Not every termination comes with a formal letter and a walk to the parking lot. Sometimes employers force the issue another way: cutting your pay, stripping your responsibilities, moving you to a different city, or making the workplace so unbearable that staying isn't a real option. When that happens, Ontario law recognizes it for what it often is — a termination. It just goes by a different name: constructive dismissal.
If you're reading this in the middle of a sudden change at work, take a breath. The decisions you make over the next few days matter, and the wrong move can cost you tens of thousands of dollars in severance. Here's what constructive dismissal actually means, the five signs to watch for, and the steps you should take before you do anything else.
What Is Constructive Dismissal?
Constructive dismissal happens when an employer makes a unilateral, fundamental change to the terms of your employment — or creates an environment so toxic that you can't reasonably continue working there. You haven't been officially fired, but the law lets you treat the change as a termination and pursue the same wrongful-dismissal damages a fired employee could.
The catch: you have to actually take that step. Constructive dismissal isn't something the employer admits to. You have to recognize it, refuse the change, and (in most cases) leave — while preserving your right to sue. That's why getting the sequence right is so important.
The Legal Test: Potter v. New Brunswick Legal Aid, 2015 SCC 10
The Supreme Court of Canada laid out a two-branch framework in Potter v. New Brunswick Legal Aid Services Commission. A constructive dismissal exists where either:
- Branch 1 — Single fundamental breach: the employer commits a single act that substantially breaches an essential term of the employment contract (for example, a large unilateral pay cut or demotion); OR
- Branch 2 — Pattern of conduct: the employer's course of conduct, taken as a whole, demonstrates that it no longer intends to be bound by the contract (for example, ongoing harassment, hostility, or cumulative changes that make the role unrecognizable).
Courts apply Potter as a two-step analysis: first, identify the breach or course of conduct; second, ask whether a reasonable person in the employee's position would have felt the essential terms were being substantially changed.
Five Signs You May Have Been Constructively Dismissed
Not every workplace change qualifies. Minor adjustments and normal management decisions don't cross the line. But the following five patterns regularly do, and each one has been tested in Ontario courts.
Sign 1: A Significant Pay or Commission Cut
Your compensation is one of the most fundamental terms of your employment contract. Courts have consistently treated a unilateral cut of roughly 10% or more to base pay as a fundamental breach — and even smaller cuts can qualify if the total package is materially reduced.
The same logic applies to commission and bonus structures. If your employer rewrites the commission plan in a way that meaningfully reduces your earning potential, changes your territory so your pipeline disappears, or moves you off a bonus you've historically received, that can be a fundamental change — even if your base salary stays the same.
Sign 2: A Demotion or Major Reduction in Responsibilities
A demotion doesn't have to come with a pay cut to count. Losing your title, losing your direct reports, being stripped of decision-making authority, or being moved to a role that is materially different in nature can all amount to constructive dismissal.
Courts look at the substance of the change, not the label. "Senior Director, Strategy" reassigned to a vague advisory role with no team and no budget is a demotion, even if the business card still looks impressive. The question is whether the new role is fundamentally the job you were hired to do.
Sign 3: A Forced Relocation
Unless your employment contract clearly contemplates relocation, an employer cannot unilaterally require you to move — particularly to a different city or province. A mandatory relocation that wasn't part of your original bargain is one of the more clear-cut examples of a fundamental change.
Watch for soft framing: "the role is being relocated to our Calgary office" or "we're consolidating in Mississauga." If you live in Ottawa and the new location requires you to uproot your life, that's a fundamental change — not a routine business decision you have to absorb.
Sign 4: A Toxic Work Environment the Employer Won't Fix
This is the second branch of the Potter test in action. Sustained harassment, bullying, or hostile conduct — by a manager, a colleague, or the organization itself — can amount to constructive dismissal when the employer knows about it and fails to investigate or remedy it.
The bar isn't a single bad day. Courts look for a pattern: complaints that go ignored, retaliation after you raise concerns, or a workplace where the employer has effectively signaled it no longer intends to honour basic obligations like a safe and respectful environment. Document incidents, dates, witnesses, and every complaint you make.
Sign 5: A Drastic Change in Hours or Schedule
Being moved from a day shift to permanent nights, having your hours cut substantially, or being placed on indefinite unpaid leave can all rise to a fundamental change. Schedule is part of your contract whether or not it's written down — if it has been the consistent pattern of your employment, an employer can't unilaterally rewrite it.
"Temporary" layoffs are a particularly common trigger in Ontario. Outside the limited situations where layoffs are expressly permitted by your contract, an employer's decision to send you home without pay can itself be a constructive dismissal — regardless of what they call it.
Wondering What Severance You'd Be Entitled To?
Constructive dismissal claimants are entitled to the same reasonable notice as someone who was fired outright — often months of pay. Estimate your common-law range in 60 seconds.
Timing Matters: The Risk of Condonation
Constructive dismissal claims have a built-in trap. If you continue working under the new terms without protest for too long, a court can find that you accepted (or "condoned") the change — which means you lose your right to treat it as a termination.
There's no fixed deadline. The analysis is contextual, and courts will weigh how long you took, what you said, and whether you needed time to figure out your options. As a practical matter, the safer course is to act within weeks, not months, and to put your objection in writing the moment a change is announced.
Document everything. Save the email or memo announcing the change, write down what was said in any meeting, and send your own written objection so there is a clear paper trail.
What to Do If You Think You've Been Constructively Dismissed
The most expensive mistake people make is quitting on the spot. A clean resignation can wipe out a constructive-dismissal claim entirely, because the employer can argue you chose to leave for your own reasons. Here's the sequence to follow instead:
- Document the change in writing. Confirm what's changing, when, and on whose instruction. Save emails, meeting notes, and any policy or memo handed to you.
- Put your objection in writing. A short, professional email stating that you do not consent to the change and reserve your rights goes a long way to defeating any later argument that you accepted it.
- Consult an employment lawyer before walking out. The cost of a consultation is small compared to the value of a properly handled claim. A lawyer can tell you whether your facts meet the Potter test and what your notice period is likely to be.
- Decide your path. With advice in hand, you can choose to treat the change as a termination and pursue a claim, continue working under formal protest while you assess options, or negotiate a clean exit. Each path has trade-offs; the right one depends on your facts.
Common Employer Pushback (and Why It Usually Fails)
When you raise the issue, expect to hear some version of these lines. None of them, on their own, defeat a fundamental-change argument:
- "It's a business decision." Business need doesn't entitle an employer to unilaterally rewrite a contract. The change still has to be one you agreed to or one the contract clearly permits.
- "We have the right to manage." Management rights cover ordinary day-to-day decisions, not fundamental terms like pay, role, or location.
- "The contract is flexible." Most contracts aren't as flexible as employers claim, and vague language is generally read against the party that drafted it. A lawyer can tell you quickly whether the wording actually authorizes the change.
None of these responses should pressure you into accepting a change that materially alters your job. If anything, hearing them is a sign you should get advice sooner rather than later.
