Fixed-Term vs. Indefinite Employment Contracts in Ontario: A Guide for Employers

A fixed term contract in Ontario employs a person for a defined period or until a specific task is finished. When the term ends naturally, no notice is owed. But if the employer terminates early and the contract has no valid early-termination clause, the employer generally owes wages for the entire remaining term, with no duty to mitigate.

That last sentence is where many Ontario employers get blindsided. A fixed-term contract feels like the cleaner, lower-risk option. It has a built-in end date, so it seems easier to exit than an open-ended relationship. In practice, the opposite is often true. A poorly drafted fixed-term contract can expose an employer to far more liability than an indefinite contract ever would.

This post compares the two contract structures, walks through the case law that defines the risk, and explains why an indefinite-term contract with a carefully drafted termination clause is usually the safer default. It covers Ontario law only. It is also the hub of a broader series on employment contracts, with companion guides planned on probation periods, temporary layoffs, drafting enforceable termination clauses, and the duty to mitigate.

What Is a Fixed-Term Employment Contract in Ontario?

A fixed-term employment contract hires an employee for a set period, such as one year, or until a specific task or project is complete. The defining feature is a clear, predetermined end point. When that end point arrives, the employment relationship ends on its own.

At natural expiry, the employer generally does not owe statutory notice or termination pay. Under Ontario Regulation 288/01, made under the Employment Standards Act, 2000 (ESA), an employee hired for a defined term is exempt from termination entitlements when the term simply runs out. This is the feature that makes fixed-term contracts attractive: no severance discussion, no notice period, the relationship just concludes.

There are important carve-outs, however, that apply even to genuine fixed-term employees:

• If the term is longer than 12 months and the contract expires, ESA notice obligations are triggered.
• If the employee keeps working for three months or more after the contract has expired, the ESA treats them as if they had been employed for an indefinite term, and statutory notice entitlements apply.

These ESA traps catch employers who let a contract lapse without renewing it on paper or who casually extend an arrangement past its end date. The defined term only protects the employer if it is respected and documented.

What Is an Indefinite-Term Employment Contract?

An indefinite-term contract, often called a permanent contract, has no fixed end date. The relationship continues until either party ends it. When an employer ends an indefinite contract without cause, it must provide either working notice or pay in lieu of notice.

The amount owed depends on what the contract says. If the contract contains a valid, ESA-compliant termination clause, the employer's exposure can be limited to the statutory minimums or to a defined formula. If there is no enforceable termination clause, the employee is entitled to common law reasonable notice, which is usually far more generous than the ESA minimum and is assessed based on factors such as age, length of service, position, and the availability of similar work.

The key practical difference is flexibility. With an indefinite contract, the employer can end the relationship at any time and the cost is, at least in principle, capped or predictable. There is no remaining "term" to pay out. As the cases below show, that distinction can be worth six figures.

The Hidden Liability in a Fixed-Term Contract Ontario Employers Miss

The single most important risk in any fixed term contract in Ontario is what happens when the employer wants out before the end date. This is the issue that the Court of Appeal for Ontario settled in Howard v. Benson Group Inc., 2016 ONCA 256.

John Howard was hired on a five-year fixed-term contract. The employer terminated him without cause after about 23 months. The contract contained a termination clause, but it was unenforceable. The Court held that where a fixed-term contract is ended early and there is no enforceable early-termination provision, the employee is entitled to the wages and benefits they would have earned over the entire remaining term. Critically, the Court found there is no duty to mitigate. The employee does not have to look for another job to reduce the employer's bill, and any money they do earn elsewhere does not reduce what the employer owes.

The Court reasoned that imposing a duty to mitigate would undermine the certainty the parties bargained for when they chose a fixed-term arrangement. As the decision put it, if parties want to modify that obligation, they must say so unambiguously in the contract. For Howard, what might have been a few months of common law reasonable notice instead became a payout covering roughly the remaining three years of his contract.

What this looks like in dollars

Consider an employee hired on a two-year contract at $80,000 per year and terminated without cause at the six-month mark. There are 18 months left on the term. Without an enforceable early-termination clause, the employer owes the value of those 18 months of salary, roughly $120,000, plus the value of benefits and any other compensation over that period. And because there is no duty to mitigate, the employer pays that full amount even if the employee lands a new job the following week.

Compare that to an indefinite-term employee in the same role. With a valid termination clause limiting entitlement to, say, ESA minimums, the cost on termination at six months might be one or two weeks of pay. Even with no clause and only common law reasonable notice, the figure would typically be assessed on length of service and other factors, and it would be reduced by whatever the employee earns elsewhere during the notice period. The fixed-term structure, intended to add certainty, has multiplied the employer's exposure.

A termination clause is not automatic protection

Employers sometimes assume that adding an early-termination clause to a fixed-term contract neutralizes this risk. It only does so if the clause is fully ESA-compliant. If it is not, it is void, and the employer is back to owing the full remaining term.

This is the lesson of Dufault v. Municipality of Ignace (2024 ONCA 915). Karen Dufault was hired as a youth engagement coordinator on a three-year fixed-term contract and was terminated without cause before completing her first year. Her "for cause" termination clause defined cause more broadly than the ESA's "wilful misconduct" standard, which made it non-compliant. Following the principle in Waksdale v. Swegon North America Inc., 2020 ONCA 391, that a single defective provision can void the entire termination scheme, the unenforceable "for cause" language took down the "without cause" language with it. The clause provided no protection, and the employee was awarded the value of the remaining term, approximately $157,000. The Supreme Court of Canada declined to hear a further appeal in June 2025, leaving the result in place.

The takeaway is blunt. A boilerplate termination clause in a fixed-term contract does not cap liability. If anything is wrong with it, the fixed-term obligation springs back to life in full.

The Auto-Renewal and Rolling Renewal Trap

A second danger lurks in renewal mechanics. Many fixed-term contracts contain an automatic renewal clause: the contract renews for another full term unless one party gives notice to opt out by a deadline. If the employer forgets to send that notice, the contract renews, and a fresh full term of fixed-term liability attaches.

The compounding effect is what makes this so costly. A one-year contract that auto-renews twice because the opt-out deadline was missed is now, in effect, a three-year commitment. If the employer then wants to end the relationship early, the Howard v. Benson rule applies to the full renewed term. Courts have treated unambiguous auto-renewal language as binding and required employers to pay out the renewed term. Missing an internal calendar reminder is not a legal defence.

Employers who use auto-renewing fixed-term contracts need a reliable system for tracking opt-out windows, and they should understand that every missed deadline can add another full term of no-mitigation liability.

The Successive-Renewals Trap: When Fixed-Term Becomes Indefinite

The third trap is more subtle and arguably the most dangerous, because it can convert a series of short contracts into the exact open-ended relationship the employer was trying to avoid.

In Ceccol v. Ontario Gymnastic Federation, 2001 CanLII 8589 (ON CA), an employee worked for roughly 16 years under a series of one-year contracts that were renewed annually. When the relationship ended, the employer argued it owed only the remaining value of the latest one-year term. The Court of Appeal disagreed. It looked past the labels to the substance of the relationship and found the employment was effectively indefinite. The employee was entitled to common law reasonable notice based on her full length of service, and the trial court's award of 16 months' notice reflected that length of service, though the amount was reduced on appeal to account for the employee's failure to mitigate.

Several factors push a string of fixed-term contracts toward being treated as indefinite employment:

• Employer statements, written or verbal, suggesting continued or ongoing employment
• Contracts that roll over without genuine renegotiation or fresh signatures
• A position that is operational and ongoing rather than tied to a discrete project
• An employee performing core, permanent business functions rather than a finite task

The good news for employers is that this outcome is avoidable. In Steele v. The Corporation of the City of Barrie, 2022 ONSC 7245, the court found that successive renewals over roughly 3.5 years did not create indefinite employment. The difference was documentation. Each extension was clearly and unambiguously marked as temporary with a defined end date, there were no representations of continuing employment, and the renewal notices left no room for ambiguity. Steele shows that fixed-term status can be preserved across multiple renewals, but only with disciplined, consistent paperwork at every step.

When a Fixed-Term Contract Actually Makes Sense

None of this means fixed-term contracts are never appropriate. Used in the right situations, with the right drafting, they are a legitimate tool. They make the most sense when the work itself has a genuine, definable end point.

Common defensible uses include:

• Parental or other leave coverage, where someone is hired to fill in for an employee who is away. The contract should be tied to the specific leave rather than a hard calendar date, because leaves can be extended and a mismatched end date creates risk.
• True project-based work with a defined deliverable and timeline, such as a construction project, a software implementation, or an audit engagement. The scope and end point should be documented.
• Seasonal roles where the season is genuinely defined.
• Grant-funded positions where the funding has a fixed end date.

What separates a defensible fixed-term contract from a risky one is whether the temporary nature is real and well documented. The role should not exist independently of the leave or project it is tied to. The job posting and offer letter should describe the position as temporary. There should be no promises of renewal or continuing work. And if an extension is genuinely needed, it should be documented clearly as a further period of temporary work, in the disciplined manner Steele rewards.

The Safer Default: Indefinite-Term with a Well-Drafted Termination Clause

For most Ontario employers, an indefinite-term contract with a valid, ESA-compliant termination clause is the lower-risk choice. It gives the employer a capped, predictable cost of exit instead of an obligation to pay out the remainder of a multi-year commitment.

A properly drafted termination clause displaces common law reasonable notice and limits the employer's exposure to the ESA minimums or another defined, lawful formula. The employer can end the relationship at any time without owing a remaining "term," and the duty to mitigate applies, so an employee who finds new work quickly reduces the amount owed. Each of these features cuts the other way under a fixed-term contract.

The catch is that the termination clause must actually comply with the ESA. After Waksdale and Dufault, Ontario courts apply that requirement strictly:

• The "for cause" language must track the ESA standard, generally described as "wilful misconduct, disobedience or wilful neglect of duty that is not trivial and has not been condoned," and must not sweep in lesser conduct such as ordinary poor performance.
• The "without cause" provision must guarantee at least the ESA minimum notice or pay in lieu, plus any statutory severance owed.
• A single non-compliant provision can void the entire termination scheme, even the parts that would have been fine on their own.
• Generic saving clauses that say the provision should be read to comply with the ESA have been rejected by Ontario courts and will not rescue an otherwise defective clause.

Because the law in this area has shifted materially since 2020, termination clauses written even a few years ago may no longer be enforceable. Ontario's Working for Workers Acts have also amended several employment standards that interact with contract drafting, which is one more reason to revisit older agreements. You can read our analysis of the Working for Workers Acts for a fuller picture of those changes. Employment contracts also frequently bundle in restrictive covenants, and Ontario now prohibits most non-competes under the ESA, so it is worth reviewing our guide to non-compete clauses alongside any termination-clause update. Reviewing contracts on a regular basis is not housekeeping. It is risk management.

Quick Comparison: Fixed-Term vs. Indefinite for Ontario Employers

The rule of thumb is straightforward. For most employers, an indefinite-term contract with a rigorously drafted and regularly updated termination clause offers more flexibility and less financial exposure than a fixed-term contract that lacks airtight early-exit language.

Frequently Asked Questions

What happens if an employer ends a fixed-term contract early in Ontario?

If the contract has no enforceable early-termination clause, the employer generally owes the employee the wages and benefits for the full remaining term under Howard v. Benson Group Inc., 2016 ONCA 256. There is no duty to mitigate, so the employee keeps the full amount even if they find new work.

Do fixed-term employees in Ontario get severance pay?

At natural expiry of a genuine fixed-term contract, no statutory termination pay is owed, pursuant to the exemption in Ontario Regulation 288/01 under the ESA. However, if the term exceeds 12 months, or the employee continues working three or more months past expiry, ESA notice and severance entitlements can apply. Early termination without a valid clause triggers far larger liability.

Can a series of fixed-term contracts turn into indefinite employment?

Yes. As in Ceccol v. Ontario Gymnastic Federation, courts look past the contract label to the real nature of the relationship. Repeated renewals, promises of continued work, and ongoing operational duties can lead a court to find indefinite employment and award common law notice based on total service.

What makes a termination clause unenforceable in Ontario?

A termination clause is void if any part of it falls below ESA standards. A common defect, seen in Dufault v. Municipality of Ignace, is a "for cause" provision that defines cause more broadly than the ESA's wilful misconduct standard. Under Waksdale, one defective provision can invalidate the entire termination scheme.

Is a fixed-term or a permanent contract better for Ontario employers?

For ongoing roles, an indefinite (permanent) contract with a valid termination clause is usually safer because it caps the cost of exit and preserves the duty to mitigate. Fixed-term contracts make sense for genuine projects, leave coverage, or defined seasons, provided they are drafted and documented carefully.
