Is Your Termination Clause Enforceable? Waksdale, Dufault, and What They Mean for Your Severance

When an Ontario employee is terminated without cause, one contractual provision usually determines more of the outcome than any other: the termination clause. If the clause is enforceable, it may limit the employee to something close to the minimums under the Employment Standards Act, 2000 — often a matter of weeks. If the clause is unenforceable, the common law right to reasonable notice applies instead, and that entitlement is frequently measured in months. The gap between those two outcomes can be worth tens of thousands of dollars or more.

This article explains why so many termination clauses fail, the main lines of decisions Ontario courts apply when assessing them, and what happens when a clause does not hold. It also explains something equally important: why the analysis only ever runs in one direction. Courts and lawyers can identify reasons a clause fails; no plain reading can confirm that a clause is valid. Before assessing any clause, it helps to know the size of what is at stake, and you can estimate your common law severance range in a few minutes to see the difference between the statutory floor and the common law entitlement.

Why the Termination Clause Is the Pivot of Every Severance Case

Ontario employment law provides two very different measures of what a terminated employee is owed. The first is the statutory floor: the Employment Standards Act, 2000 requires termination pay of one week per completed year of service (after three months of employment, capped at eight weeks), plus statutory severance pay for qualifying employees — those with five or more years of service where the employer has an Ontario payroll of $2.5 million or more, at one week per year prorated, capped at 26 weeks. Benefits must also continue through the statutory notice period. These amounts are minimums that no contract can undercut.

The second measure is the common law. Absent an enforceable clause saying otherwise, every employee has an implied contractual right to reasonable notice of termination, assessed using the Bardal factors — age, length of service, character of employment, and availability of similar work. Common law notice has no statutory cap and routinely exceeds the ESA amounts by a wide margin. The difference between ESA minimums and the common law entitlement is the core of most severance negotiations.

The termination clause is the mechanism employers use to try to displace the common law and substitute something smaller — usually the ESA minimums or a modest formula. That substitution only works if the clause is enforceable. And Ontario courts, applying a protective and employee-favourable approach to interpreting termination provisions, have found defects in a remarkable share of the clauses that have come before them. This is why the enforceability question is the pivot: it decides which of the two measures governs.

The Waksdale Line: One Defect Sinks the Whole Provision

The most consequential development in this area is the Waksdale line of decisions. The principle is this: if any part of a termination provision violates the ESA — for example, the for-cause clause — courts have held that the entire termination provision is unenforceable.

The reasoning treats the termination provision as a single scheme rather than a set of severable parts. Many contracts contain a for-cause clause purporting to deny all entitlements on termination for "cause" as that term is understood at common law. But the ESA disentitles an employee from statutory payments only on the narrower standard of wilful misconduct that is not trivial and not condoned — a higher bar than common law cause. A for-cause clause drafted to the common law standard therefore purports, in some circumstances, to pay less than the ESA requires. Under the Waksdale line, that defect is not contained to the for-cause clause: it takes down the without-cause clause with it, even if the without-cause clause would have complied with the ESA on its own, and even if the employer never alleges cause.

The practical consequence is striking. An employee terminated without cause, with a without-cause clause that appears ESA-compliant on its face, may nonetheless be entitled to full common law reasonable notice because of defective for-cause language elsewhere in the provision — language the employer never invoked. This interaction between cause language and clause enforceability is one of several reasons the for-cause standard in Ontario matters even to employees who were dismissed without any allegation of misconduct.

The Dufault Line: "At Any Time" and "Sole Discretion" Language

A second, more recent line of decisions concerns a phrase that appears in a very large number of Ontario employment contracts. Under the Dufault line of decisions, clauses claiming a right to terminate "at any time" or in the employer's "sole discretion" have been found to violate the ESA.

The difficulty with this language is that the employer's right to terminate is not, in fact, unfettered. The ESA restricts termination in specific circumstances — for example, in reprisal for exercising statutory rights or at the conclusion of certain protected leaves. A clause asserting an unqualified right to terminate at any time, or however the employer sees fit, overstates the employer's rights relative to the statute. Courts applying this line of decisions have treated that overstatement as an ESA violation, with the same consequence as any other defect: combined with the Waksdale principle that one defect invalidates the whole provision, the entire termination clause can fall.

Because "at any time" and "sole discretion" are boilerplate phrases found in countless templates — including contracts drafted relatively recently — this line of decisions has put a large number of existing clauses in doubt. Whether any particular clause is affected depends on its exact wording, but the prevalence of the language means many employees who assume their contract limits them to the minimum may be mistaken.

Machtinger: Below-ESA Language Is Void, and the Common Law Fills the Gap

The oldest of the doctrines in this area answers a question that matters enormously to remedies. Under Machtinger, a clause providing less than the ESA minimums is void, and the common law applies in its place — not the ESA-only floor.

This point is worth pausing on, because employers sometimes suggest the opposite: that if a clause fails, the employee simply gets the statutory minimum the clause was trying to approximate. That is not the law. A void clause is treated as if it were never written. The employee's entitlement reverts to the implied term of reasonable notice at common law, assessed under the Bardal factors, with no cap. A clause that promised two weeks per year but failed on a technical defect does not leave the employee with two weeks per year, or with the ESA formula — it leaves them with the full common law range. This remedial rule is what gives clause defects their financial significance, and it is deliberate: it removes any incentive for employers to draft aggressive clauses and rely on the statute as a safety net.

Other Recurring Defect Patterns

Beyond the specific doctrines above, Ontario courts have found termination clauses unenforceable on a range of recurring grounds, all rooted in the same principle: a clause that provides, or could in some circumstance provide, less than the ESA requires is void.

One recurring pattern involves benefits. The ESA requires an employer to continue benefit plan contributions through the statutory notice period. A clause that provides pay in lieu of notice but is silent on benefits, or that expressly limits the employee to salary alone, may in some circumstances provide less than the statute requires. Courts have treated benefits gaps of this kind as defects.

Another involves statutory severance pay. Termination pay and severance pay are separate ESA entitlements, and a clause drafted only around notice or termination pay may fail to account for severance pay for qualifying employees. A clause that caps the employee's total entitlement at an amount that could fall below the combined statutory entitlement contains a defect, even if the employee in question would not currently qualify for severance pay — the question is what the clause purports to permit, not what happened.

These examples are illustrative rather than exhaustive, and that is the point. The grounds on which clauses have been invalidated are numerous, they interact, and new ones continue to emerge as courts examine new wording. Any list of defects is a snapshot, not a checklist.

What Happens When a Clause Fails

When a termination clause is unenforceable, the employee's entitlement is assessed as though the contract contained no termination clause at all. The implied term of reasonable notice governs. Reasonable notice is assessed using the Bardal factors — age, length of service, character of employment, and availability of similar work — and typical ranges run from a few months for junior, short-service employees to twelve to twenty-four months for long-service senior employees, with exceptional cases exceeding that.

The financial difference is usually substantial. Common law damages are not limited to base salary: they generally reflect the full compensation the employee would have earned during the notice period, which can include benefits, bonus, commissions, and pension contributions, subject to the terms of the relevant plans and the duty to mitigate. An employee whose clause limited them to eight weeks, and whose common law range is twelve months, has a claim measured by the difference. That gap is the substance of most wrongful dismissal claims: the dismissal itself may have been lawful, but the compensation offered fell short of the entitlement.

It follows that an employee reviewing a severance offer should never treat the offer as final merely because it matches what the contract says. The contract only controls if the clause holds, and whether it holds is precisely the question in dispute.

No Visible Defect Does Not Mean the Clause Is Valid

This is the most important — and most commonly misunderstood — point in this area of law. The analysis of a termination clause runs in one direction only. It is possible to identify reasons a clause fails. It is not possible to confirm, from reading a clause, that it is enforceable.

The reasons are structural. The grounds of invalidity are numerous and continue to develop; a clause drafted carefully against last year's decisions may be vulnerable to a ground recognised this year. The defects often turn on subtle wording — a phrase that reads innocuously to a non-lawyer may be precisely the language that has been found to violate the ESA. And under the Waksdale line, the defect need not be in the part of the clause the employer relies on: it can sit anywhere in the termination provision. A reader who scans the without-cause clause and finds it unobjectionable has not assessed the provision the way a court would.

For employees, the practical upshot is this: the absence of an obvious problem in a termination clause is not evidence that the clause is valid, and no article — including this one — can tell you that your clause is enforceable. What a general article can do is explain why so many clauses fail and why the common law range remains relevant in every case until the clause has been properly assessed. The assessment itself requires legal review of the exact wording of the specific contract, because wording is everything in this area.

Practical Next Steps

For an employee who has been terminated and offered a package based on a contractual clause, the sensible sequence is straightforward. The first step is to understand the size of the question: calculate the common law severance range for your age, tenure, role, and job market, and compare it to what the clause and the offer provide. If the two numbers are close, the enforceability question matters less; if they are far apart — as they often are — the clause is carrying a great deal of weight and deserves scrutiny.

The second step is to have the clause itself reviewed before accepting any offer or signing any release. Because enforceability turns on exact wording and current law, this is a task for legal review rather than self-assessment. Many employees then proceed by way of negotiation: a demand letter setting out the common law entitlement and the grounds for questioning the clause can prompt a materially improved offer, since employers and their counsel understand the litigation risk an uncertain clause creates. Employees who prefer professional representation from the outset, or whose negotiations do not resolve the matter, should consult a licensed Ontario employment lawyer to assess the clause and the claim as a whole.

Frequently Asked Questions

Q1: What makes a termination clause unenforceable in Ontario?

A termination clause is unenforceable if it violates, or could in some circumstance violate, the minimum standards of the Employment Standards Act, 2000. Recurring defects include for-cause language that denies statutory entitlements more broadly than the ESA permits, language claiming a right to terminate at any time or in the employer's sole discretion, clauses that provide less than the statutory minimums, clauses that fail to continue benefits through the statutory notice period, and clauses that omit statutory severance pay. Under the Waksdale line of decisions, a defect in any part of the termination provision has been held to render the entire provision unenforceable, even the parts that comply on their own. Whether a specific clause contains a defect depends entirely on its exact wording, which is why legal review of the actual contract language is essential.

Q2: If my contract says I only get ESA minimums, is that all I am owed?

Not necessarily. A contract can limit an employee to the statutory minimums only if the termination clause that does so is enforceable, and enforceability is a contested legal question. Ontario courts have found a large share of the termination clauses they have examined to be unenforceable for violating the Employment Standards Act, 2000 in some respect. If the clause fails, the common law right to reasonable notice applies, which is frequently measured in months rather than weeks and has no statutory cap. An employee with a contract limiting them to ESA minimums should never simply assume the minimum is their ceiling. The common law range remains relevant in every case until the clause's enforceability has been properly assessed, and only a legal review of the specific wording can make that assessment.

Q3: What is the Waksdale line of decisions?

The Waksdale line of decisions stands for the principle that a termination provision in an employment contract is read as a whole. If any part of the provision violates the Employment Standards Act, 2000 — for example, a for-cause clause that purports to deny statutory entitlements in circumstances where the ESA would still require payment — courts have held that the entire termination provision is unenforceable. This is true even if the employer never relies on the defective part, and even if the without-cause portion of the clause would have complied with the ESA on its own. The practical consequence is significant: a defect buried in one sentence of a termination provision can restore the employee's full common law entitlement to reasonable notice.

Q4: Can I tell on my own whether my termination clause is enforceable?

No, and it is important to understand why the question only runs in one direction. It is sometimes possible to spot a likely defect — below-ESA language, or a claimed right to terminate at any time — but it is never possible to confirm from a plain reading that a clause is enforceable. The grounds on which Ontario courts have invalidated termination clauses are numerous, evolving, and often turn on subtle wording. A clause with no visible problem may still contain a defect that a court would recognise. The absence of an obvious defect is therefore not evidence of validity. Only a legal review of the specific clause, in the context of the whole contract and the current state of the law, can assess how a court is likely to treat it.

Q5: What happens to my severance if the termination clause fails?

If a termination clause is unenforceable, it cannot limit the employee's entitlement, and the common law implied term of reasonable notice applies in its place. Under Machtinger, a clause providing less than the ESA minimums is void, and the employee's entitlement reverts to common law reasonable notice, not merely the statutory floor. Common law notice is assessed using the Bardal factors — age, length of service, character of employment, and availability of similar work — and is frequently measured in months. For many employees, the difference between the clause-limited amount and the common law amount is the largest single variable in their severance outcome, often amounting to months of additional pay, benefits continuation, and bonus entitlements over the notice period.
