A toxic work environment can amount to constructive dismissal in Canada if your employer’s conduct becomes so serious that it fundamentally damages the employment relationship. This can happen when an employer engages in severe bullying, harassment or intimidation, or allows serious workplace mistreatment to continue.
Can you quit a toxic workplace and get severance? Yes, if the circumstances legally qualify as constructive dismissal. You may be entitled to compensation even though your employer never formally fired you.
However, not every toxic or unpleasant workplace meets the legal test. The seriousness of the conduct, how your employer responded and the circumstances of your departure all matter.
The employment lawyers at Samfiru Tumarkin LLP help non-unionized employees in Ontario, Alberta and British Columbia determine whether serious workplace mistreatment has effectively ended their employment and what severance they may be owed.

Can a Toxic Work Environment Be Constructive Dismissal?
Yes. A toxic workplace can amount to constructive dismissal when the employer’s conduct is serious enough to fundamentally breach the employment relationship.
Constructive dismissal happens when an employer effectively ends an employee’s job without formally firing them.
It can occur when the employer makes a major unwanted change to an important term of employment, such as a significant pay cut or demotion. It can also happen through serious conduct that makes it unreasonable to expect the employee to continue working under the existing employment relationship.
For example, imagine that a manager repeatedly humiliates an employee in front of coworkers. The employee reports the conduct, but the employer fails to address it. The behaviour continues and becomes increasingly severe.
Depending on the circumstances, the employer’s conduct and response may support a constructive dismissal claim.
However, a demanding boss, occasional disagreement or stressful work environment doesn’t automatically amount to constructive dismissal.
For a broader explanation of toxic workplaces, see our Toxic Work Environment in Canada guide.
What’s the Difference Between Quitting and Constructive Dismissal?
When you quit voluntarily, you choose to end your employment. With constructive dismissal, the employer’s conduct is serious enough that the law may treat the employer as having ended the employment relationship.
This distinction is important because an ordinary resignation doesn’t automatically entitle an employee to severance.
If constructive dismissal is established, however, the employee may be able to pursue compensation as though they had been terminated without cause.
When Is a Toxic Workplace Serious Enough for Constructive Dismissal?
A toxic workplace may qualify when the employer’s actions, viewed as a whole, show that it no longer intends to honour the employment relationship.
Canadian courts consider the seriousness of the behaviour and the surrounding circumstances. They look at whether the employer’s conduct has fundamentally changed the relationship, not simply whether the employee is unhappy.
The Supreme Court of Canada has recognized that constructive dismissal can arise from a serious breach of employment terms or from a series of employer actions that, taken together, show the employer no longer intends to be bound by the employment contract.
Relevant factors in a toxic-workplace case can include:
- Seriousness: How abusive, threatening or harmful was the conduct?
- Frequency: Was it repeated, ongoing or a particularly serious incident?
- Duration: How long did the behaviour continue?
- Management Involvement: Was a supervisor or senior manager responsible?
- Employer Knowledge: Did the employer know about the problem?
- Employer Response: Was the conduct properly addressed?
- Escalation: Did the mistreatment continue or become worse?
- Overall Effect: Did the conduct fundamentally damage the employment relationship?
Does Constructive Dismissal Require Repeated Harassment?
No. A pattern of serious mistreatment can support constructive dismissal, but repeated incidents aren’t always required.
One particularly serious act by an employer may fundamentally breach the employment relationship.
In other cases, several incidents that might seem less serious individually can become significant when considered together.
The important issue is whether the employer’s conduct meets the legal test in the circumstances.
What Doesn’t Usually Qualify as Constructive Dismissal?
Not every unpleasant situation amounts to constructive dismissal. For example:
- A manager giving legitimate negative performance feedback
- A reasonable warning about missed deadlines
- A personality conflict with a coworker
- An occasional workplace disagreement
- Ordinary work pressure or demanding expectations
- A management decision the employee dislikes but the employer is entitled to make
These situations can be stressful, but stress or unfairness alone doesn’t establish constructive dismissal.
Examples of a Toxic Work Environment That May Be Constructive Dismissal
Some workplace situations are more likely than others to raise constructive dismissal concerns.
1. Ongoing Bullying and Public Humiliation
A manager regularly screams at an employee, insults them in meetings or deliberately embarrasses them in front of colleagues.
If the behaviour is serious, continues over time and fundamentally damages the employment relationship, it may support constructive dismissal.
2. Serious Harassment That the Employer Ignores
An employee repeatedly reports abusive behaviour from a supervisor or coworker, but the employer fails to take appropriate action.
The employer’s knowledge of the problem and its response may become important evidence.
Read our Workplace Harassment in Canada guide.
3. Discrimination or a Poisoned Work Environment
An employee faces severe discriminatory remarks, harassment or degrading treatment connected to a protected characteristic, such as disability, race, religion or sex.
Serious discrimination can create a poisoned work environment under human rights law and may also support constructive dismissal, depending on the circumstances.
A poisoned work environment and constructive dismissal aren’t automatically the same legal claim. Each has its own requirements.
4. Retaliation After Reporting Workplace Misconduct
An employee reports serious harassment or another protected concern and then experiences threats, humiliation, targeted discipline or pressure to resign.
A pattern of serious retaliation may support constructive dismissal. Depending on the complaint and the law involved, it may also create separate reprisal rights.
5. An Employer Trying to Force an Employee to Quit
An employer may attempt to push an employee out by removing meaningful responsibilities, undermining their position, repeatedly threatening them or creating intolerable working conditions.
Where the conduct fundamentally breaches the employment relationship, the employee may have a constructive dismissal claim.
Learn more about Forced Resignation in Canada.
6. Several Serious Problems Happening Together
Sometimes constructive dismissal isn’t caused by one incident.
For example, an employee may experience repeated humiliation, deliberate exclusion, unfair targeting and management refusing to address complaints.
The combined effect of the employer’s conduct may be more significant than any single event.
Examples: When a Claim May Be Stronger or Weaker
| Workplace Situation | Constructive Dismissal Considerations |
|---|---|
| A manager gives an employee a poor performance review. | A legitimate review alone is unlikely to establish constructive dismissal. |
| A manager repeatedly humiliates and threatens an employee. | Serious, ongoing abusive conduct may support a claim. |
| Two coworkers occasionally disagree. | An ordinary conflict is unlikely to meet the legal test. |
| An employer knows about serious harassment but fails to address it. | The employer’s knowledge, response and severity of the conduct may support a claim. |
| An employee is repeatedly targeted after making a protected complaint. | Serious retaliation may raise constructive dismissal and separate legal concerns. |
These are illustrations, not automatic legal outcomes. Two employees facing similar behaviour may have different rights because of their employment circumstances and the evidence available.
Can Your Employer Be Responsible for a Toxic Workplace?
Yes. An employer’s own conduct, or its failure to respond appropriately to serious workplace misconduct, can be central to a constructive dismissal claim.
The situation is especially important when management is responsible for the mistreatment or knows about serious problems and allows them to continue.
What if Your Boss Is Harassing You?
Serious abusive behaviour by a manager may directly affect the employment relationship.
Repeated threats, humiliation, intimidation or other misconduct can become legally significant when viewed in context.
An employer can’t automatically avoid responsibility because the conduct was carried out by a supervisor rather than the company’s owner.
What if a Coworker Is Responsible?
An employer isn’t automatically constructively dismissing an employee whenever coworkers behave badly.
However, if the employer knows about serious harassment and fails to respond appropriately, its own conduct may become part of the problem.
The employer’s obligations and the seriousness of its response depend on the circumstances.
Do You Have to Report the Harassment First?
Not in every case, but reporting serious concerns can be important.
A written complaint can help establish that the employer knew what was happening and had an opportunity to respond.
However, an employee may already face serious misconduct by senior management, threats or other circumstances where the appropriate response requires careful consideration.
There is no universal rule that every employee must complete a lengthy HR complaint process before constructive dismissal can arise.
Get advice about whether, when and how to raise the problem before taking steps that may affect your position.
How Do You Prove Constructive Dismissal in a Toxic Work Environment?
To prove constructive dismissal, you need evidence of serious employer conduct that meets the legal test and explains why the employment relationship ended.
Simply telling your employer that your workplace is toxic won’t establish a claim.
Useful evidence can include:
- Incident Records: Dates, details and descriptions of serious workplace incidents.
- Emails and Messages: Communications showing harassment, threats, complaints or management responses.
- Witnesses: Coworkers or others who observed relevant behaviour.
- HR Complaints: Written reports and any responses from the employer.
- Performance Records: Reviews, warnings or documents relevant to allegations of unfair targeting.
- Changes to Your Job: Evidence of demotions, reduced duties, pay cuts or other significant changes.
- Medical Evidence: Relevant documentation where the conduct has affected your health.
- Resignation Communications: What you said to your employer, why you left and when.
Should You Keep a Timeline?
Yes. A dated timeline can help show how the conduct developed and whether it became more serious over time.
Record what happened, who was involved, when you raised concerns and what the employer did afterward.
For example, instead of writing “My boss has been abusive for months,” record the actual incidents, comments, dates and witnesses.
Do You Need Witnesses to Prove a Toxic Workplace?
Not necessarily. Witnesses can help, but other reliable evidence may also support your position.
Emails, messages, written complaints, records of meetings and your own detailed account may all be relevant.
Keep only documents you’re legally entitled to access. Don’t improperly remove confidential company information.
What if the Toxic Workplace Is Affecting Your Mental Health?
If workplace conditions are affecting your mental or physical health, seek appropriate medical care.
A medical condition may create separate rights involving disability accommodation or protected leave.
Medical evidence can also help explain how the workplace affected you, but a constructive dismissal claim still depends on the employer’s conduct and the applicable legal test.
Should You Quit a Toxic Workplace and Claim Constructive Dismissal?
Don’t resign before getting legal advice about whether your circumstances qualify as constructive dismissal.
An employee may feel that leaving is the only way to escape serious mistreatment. But how and when you leave can affect whether you’re entitled to severance.
What Happens if You Quit Too Soon?
If you resign and the employer’s conduct doesn’t legally amount to constructive dismissal, your employer may argue that you left voluntarily.
That could prevent you from obtaining the severance you expected.
Even where a legal issue exists, the timing and wording of your departure can create unnecessary complications.
What Happens if You Stay Too Long?
Remaining in a changed employment situation for an extended period without objection can create an argument that you accepted the circumstances.
However, employees don’t always need to leave immediately to protect their rights.
In some situations, continuing to work while clearly objecting and seeking legal advice may be appropriate.
There is no single resignation deadline that applies to every toxic-workplace constructive dismissal claim.
Should You Tell HR That You’re Considering Constructive Dismissal?
That depends on your situation.
Raising concerns in writing can help establish what your employer knew and how it responded. But threatening resignation or making legal allegations without a clear strategy can create complications.
It may be more appropriate to report specific conduct and seek advice before announcing that you consider yourself constructively dismissed.
Should You Send a Constructive Dismissal Resignation Letter?
Not automatically.
A carefully prepared letter may help explain why you’re leaving, but using the words “constructive dismissal” doesn’t prove your case.
Your letter, if one is appropriate, should reflect your circumstances and the legal advice you’ve received.
Read our guide to Constructive Dismissal Resignation Letters in Canada before sending anything.
What if You’ve Already Quit Because of a Toxic Workplace?
You may still have legal options.
An employment lawyer can review the events leading to your resignation, what you told the employer, how quickly you left and whether the conduct may support constructive dismissal.
However, an ordinary resignation doesn’t automatically become constructive dismissal because the employee later describes the workplace as toxic.
Canadian Court Case: Constructive Dismissal After Workplace Bullying
A well-known Ontario case shows how serious workplace abuse and an employer’s response can lead to a constructive dismissal finding.
Boucher v. Wal-Mart Canada Corp. (2014)
In Boucher v. Wal-Mart Canada Corp., an assistant manager experienced repeated humiliation and abusive treatment by her supervisor.
She complained to senior management. The employer investigated but concluded that her complaints were unsubstantiated and told her that she could be held accountable for making them.
Following further humiliating treatment, the employee left her employment and brought legal action.
A jury found that she had been constructively dismissed. The Ontario Court of Appeal subsequently considered and upheld important aspects of the damages awarded for the employer’s and supervisor’s conduct, while reducing certain punitive damages.
The case illustrates how serious abuse by management, combined with the employer’s response to complaints, can have substantial legal consequences.
It does not mean that every employee facing a difficult manager has a constructive dismissal claim.

How Much Severance Can You Get for Constructive Dismissal?
If your toxic workplace amounts to constructive dismissal, you may be entitled to severance as though your employer had terminated you without cause.
For many non-unionized employees, that compensation can be substantially greater than the minimum amounts required under employment standards legislation.
Depending on your circumstances, common-law severance can reach up to 24 months’ pay.
Your entitlement can depend on:
- Age: Your age when your employment ends.
- Length of Service: How long you’ve worked for your employer.
- Position: Your duties, seniority and responsibilities.
- Compensation: Salary, commissions, bonuses and benefits.
- Comparable Employment: The availability of similar work.
- Employment Contract: Whether an enforceable agreement affects your entitlement.
Your entitlement can also be affected by other legal rules, including the duty to mitigate employment losses. Learn more about severance pay in Canada.
Does a More Toxic Workplace Mean More Severance?
Not automatically. Once constructive dismissal is established, the usual common-law notice calculation focuses largely on your employment circumstances.
For example, an employee who was seriously harassed isn’t automatically entitled to more months of severance than someone who was constructively dismissed through a major pay cut.
However, particularly serious employer misconduct may create separate legal claims or remedies that affect the overall compensation available.
Can You Also Receive Compensation for Harassment or Emotional Distress?
Potentially, depending on the facts and the legal claims involved.
For example, discrimination connected to a protected characteristic may lead to human rights remedies, while certain serious employer conduct may support other recognized damages claims.
However, constructive dismissal doesn’t automatically entitle every employee to additional compensation for emotional distress, punitive damages or human rights damages.
The legal basis for each claim must be established.

Toxic Work Environment and Constructive Dismissal: Frequently Asked Questions
Can a toxic work environment be constructive dismissal in Canada?
Yes. Serious harassment, abuse or other employer misconduct can amount to constructive dismissal if it fundamentally damages the employment relationship. Not every difficult or unpleasant workplace meets the legal test.
Can you quit because of workplace bullying and still get severance?
Potentially. If the bullying and your employer’s conduct legally amount to constructive dismissal, you may be entitled to severance. Get advice before resigning so you understand whether the circumstances support a claim.
What is a poisoned work environment?
A poisoned work environment is a concept used in human rights law when serious discriminatory conduct contaminates the workplace. A poisoned workplace may also support constructive dismissal, but the legal tests are different.
Can one serious incident lead to constructive dismissal?
Yes, depending on the seriousness of the conduct and the circumstances. Constructive dismissal doesn’t always require months of repeated mistreatment.
Does your employer have to know about the harassment?
Employer knowledge can be important, especially when the misconduct comes from a coworker. However, the appropriate legal analysis depends on who was responsible, what happened and how the employer responded.
Can you claim constructive dismissal if HR ignores your complaint?
Potentially. If HR or management fails to address serious misconduct, that response may become relevant to a constructive dismissal claim. An ignored complaint doesn’t automatically establish that constructive dismissal occurred.
Can you claim constructive dismissal if your boss is the bully?
Yes, if the supervisor’s conduct is serious enough to fundamentally breach the employment relationship. The severity, frequency and surrounding circumstances are important.
Can you remain employed while considering constructive dismissal?
Sometimes. An employee may be able to object to the employer’s conduct and continue working while obtaining legal advice. However, waiting too long without objecting may affect a claim. The appropriate response depends on the circumstances.
Do you need to send a resignation letter to claim constructive dismissal?
There is no universal requirement to send a document titled “constructive dismissal resignation letter.” Written communication may be important evidence, but the decision to resign and the wording should be reviewed before you act.
Can you claim constructive dismissal after you’ve already resigned?
Possibly. An employment lawyer can review why you resigned, what the employer did and whether the surrounding circumstances support constructive dismissal. A voluntary resignation doesn’t automatically become constructive dismissal because the workplace was unpleasant.
How much severance can you get for a toxic workplace?
If constructive dismissal is established, eligible non-unionized employees may be entitled to termination compensation based on their age, length of service, position, compensation, employment contract and other relevant factors. Common-law severance can reach up to 24 months’ pay in appropriate circumstances.
What if you’re unionized and dealing with a toxic workplace?
Contact your union representative. Your collective agreement and grievance process may govern workplace harassment, employment changes and termination disputes.
Toxic Workplace? Don’t Quit Before You Know What You’re Owed.
If your employer is allowing serious bullying, harassment, discrimination or abusive treatment to continue, you may feel that resigning is your only option.
But leaving without advice could put your severance rights at risk. If your employer’s conduct amounts to constructive dismissal, you may be entitled to substantial compensation even though you weren’t formally fired.
The employment lawyers at Samfiru Tumarkin LLP help non-unionized employees in Ontario, Alberta and British Columbia assess constructive dismissal, understand their options and pursue the compensation they’re legally owed.
