In the world of corporate risk management, the fixed-term employment contract is frequently the ultimate wolf in sheep’s clothing. For decades, sophisticated employers in Ontario, particularly in the tech, medical, and executive sectors, used these agreements as a perceived shield, believing that a defined end date provides a clean, cost-free exit strategy.
The reality, forged by a series of punishing court decisions from Waksdale v. Swegon North America Inc. to the recent Dufault v. The Corporation of the Township of Ignace, is that fixed-term contracts have become the single most dangerous instrument in an employer’s drafting toolkit. Far from limiting liability, they often act as a multiplier, exposing organizations to damages that far exceed the common law standard of reasonable notice. The “certainty” they promise is a legal mirage.
For general counsel and human resources executives, the continued use of these agreements without a rigorous, specialized legal audit is a gamble with diminishing odds.
This blog explores the ten structural failures that make fixed-term contracts a liability trap in the current Ontario legal landscape.
1. The “Balance of Term” Guillotine
The most lethal feature of a fixed-term contract is the penalty for early termination. Under Ontario common law, if an employer terminates a fixed-term employee before the end date without a valid, enforceable early termination clause, the employee is entitled to the wages they would have earned for the remainder of the term.
This is not “reasonable notice.” It is a contractual debt. If you hire an executive on a five-year fixed term and fire them after six months, and your termination clause is found void (see point #3), you do not owe them reasonable notice (perhaps 4-6 months). You owe them 4.5 years of salary. This distinct legal mechanism can turn a routine dismissal into a million-dollar liability overnight.
2. The Dufault Expansion of “Just Cause” flaws
The 2024 decision in Dufault significantly tightened the screws on fixed-term contracts. The Ontario Superior Court, and subsequently the Court of Appeal, scrutinized “for cause” termination provisions with unprecedented rigour.
The court found that a termination clause allowing dismissal “for cause” was unenforceable because it did not explicitly align with the Employment Standards Act (ESA) standard of “wilful misconduct.” In a fixed-term context, this is catastrophic. If the “for cause” clause is void, the “without cause” clause often falls with it (the Waksdale principle). As a result, the employer loses the right to terminate early, triggering the “balance of term” payout described above.
3. The “At Any Time” Trap
A standard phrase in legal drafting for decades has been that the employer may terminate the engagement “at any time” or “at its sole discretion.” In the context of Dufault, this language has been weaponized against employers.
Courts are increasingly finding that the phrase “at any time” implies a right to terminate during a protected leave (such as sick leave or pregnancy leave) or in reprisal for exercising statutory rights, which is prohibited by the ESA. Even if the employer never intended to act illegally, the mere theoretical possibility that the contract permits it renders the termination clause void ab initio. In a fixed-term contract, this void clause serves as the trigger for balance-of-term damages.
4. The Mitigation Exemption
In a standard wrongful dismissal case, the employee has a duty to mitigate their damages by seeking new employment. Any income they earn during the notice period is deducted from what the employer owes. This is a crucial cost-saving mechanism for employers.
Fixed-term contracts typically extinguish this duty. If a court awards the balance of the term, it is considered “liquidated damages,” not pay in lieu of notice. Consequently, the employee can walk out of your office, start a higher-paying job the next morning, and still collect every dollar remaining on their contract with you. The concept of “double recovery” is permissible here, making the financial exposure for the employer absolute and irreducible.
5. The Substratum Doctrine
The risk does not end when the contract date arrives. If an employee continues to work past the end date of a fixed-term contract without a new written agreement, the law presumes the parties have entered into a contract of “indefinite duration.”
However, a dangerous nuance known as the “substratum doctrine” applies. If the employee’s duties have evolved significantly over the course of renewed fixed-term contracts, a court may find that the “substratum” (or foundation) of the original written agreement has disappeared. When this happens, the restrictive termination clauses in the old contract (which capped severance) are discarded, and the employee is entitled to full common law reasonable notice, often calculated based on their entire tenure, not just the most recent term.
6. The Problem of Consecutive Renewals
Employers often try to mitigate risk by using short, renewable fixed-term contracts (e.g., a series of one-year agreements). This practice creates a vulnerability under the ESA.
If an employer continuously renews a fixed-term contract for years, a court may look past the paper labels and find that the relationship is, in substance, indefinite. This is particularly true if the work is integral to the organization and not truly temporary in nature (like a project or maternity cover). Once the court deems the relationship “indefinite,” the employer’s reliance on the fixed end date evaporates, and they are back to owing common law reasonable notice, often with a “bump” in damages for having attempted to evade statutory obligations through artificial contract structures.
7. The Parental Leave Complexity
Fixed-term contracts often fail when they overlap with statutory leaves. If an employee on a one-year fixed term goes on parental leave in month eight, the employer faces a dilemma.
Strictly speaking, the contract expires during the leave. However, terminating the employment relationship (even by simply letting the contract expire) while the employee is on protected leave carries a high risk of a human rights discrimination claim. The employee may argue that, but for their leave, the contract would have been renewed. The employer must then prove that the decision not to renew the contract was entirely independent of the employee’s leave. Given a history of renewals for other employees, this represents a significant evidentiary challenge for the employer to overcome.
8. The “Notice of Non-Renewal” Ambiguity
A common drafting error concerns the notice required to terminate a contract at its scheduled expiration date. Some contracts omit this requirement, while others specifically mandate “30 days’ notice of renewal or non-renewal.”
A significant problem arises from administrative failures, such as neglecting to issue the required 30-day non-renewal notice before the contract concludes. This oversight can lead to the automatic renewal of the contract for another full term or its conversion into an indefinite agreement. Consequently, an employer who intends to terminate an employee may inadvertently become obligated to make additional salary payments for another year.
9. The Loss of Probationary Power
Probationary periods are conceptually at odds with fixed-term contracts. While you can draft a probation clause into a fixed-term agreement, enforcing it is legally perilous.
To terminate a fixed-term employee during probation, the clause must be drafted with extreme precision to override the “balance of term” presumption. If the probation clause is found to be ambiguous or non-compliant with the ESA (a common occurrence regarding the lack of statutory notice pay during probation), it is struck down. The employer is then left trying to fire an employee three months into a two-year contract, only to find they owe the remaining 21 months of salary because the probationary exit hatch was welded shut by a drafting error.
10. The Inflexibility of Performance Management
Finally, fixed-term contracts handcuff an employer’s ability to manage a changing workforce. In an indefinite relationship, an employer can restructure, layoff, or repackage a role with relative ease, provided they pay the appropriate severance.
In a fixed-term employment agreement, “restructuring” does not constitute a legally justifiable ground for termination. Absent an impeccably drafted early termination provision within the agreement (a feature that is increasingly uncommon under current case law, as previously stated), the employer remains bound. Consequently, an employer cannot dismiss the employee due to adverse economic conditions without fulfilling the financial obligations of the contract. The fixed term transforms labour expenditure from a variable operating cost into a fixed debt liability, thereby compromising the operational flexibility requisite in an unstable economic environment.
Protecting Your Organization from Termination Liability
The fixed-term contract is a relic of a less litigious era. While they still serve a narrow purpose for genuine, short-term project work or leave coverage, their use as a general retention strategy is legally negligent in 2025. The interplay between Dufault, the Employment Standards Act, and the “balance of term” principle creates a liability profile that is unacceptable for most modern organizations.
For the sophisticated employer, the move to indefinite contracts with enforceable, ESA-compliant termination clauses is the only viable path to predictable risk management. It is far better to owe a known quantity of severance than to gamble on a “fixed” date that the courts can erase with the stroke of a pen.
