Recent Ontario case law is grappling with the interpretation of phrases such as “at any time,” “sole discretion” and “for any reason” in relation to an employer’s contractual right to limit an employee’s entitlement to common law notice. Notably, three decisions, Dufault v. The Corporation of the Township of Ignace, (“Dufault”), 2024 ONSC 1029, Baker v. Van Dolder's Home Team Inc., (“Baker”), 2025 ONSC 952, and most recently Chan v. NYX Capital Corp., (“Chan”), 2025 ONSC 4561, have cast doubt on the enforceability of termination clauses containing such language, suggesting that these phrases may render a clause void for contravening the Employment Standards Act, 2000 (the “ESA”).
In contrast, other recent decisions like Li v. Wayfair Canada ULC., (“Li”), 2025 ONSC 2959, and Jones v. Strides Toronto, (“Jones”), 2025 ONSC 2482, have adopted a different stance, holding that the inclusion of “at any time” does not automatically invalidate a termination clause.
This divergence has generated significant uncertainty in Ontario employment law. While the Court of Appeal has yet to provide definitive guidance, having dismissed the Dufault appeal on unrelated grounds, it is anticipated to weigh in on the issue in the Baker appeal. Until then, the most recent decision in Chan stands as the latest judicial voice highlighting concerns over such termination clause language, indicating continued uncertainty ahead.
Background: The Legal Landscape
Over the past several years, Ontario courts have scrutinized the language of termination clauses in employment contracts, particularly those that purport to allow termination “at any time” and “for any reason.” In Dufault, the Ontario Superior Court held that a termination clause reserving the employer’s right to terminate “at any time” and at its “sole discretion” was unlawful for breach of the ESA, reasoning that such language might allow termination during job-protected ESA leaves or after an ESA complaint. Baker followed Dufault, finding that the inclusion of “at any time” was enough to void the clause, even without reference to “sole discretion.”
In Chan, the Ontario Superior Court found a termination clause using “at any time” and “for any reason” to be unenforceable, following the reasoning in Dufault and Baker. The Court held that such language violated the ESA and further found the clause problematic because it released the employer from claims that cannot be contracted out of under the ESA and failed to define “cause” in accordance with the ESA standard. As a result, the Court awarded the plaintiff three months’ reasonable notice, despite the employer’s assertion that the employee was probationary.
However, other decisions have cast doubt on this analysis. In Li, the Ontario Superior Court upheld a termination clause with “at any time” and “for any reason” language, distinguishing Dufault on the basis that there were no flaws related to the definition of cause or the scope of termination payments. Similarly, in Jones, the Court held that “at any time” language, in the absence of “sole discretion,” does not contract out of the ESA, though the clause was found unenforceable for other reasons.
The ongoing division in the case law means that employers must exercise particular caution when drafting termination clauses. The Ontario Court of Appeal’s recent decision in De Castro v Arista Homes Limited, (“De Castro”), 2025 ONCA 260, further underscores the perils of imprecise drafting in employment contracts. In De Castro, the Court strictly scrutinized the termination clauses and found that any language permitting termination without notice in circumstances beyond those authorized by the ESA will render the clause unenforceable.
