.
What if your complaint isn’t legally protected?
Not every disagreement with management triggers statutory reprisal protection.
For example, complaining that your boss is unpleasant or that you disagree with a business decision does not automatically engage the ESA, OHSA or Human Rights Code.
However, severe punishment or major changes to your employment can still raise other legal issues, including constructive dismissal. What matters is identifying the actual right involved rather than relying only on the word “retaliation.”
What if You’re Fired or Forced Out After Making a Complaint?
Fired after exercising a protected right
Your employer can’t legally fire you because you exercised a protected ESA, health and safety or human rights right.
If retaliation caused the termination, you can have rights beyond an ordinary severance claim. The available remedy depends on which law was violated and can include compensation or, in some statutory proceedings, reinstatement.
The termination also needs to be reviewed for wrongful dismissal and severance pay.
Your employer tries to make you quit instead
Retaliation does not always end with an obvious firing.
An employer might instead:
- Demote you
- Cut your pay
- Reduce your hours
- Suspend you
- Remove significant duties
- Create increasingly hostile working conditions
If those changes fundamentally damage the employment relationship, they can amount to constructive dismissal.
That can allow you to leave the job and pursue full severance rather than resigning with nothing. Depending on factors such as age, position, length of service and the availability of similar work, severance can reach 24 months’ pay.
What Should You Do if Your Employer Retaliates Against You?
- Create a timeline. Record when you exercised the protected right and what happened afterward.
- Keep relevant records. Preserve emails, messages, warnings, schedules, performance reviews and other documents you are legally entitled to retain.
- Put important concerns in writing. Make the employer aware that you believe the treatment is connected to the right you exercised.
- Respond to false discipline. Don’t allow a seriously inaccurate warning or performance allegation to become the only written version of events.
- Continue doing your job. Don’t give the employer an unrelated disciplinary issue while challenging retaliation.
- Don’t resign. A resignation can affect severance and constructive dismissal rights.
- Get advice promptly. Different retaliation claims have different processes and deadlines.
Where do you make a retaliation complaint?
The correct process depends on the right involved:
- ESA retaliation: Employment Standards complaints are handled through Ontario’s Ministry of Labour process.
- OHSA retaliation: Reprisal complaints can be brought to the Ontario Labour Relations Board.
- Human rights retaliation: Applications can be brought to the Human Rights Tribunal of Ontario.
Those processes have different remedies and deadlines. If retaliation also resulted in termination or constructive dismissal, there can be additional employment-law claims to consider.
Workplace Retaliation Ontario: Frequently Asked Questions
Can my employer fire me for making a complaint?
Not because you exercised a protected workplace right. Your employer can still terminate you for legitimate reasons unrelated to the complaint, but it can’t use termination as punishment for asserting ESA, health and safety or human rights protections.
Is retaliation the same as reprisal?
Yes, in practical terms. “Retaliation” is the common expression. Ontario workplace legislation typically uses “reprisal” to describe punishment for exercising protected rights.
Can I be punished for making a harassment complaint?
No, not for properly exercising rights protected under Ontario workplace safety or human rights law. Your employer can still address unrelated misconduct or legitimate performance issues.
Can retaliation happen without being fired?
Yes. Discipline, suspension, demotion, reduced pay or hours, intimidation and other penalties can all amount to retaliation when imposed because you exercised a protected right.
Can I claim retaliation if my original complaint was unsuccessful?
Yes in a human rights context. You do not have to prove that the original Human Rights Code violation actually occurred in order to establish reprisal. The issue is whether you were retaliated against because you tried to claim or enforce a Code right.
Can retaliation amount to constructive dismissal?
Yes. A serious demotion, pay cut, loss of hours, suspension or pattern of hostile treatment can amount to constructive dismissal when it fundamentally changes the employment relationship.
Should I quit if my employer is retaliating against me?
Not before getting legal advice. If the conduct amounts to constructive dismissal, how you respond and how you leave the job can affect your ability to claim severance.
