Constructive Dismissal Explained
Constructive dismissal, sometimes called constructive termination, happens when an employer does not formally fire an employee but makes changes so significant that the employee is effectively pushed out.
In Ontario, constructive dismissal claims are complex. If proven, the law treats the employee as though they were wrongfully dismissed, often entitling them to months of severance compensation.

What Is Constructive Dismissal in Ontario?
Under Ontario law, constructive dismissal happens when:
A Fundamental Change Is Imposed Without Consent
Examples of fundamental terms include:
- pay
- hours
- job duties
- location
- reporting structure
- seniority or status
OR
The Workplace Becomes Toxic or Unbearable
Harassment, bullying, discrimination, or a poisoned work environment can also amount to constructive dismissal.
If constructive dismissal is proven, the resignation is treated as a termination without cause, triggering termination pay, severance pay, and potentially substantial common law damages.
⭐ Constructive Dismissal Meaning
Constructive dismissal in Ontario occurs when an employer makes a substantial, unilateral change to a fundamental term of employment or creates a toxic, intolerable work environment, leaving the employee no reasonable choice but to resign.
What Constitutes Constructive Dismissal in Ontario? (Legal Test)
Ontario courts use a two-step test (from Potter v. New Brunswick Legal Aid Services Commission):
Step 1:
- Did the employer make a unilateral change to a fundamental term of employment?
Step 2:
- Would a reasonable person feel the employer no longer intended to be bound by the contract?
If the answer is yes, constructive dismissal may be found.
Common Examples of Constructive Dismissal
Employees frequently search for “examples of constructive dismissal.”
Below are the most common triggers.
1. Pay Cuts
- A significant pay reduction (often 10–20% or more) can amount to constructive dismissal.
2. Major Demotion or Loss of Responsibilities
- Removing supervisory duties or reducing seniority.
3. Toxic Work Environment / Harassment
- Bullying, discrimination, or failing to investigate complaints.
4. Drastic Schedule or Shift Changes
- Moving an employee from day shifts to overnights without consent.
5. Forced Relocation
- Unreasonable travel distance or moving an employee to a different city.
6. Unpaid Suspension Without Justification
- Unless the employer can justify the suspension, courts may treat it as constructive dismissal.
Signs of Constructive Dismissal in Ontario
- Your employer reduces your pay or benefits
- Your job duties change dramatically
- You are demoted without cause
- Hours or location change significantly
- You’re excluded, bullied, or harassed
- You feel pressured to resign
- Management ignores or retaliates against complaints
If multiple signs appear together, the risk of constructive dismissal increases.
Do You Have to Resign to Claim Constructive Dismissal?
- No, not immediately.
- You must not quit without legal advice, because timing is critical.
- Quitting too early can weaken or even eliminate your claim.
- Waiting too long may be seen as accepting the changes.
How to Prove Constructive Dismissal (Step-by-Step)
To build a strong case:
✔ Step 1 — Document All Changes
- Emails, texts, memos, performance reviews, schedules, pay records.
✔ Step 2 — Communicate Your Objection (Politely, in Writing)
- Courts prefer evidence showing you did not accept the change.
✔ Step 3 — Track the Timeline
- Was the change sudden? Drastic? Coercive?
✔ Step 4 — Assess Whether the Change Is “Fundamental”
- A lawyer can help compare your old vs. new role.
✔ Step 5 — Obtain Legal Advice Before Resigning
- A misstep can reduce your entitlement.
How to File a Constructive Dismissal Claim in Ontario
Most employees resolve cases through:
- Lawyer negotiations
- Demand letters
- Mediation or settlement discussions
- Civil litigation (if necessary)
The Ministry of Labour does not handle constructive dismissal monetary claims; they belong in court, where damages are significantly higher.
⭐How Long Does a Constructive Dismissal Case Take?
- Simple negotiated cases: 2–8 weeks
- Mediated cases: 3–6 months
- Litigation: 1–2 years
Most settle early, without trial.
Constructive Dismissal Settlements in Ontario
Settlements are usually based on common law notice, not ESA minimums.
Ontario courts award compensation based on:
- age
- length of service
- position and seniority
- availability of similar jobs
- circumstances of the dismissal
- employer bad-faith conduct
⭐Typical Constructive Dismissal Settlement in Ontario
- 3–24 months of pay, including salary, benefits, bonus, commissions, RRSP/pension contributions, and more.
This is why constructive dismissal claims often result in significant payouts.
Constructive Dismissal and Toxic Work Environments
Ontario courts recognize harassment-based constructive dismissal where:
- complaints are ignored
- management contributes to the toxicity
- workplace becomes objectively intolerable
Human rights damages may also apply if discrimination is involved.
Employer Risks and Responsibilities in Ontario
Employers face major risks if changes are mishandled:
- common law damages
- aggravated + punitive damages
- human rights penalties
- reputational damage
- legal costs
