Ontario Employment Contract: Termination Clauses, Probation & ESA Minimums

Post-Waksdale termination clause drafting, ESA minimum entitlements table, probation period rules, fixed-term traps, and restrictive covenant enforceability.

Updated June 2025

Ontario employment contracts are among the most consequential commercial documents a business signs — and the most frequently litigated. The Supreme Court's validation of the Waksdale approach means that a single defective clause can unwind an employer's entire notice limitation strategy, exposing the employer to common law reasonable notice for the full employment period. This guide covers what employment lawyers review in every employment agreement.

The Waksdale Problem: Why Termination Clauses Fail

Waksdale v. Swegon North America Inc. (2020 ONCA 391)

The Ontario Court of Appeal held that the enforceability of a termination clause must be assessed holistically — not part by part. If any portion of the termination provision (including a just-cause clause that is never invoked) purports to contract out of the ESA, the entire termination provision is void. The result: the employee is entitled to common law reasonable notice, not the contractual notice period. This decision invalidated thousands of employment contracts that had been considered enforceable.

5 Common Termination Clause Defects

Just cause with no notice

Problem

Using 'cause' as defined in the contract (e.g., 'serious misconduct') rather than the ESA's narrower 'wilful misconduct' standard — Waksdale makes the entire termination provision void

Best Practice

Specify that 'cause' for no-notice termination means 'wilful misconduct, disobedience or wilful neglect of duty that is not trivial and has not been condoned' — tracking ESA language exactly

Limiting termination pay to ESA minimum

Problem

Language like 'we will provide ESA minimums only' — enforceable to displace common law if validly drafted, but any other defect in the termination clause voids the entire provision

Best Practice

Include a severability clause specifically for termination pay: 'If any part of this termination provision is unenforceable, the minimum ESA entitlement shall apply' — courts have been skeptical but some post-Waksdale decisions accept this

Benefit continuation exclusion

Problem

Failing to address benefit continuation during the notice period — ESA requires continuation of benefits for the statutory notice period

Best Practice

Expressly state that benefits will be maintained during any statutory notice period and either continued or paid in lieu during any contractual notice period

Lump sum in lieu of notice

Problem

Paying a lump sum 'in full satisfaction of all amounts owing' — may attempt to include severance pay in a termination pay clause, violating ESA

Best Practice

Clearly separate and identify termination pay and severance pay components; do not bundle them or purport to satisfy severance in the termination clause

Variable or incentive pay

Problem

Excluding bonus or commission from notice period pay calculation — Paquette v. TeraGo (2016 ONCA) requires continued accrual of variable compensation during reasonable notice period

Best Practice

Address variable pay in the termination clause or at minimum in the bonus/commission plan; specify whether it continues during notice or is subject to active employment requirements

*Severance pay applies only where employer's Ontario payroll is $2.5M+ or the employee was laid off as part of a mass lay-off (50+ employees). Severance pay is in addition to termination pay.

Common law notice is almost always higher than ESA minimums. The Bardal factors (character of employment, length of service, age, availability of similar employment) typically yield 1 month per year of service as a rough benchmark — but can be higher for senior employees. ESA minimums are the floor only.

Probation Periods in Ontario

ESA probation
3 months — employees with less than 3 months service have no ESA entitlement to notice or termination pay. ESA cannot be contracted out of to create a longer probation period.
Contractual probation
Employer and employee can agree on a probationary period for performance assessment purposes, typically 3-6 months. Failure during contractual probation triggers ESA minimums if over 3 months service.
Common law during probation
Even during probation, common law reasonable notice applies unless validly contracted out. The probationary period is a factor — but not absolute — in assessing reasonableness.
Dismissal for failure to meet standards
To dismiss for failure to meet probationary standards without triggering a performance-based termination claim, employers must communicate the standards and give the employee a fair chance to meet them.

Fixed-Term Contract Traps

Howard v. Benson Group (2016 ONCA): An employee dismissed before the end of a fixed-term contract is entitled to the wages for the remainder of the contract — no mitigation duty, no Bardal analysis. If a fixed-term contract does not include a valid early termination clause, the full remainder of the contract is payable. For long fixed-term contracts (2+ years), this can be catastrophically expensive.

  • Always include a valid early termination clause in fixed-term contracts
  • Post-Waksdale, the early termination clause in a fixed-term contract faces the same scrutiny as in indefinite-term contracts
  • Automatic renewal clauses can convert a fixed-term contract into an indefinite-term contract — specify what happens on expiry
  • Maximum term employment (e.g., 'up to 12 months') may still be treated as indefinite-term depending on drafting
  • If you roll over the same employee on successive fixed-term contracts, courts may treat the relationship as indefinite-term

Non-CompeteProhibited (s. 67.2 ESA) for most employees since Oct 25, 2021Business sale context; executives (C-suite) — still enforceable if reasonableVoid and unenforceable for employees covered by the ESA prohibition

Frequently Asked Questions

What makes a termination clause unenforceable in Ontario?

Post-Waksdale v. Swegon (2020 ONCA), a termination clause is void in its entirety if any part of it — including the just cause provision — attempts to contract out of ESA minimums, even if other parts appear valid. Courts read the entire termination provision holistically. Common defects: clauses that allow termination for cause with no notice but use 'cause' more broadly than the ESA's 'wilful misconduct' standard; clauses that purport to limit severance pay below ESA entitlements; and clauses that exclude benefit continuation.

What is the probation period under Ontario's Employment Standards Act?

The ESA provides that employees with less than 3 months of service are not entitled to notice of termination or termination pay under the ESA. This effectively creates a 3-month probationary period for ESA purposes. However, common law notice rights still apply during this period unless validly contracted out. A contractual probation period longer than 3 months does not extend the ESA exemption — ESA minimums apply once an employee hits 3 months of service regardless of what the contract says.

Are non-compete clauses enforceable in Ontario employment contracts?

Effective October 25, 2021, the Employment Standards Act was amended to prohibit non-compete agreements in most employment contracts (s. 67.2 ESA). The prohibition does not apply to agreements entered into in connection with the sale of a business where the seller becomes an employee of the buyer, or to executive-level employees (C-suite). Non-solicitation of clients and employees clauses remain enforceable if reasonable in scope.

What are the minimum ESA entitlements on termination in Ontario?

ESA termination pay: 1 week per year of service, up to 8 weeks (for employees with 3+ months service). ESA severance pay (additional, for employees with 5+ years and employer payroll of $2.5M+): 1 week per year of service, up to 26 weeks. Benefit continuation during the notice period. These are minimums only — common law reasonable notice is typically much higher and applies unless validly contracted out.
