What Is It?
Constructive dismissal occurs when an employer makes a fundamental unilateral change to an employee’s working conditions — without the employee’s consent — that effectively amounts to firing them. The employee hasn’t been formally terminated, but the change is so significant that they are entitled to treat the employment relationship as having been terminated by the employer and claim wrongful dismissal damages.
This doctrine comes from the common law principle that both parties must agree to significant modifications to an employment contract. A unilateral breach of the core terms of employment entitles the employee to treat the contract as repudiated.
What Changes Qualify as Constructive Dismissal
Courts look for changes that are fundamental to the employment contract:
Strong grounds (usually qualify):
- Significant salary reduction (generally 10%+ is a strong indicator; courts have found 5% sufficient in some cases)
- Significant demotion — reduction in title, authority, or responsibility
- Forced relocation to a different city without reasonable justification or notice
- Removal of core job duties and replacement with substantially lesser duties
- Creating a poisoned work environment through harassment or discriminatory treatment
Weaker grounds (may or may not qualify):
- Changes to minor workplace perks
- Changes to work schedule within the same role
- Temporary salary reductions during documented business hardship
- Changes to benefits (may qualify if substantial)
The Critical Timing Requirement
You must resign promptly after the change occurs. If you continue working under the new terms for an extended period (months), courts may find that you’ve accepted the change — eliminating your constructive dismissal claim.
- File EI immediately using code “constructive dismissal” or contact a lawyer before resigning
- Do not sign any documents or accept any offers under the new terms
- Keep the change documented: email from your employer announcing the change is ideal evidence
Damages — What You’re Entitled To
If constructive dismissal is established, you are entitled to the same damages as if you had been wrongfully dismissed:
Common law reasonable notice based on:
- Length of service (often 1 month per year of service as a starting point)
- Age (older employees in specialized roles get more)
- Nature of the position (senior/specialized positions get more)
- Availability of comparable employment
For a 45-year-old manager with 10 years of service, reasonable notice commonly ranges from 12–20 months of salary.
Statutory minimums under the applicable Employment Standards Act (federal Canada Labour Code or provincial) provide a floor — but common law damages are typically much higher.
What Most People Don’t Know
- You can pursue constructive dismissal while employed. You don’t have to resign immediately — but you must protest the change promptly in writing and not accept the new terms.
- A verbal protest is not enough. Write to HR and your manager in writing (email is sufficient) stating that you do not accept the change and consider it a fundamental breach of your employment contract.
- Courts assess mitigation. After leaving, you have an obligation to look for new work. Your damages are reduced by earnings from new employment during the notice period.
- Severance pay may exceed notice. For federally regulated employees with more than 12 years of service, “severance pay” under the Canada Labour Code (separate from and in addition to termination pay/notice) is owed.
Frequently Asked Questions
My employer reduced my salary by 15% citing COVID-like “business challenges.” Does that qualify?
Courts have found temporary salary reductions imposed unilaterally during documented business hardship to sometimes not constitute constructive dismissal, particularly if other employees were similarly affected. However, a permanent or extended unilateral 15% reduction for a single employee is strong grounds. Consult an employment lawyer.
I’ve been working under the new conditions for 4 months. Have I lost my right to claim constructive dismissal?
Possibly. Courts often find that continuing to work under new conditions for several months constitutes acceptance of the change. However, if you’ve been protesting in writing throughout, courts may still find constructive dismissal. Get legal advice quickly.
Can I collect EI while pursuing a constructive dismissal claim?
Yes. When you resign due to constructive dismissal, you can apply for EI and indicate you were “constructively dismissed” — ESDC treats this as a dismissal for EI purposes, not a voluntary quit. If Service Canada denies your claim, you can appeal.
Do I need a lawyer to pursue a constructive dismissal claim?
Not necessarily — small claims court in many provinces handles employment claims up to $35,000. But for larger claims (long service, high salary), an employment lawyer working on a contingency basis is common. Consultations are often free.
