Ontario Termination Requirements for Employers: The 2026 Risk Guide
Protect your business from wrongful dismissal claims, ESA violations, and the “Common Law Trap.”
The “Ontario Termination Trap” (What the Gov Site Doesn’t Tell You)
In Ontario, meeting the Employment Standards Act (ESA) minimums is rarely enough. Most small businesses (1–50 staff) are sued not because they broke the ESA, but because they ignored Common Law entitlements.
The Risk:
Without a bulletproof employment contract, a 5-year employee might be entitled to 4 months of pay, even if the ESA says only 5 weeks.
Terminating an employee in Ontario isn’t just an HR task—it’s a legal decision with real financial risk.
If you get notice, severance, or documentation wrong, it can quickly turn into a wrongful dismissal claim costing thousands (or more).
This page breaks down what you need to know—and when it makes sense to get expert support.
Minimum Notice Requirements (ESA)
If you are terminating without cause, you must provide notice or pay-in-lieu based on length of service:
| Years of Service | ESA Minimum Notice | The "Common Law" Reality |
|---|---|---|
| Less than 1 Year | 1 Week | Can be 1–3 months |
| 1 – 3 Years | 2 Weeks | Can be 3–6 months |
| 5 – 10 Years | 1 week per year (max 8) | Can be 12+ months |
Pro-Tip: If your employment contracts haven’t been updated since the Waksdale ruling, your “Termination Clause” is likely unenforceable. You could be on the hook for the “Common Law” column above.
Before You Terminate: What You Need to Know
In Ontario, termination is governed by:Employment Standards Act (ESA) Common law obligations Human rights considerations
Employment Standards Act (ESA)
Common law obligations
Human rights considerations
Meeting ESA minimums alone is often NOT enough.
Many employers unknowingly underpay or mishandle terminations—this is where risk comes in.
Severance Pay (When It Applies)
Many Ontario employers confuse these two. Severance is an additional payment required if:
Your global payroll is $2.5 Million or more,
You are part of a mass layoff (50+ employees).
Calculation:
1 week of regular wages for every year of service (up to 26 weeks).
The Biggest Risk: Common Law Entitlements
Here’s where most employers get caught:
Even if you meet ESA minimums, employees may still be entitled to significantly more compensation under common law—unless you have a properly drafted employment contract.
This is often the difference between:
- Paying a few weeks
vs - Paying several months
Landmark Ontario Termination Cases Every Employer Should Know
Waksdale v. Swegon North America Inc. — The “Termination Clause Trap”
This case changed everything for employment contracts in Ontario.
What happened:
The employer had a termination clause that partly violated the ESA—even though the rest of the clause was compliant.
Court decision:
The entire termination clause was thrown out.
Why it matters:
Even a small drafting error can void your contract completely—exposing you to full common law notice (months of pay instead of weeks).
Employer takeaway:
If your contracts haven’t been updated recently, they may be unenforceable right now.
Bardal v. Globe & Mail Ltd. — The Foundation of Common Law Notice
This is the case courts still rely on today to determine notice periods.
What it established:
There’s no fixed formula. Courts look at:
- Age
- Length of service
- Position/seniority
- Availability of similar employment
Why it matters:
Two employees with the same tenure can get very different severance outcomes.
Employer takeaway:
There is no “safe shortcut.” Each termination must be assessed individually.
McKinley v. BC Tel — The “Just Cause” Reality Check
Employers often think misconduct = no severance.
Court decision:
Not all misconduct justifies termination without notice. It must be serious and proportional.
Why it matters:
Poor performance, minor policy breaches, or attitude issues rarely meet the legal threshold.
Employer takeaway:
Claiming “just cause” without strong evidence is one of the fastest ways to trigger a lawsuit.
Top 5 Mistakes That Lead to Ministry of Labour Complaints
1. The “Just Cause” Myth:
Thinking you don’t have to pay because they “performed poorly.” (In Ontario, the bar for “Wilful Misconduct” is extremely high).
2. Misclassifying Contractors:
If they work only for you, they are likely employees entitled to full notice.
3. Ignoring Human Rights:
Terminating while someone is on sick leave, parental leave, or disability.
4. Incomplete Final Pay:
Forgetting to include accrued vacation pay or commissions in the final check.
5. Using “Google or AI Generated Templates”:
Generic letters often lack the specific Ontario-mandated language to make a release binding.
When Should You Get Help?
- The employee is long-tenured or senior
- You don’t have a clear employment contract
- There’s risk of conflict or complaint
- You’re unsure about severance or notice
