Constructive Dismissal in Canada: The Test, Examples and Deadlines

What the Law Says

The leading authority is Potter v. New Brunswick Legal Aid Services Commission, 2015 SCC 10. The Labour Program’s own interpretation policy, IPG-033, confirms that the unjust dismissal provisions in s.240 reach constructive dismissal and that whether one has occurred is judged on an objective view of the employer’s conduct, not on how the employee perceives the situation.

The Two-Branch Test from Potter

In Potter, the Supreme Court explained that because employment contracts are dynamic in comparison with commercial contracts, courts have taken a flexible approach to deciding whether the employer’s conduct showed an intention no longer to be bound. Two branches of the test have emerged (para. 32). Either one is enough.

1. 1

   Branch one — a specific term of the contract was breached

   • Step one, objectively: did the employer unilaterally change the contract? A change an express or implied term already authorised, or one the employee consented to or acquiesced in, is not unilateral and so is not a breach. To count as a breach the change also has to be detrimental to the employee (Potter, para. 37).
   • Step two: would a reasonable person in the same situation as the employee have felt, at the time the breach occurred, that the essential terms of the employment contract were being substantially changed? A breach too minor to be seen that way is not constructive dismissal (Potter, para. 39, quoting Farber at para. 26).

   In plain terms: something important about the job changed without agreement, it left the employee worse off, and it was big enough that a reasonable person in the same seat would say the deal had changed. The Court described the question as always one of degree.

2. 2

   Branch two — a course of conduct, with no single term identified

   • An employer's conduct also amounts to constructive dismissal where it more generally shows that the employer intended not to be bound by the contract. Courts applying Farber have found constructive dismissal without identifying any specific term that was breached, where the employer's treatment of the employee made continued employment intolerable (Potter, para. 33).
   • This branch is necessarily retrospective: it looks at the cumulative effect of the employer's past acts, viewed in the light of all the circumstances, and asks whether they would lead a reasonable person to conclude the employer no longer intended to be bound (Potter, paras. 33 and 42).

   In plain terms: a pattern rather than a single event. Nothing on its own looks like a firing, but taken together the treatment says the employer has walked away from the deal.

The burden of establishing constructive dismissal rests on the employee, and an employee who establishes it is entitled to damages in lieu of reasonable notice of termination (Potter, para. 31). There is one exception. Where an administrative suspension is at issue, the burden shifts to the employer, which then has to show the suspension was justified; if it cannot, the breach is established and the burden shifts back to the employee for the second step (para. 41).

What This Means for You

Your employer does not have to hand you a termination letter to effectively fire you. If they significantly reduce your responsibilities, change your role, cut your pay, move you to a different location without agreement, create intolerable working conditions through sustained harassment, or systematically strip away the core elements of your job, you may have been constructively dismissed. The key question is: would a reasonable person in your position conclude that the employer no longer intended to be bound by the terms of the employment agreement?

Two practical consequences follow from the way the test is framed. First, because step one asks whether the change was unilateral, a change that was consented to or acquiesced in is not a breach at all — which is why carrying on quietly in a changed role for a long period tends to weaken the argument. Second, because the second step is measured at the time the breach occurred, the analysis looks at what a reasonable person would have felt then, not at how things turned out afterwards.

Is This Constructive Dismissal?

The statements below track the two branches of the Potter test. They are a way of organising the facts, not a score: a situation can match most of them and still fail on degree, and a single serious change can be enough on its own.

• Yes/NoA term of the job changed — pay, hours, duties, title, reporting line or work location — and the change was not agreed to.
• Yes/NoNothing in the employment contract, or in an established practice the employee accepted, already gave the employer the right to make that change.
• Yes/NoThe change left the employee worse off, rather than being neutral or an improvement.
• Yes/NoA reasonable person doing the same job would say an essential term had been substantially changed, not merely a detail adjusted.
• Yes/NoThe change was announced as a decision already taken, rather than put to the employee for agreement.
• Yes/NoWhere no single change stands out, there is a run of smaller ones whose combined effect transforms the role.
• Yes/NoWhere nothing in the contract changed at all, the treatment itself has made continuing at work intolerable.
• Yes/NoThe employee has not carried on in the changed role so long, and so quietly, that agreement to it could be inferred.
• Yes/NoAny suspension involved was indefinite, unexplained or unpaid, rather than a short and justified administrative step.
• Yes/NoThe sequence is documented objectively: dates, the job description before and after, and whether anyone else was treated the same way.

Examples and the Usual Analysis

The Supreme Court declined to generalise about which changes qualify, describing it as a highly fact-driven exercise in which the court asks whether the changes are reasonable and whether they fall within the scope of the employee’s job description or employment contract (Potter, para. 40). What follows is where each recurring fact pattern usually turns, not a prediction of outcome.

Deadlines by Jurisdiction

Constructive dismissal usually has two possible routes: a statutory complaint with a short deadline, and a civil action with a longer one. They are not interchangeable, and in Ontario they cannot both run on the same issue.

Section numbers appear above only where the section was read on the statute itself. Ontario’s consolidated statutes are served by an application that will not render for an automated check, so the Ontario employment standards rules are stated from the Ministry’s own guide pages and carry the Act name without a section number. The statutory minimum notice figures for all 14 jurisdictions are on the provincial standards pages.

What Usually Happens After You Leave

The notice period

An employee who establishes constructive dismissal is entitled to damages in lieu of reasonable notice of termination (Potter, para. 31). Two separate figures are in play. The statutory minimum is set by legislation and is the same whether the dismissal was announced or constructive: federally, 2 to 8 weeks of notice or pay in lieu depending on length of service, plus severance pay; in Ontario, a scale of 1 to 8 weeks. Common law reasonable notice is decided case by case by a court, is not set by any statute, and is normally the larger of the two. The severance calculator works through how the two relate, and can my boss fire me without cause in Canada covers the without-cause rules the same notice figures come from.

The duty to mitigate

Damages in lieu of notice are subject to the employee making a reasonable effort to mitigate by seeking an alternate source of income (Evans v. Teamsters Local Union No. 31, 2008 SCC 20). Earnings from a new job during the notice period normally reduce what the former employer owes rather than ending the claim. Evanswent further: in some circumstances the reasonable step is returning to work for the same employer for the balance of the notice period, which is part of why resignations in this area are rarely as clean as they look. A record of the job search — applications, interviews, offers and their dates — is what the mitigation question turns on.

Resigning in response

Timing matters on both branches. Ontario’s guide states that a constructive dismissal is treated as a termination under the ESA where the employee resigns in response to the change within a reasonable period of time. That mirrors the first step of branch one in Potter: a change the employee consented to or acquiesced in is not a unilateral change and so is not a breach. Working on in the changed role without objecting is the fact that most often ends the argument. The severance negotiation walkthrough covers what a departure conversation usually involves.

Real Example

What You Can Do

1. 1Documenting every change to your job duties, reporting structure, schedule, access, compensation, or working conditions with specific dates creates an evidentiary record of the cumulative effect.
2. 2Comparing your current role to your employment contract or job description preserves evidence of material differences between what you agreed to and what is actually occurring.
3. 3Noting whether changes coincide with a protected activity (complaint, accommodation request) establishes potential temporal proximity to protected conduct.
4. 4Consulting a lawyer before resigning is advisable, as resigning without legal counsel may impact your ability to claim constructive dismissal retroactively.
5. 5Under CLC s.240, employees with 12+ months of continuous service may file an unjust dismissal complaint within 90 days of the alleged constructive dismissal. Alternatively, a common law wrongful dismissal claim may be pursued through courts.

Warning Signs

• Your core job responsibilities are removed or significantly reduced without explanation
• Your reporting structure changes suddenly (new manager, new team) without consultation
• Your compensation is reduced, benefits are altered, or bonus structure changes unilaterally
• You are relocated to a different office, floor, or city without agreement
• Your title changes or your role is "restructured" in ways that diminish it
• Sustained harassment or hostile conditions that make it impossible to perform your job
• A series of small, individually defensible changes that collectively transform your position

What to Document

• Your original employment contract, job description, and any amendments
• Each change with the date it was implemented and whether your agreement was sought
• The cumulative effect of all changes on your role, compensation, and working conditions
• Whether business justification was provided for each change
• Whether similar changes were applied to other employees
• The timeline relationship between your complaints or protected activities and the changes

Where to File

Constructive Dismissal: Frequently Asked Questions

What is constructive dismissal in Canada?

Constructive dismissal is a firing the employer never announced. Where an employer's conduct shows an intention no longer to be bound by the employment contract, the employee can either accept the change or treat it as a repudiation and sue for wrongful dismissal (Potter v. New Brunswick Legal Aid Services Commission, 2015 SCC 10, para. 30). The Supreme Court called the word 'constructive' a signal that the dismissal is a legal construct: the employer's act is treated as a dismissal because of how the law characterises it. On the federal side, the Labour Program's interpretation policy IPG-033 says the same thing in administrative terms — the employer has failed to comply with the contract of employment in a major respect, and it is that failure, judged objectively, that separates a constructive dismissal from an ordinary resignation.

What is the test for constructive dismissal?

Potter sets out two branches. Under the first, a court identifies an express or implied term that was breached and then decides whether the breach was serious enough: was the change unilateral and detrimental (para. 37), and would a reasonable person in the same situation as the employee have felt that the essential terms of the contract were being substantially changed (para. 39)? Under the second, no specific term needs to be identified — conduct that, viewed in the light of all the circumstances, would lead a reasonable person to conclude that the employer no longer intended to be bound by the contract is enough, including treatment that made continued employment intolerable (paras. 33 and 42). The burden rests on the employee (para. 31), with one exception: where an administrative suspension is at issue, the burden shifts to the employer to show the suspension was justified (para. 41).

Is a pay cut constructive dismissal?

Not automatically, and the question is one of degree. Compensation is an essential term, so a unilateral and detrimental cut clears the first step of branch one without much argument. What decides the case is the second step: whether a reasonable person in the same job would have felt that an essential term was being substantially changed at the time the cut was imposed. The Supreme Court declined to generalise about which changes qualify, calling it a highly fact-driven exercise in which the court asks whether the change is reasonable and whether it falls within the scope of the employee's job description or contract (Potter, para. 40). The Labour Program treats a major reduction in hours, pay or status as constructive dismissal for federally regulated employees.

How long do I have to bring a constructive dismissal claim in Canada?

It depends on the route and the jurisdiction, and the shortest clocks are short. A federally regulated employee has 90 days for an unjust dismissal complaint to the Labour Program, and needs 12 consecutive months of continuous employment and no collective agreement coverage. In Quebec the complaint under section 124 of the Act respecting labour standards is due within 45 days of the dismissal and requires two years of uninterrupted service. British Columbia allows 6 months from the last day of work and Alberta 6 months from the last day of employment. Ontario's employment standards claim is generally due within 2 years, as is a civil wrongful dismissal action there, measured from the day the claim was discovered. The deadline table above sets each of these out with its source.

What happens to a constructive dismissal claim if the employee finds another job?

New earnings normally reduce what is owed rather than ending the claim. Where an employer ends the contract without notice it owes damages in lieu of notice, but that is subject to the employee making a reasonable effort to mitigate by seeking an alternate source of income (Evans v. Teamsters Local Union No. 31, 2008 SCC 20). Evans went further and held that in some circumstances the reasonable step is returning to work for the same employer for the balance of the notice period, which is one reason resignations in this area are rarely straightforward. Records of the search — applications, interviews, offers and their dates — are what the mitigation question turns on.
