Short Service Employees Explained (Ontario)
Ontario employers often assume that terminating a short-service employee, also referred to as a short-service worker or short-term employee, carries minimal legal risk. That assumption is one of the most common (and expensive) employment law mistakes.
Short service does mean no rights, and in many cases, it does not mean minimal liability.
This article explains what a short service employee is, how Ontario law treats short service employment, and what employers need to know to manage risk under the Employment Standards Act (ESA), Human Rights Code, OHSA, and common law.
What Is a Short Service Employee?
A short-service employee is not a defined legal category under Ontario legislation. It is a practical term used to describe an employee with a brief period of service, typically measured in weeks or months rather than years.
In most employment law disputes, a short-service employee is someone with:
- Less than one year of service; or
- Less than three months where the ESA termination rules are at issue
Critical takeaway:
There is no automatic legal exemption for short-service employees.
🔎 Quick Fact
Ontario employment law protects employees from the very first day, regardless of their length of service.
As Christopher Achkar, employment lawyer and founder of Achkar Law, explains:
“Short service employees often have different entitlements than longer-term staff, but misunderstandings can still lead to legal disputes. Before making decisions that could affect rights or obligations, consult a lawyer to get clear, informed guidance.”
Why Short-Service Employees Create Serious Employer Risk
Short service employees frequently trigger disputes involving:
- Termination without notice assumptions
- Failed probationary dismissals
- Human rights claims during onboarding
- Workplace injury claims involving new workers
- Invalid termination clauses leading to common law exposure
Ontario courts have repeatedly warned employers that short service reduces risk, but does not eliminate it.
Employment Standards Act (ESA): Minimums Only
Statutory Notice Requirements
Under the Employment Standards Act, 2000 (ESA):
- Under 3 months of service → No statutory notice or pay in lieu required
- 3 months to less than 1 year → Minimum 1 week of notice or pay in lieu
These are minimum standards only.
🚩 Employer Risk Alert
ESA compliance does not protect you from common law notice claims unless your contract lawfully limits them.
Common Law Notice: Short Service Still Means Exposure
If a termination clause is invalid or missing, courts apply common law reasonable notice, even for short-term employees.
Courts rely on the Bardal factors, including:
- Length of service
- Age
- Nature of position
- Availability of comparable work
Ontario courts have consistently rejected the idea that short service automatically equals minimal notice.
Key Ontario Cases
- Minott v. O’Shanter Development Company Ltd. (1999 ONCA)
The Court confirmed that short service does not bar meaningful notice awards. - Love v. Acuity Investment Management Inc. (2011 ONSC)
A senior employee with just over two years’ service received 9 months’ notice, reinforcing that role and inducement matter. - Nagribianko v. Select Wine Merchants Ltd. (2017 ONCA)
The Court emphasized that recruitment and expectations can increase notice, even where service is brief.
✅ Best Practice for Employers
If you do not have a carefully drafted, ESA-compliant termination clause, short service will not protect you.
Probationary Employees Are Not Exempt Employees
A probationary employee is still an employee under Ontario law.
Key Principles for Employers
- Probation exists only by contract, not statute
Employers must:
- Assess suitability honestly
- Act in good faith
- Avoid arbitrary or discriminatory termination
Courts expect employers to meaningfully evaluate performance during probation, not use it as a liability shield.
A poorly drafted or poorly applied probation clause increases, not reduces, legal risk.
📌 Quick Tip
Probation that is not clearly written, applied, and documented can invalidate an employer’s defence in a wrongful dismissal claim.
Human Rights Obligations Apply From Day One
Under the Ontario Human Rights Code, protection begins immediately upon hire.
Short service provides no defence to discrimination claims involving:
- Disability and failure to accommodate
- Pregnancy or family status
- Race, creed, or gender
Ontario tribunals frequently award injury-to-dignity damages even when employment lasted weeks.
⚠️ Key Reminder
“Not a good fit” is not a defence when a protected ground is in issue.
Health & Safety: Short Service Increases Responsibility
Under the Occupational Health and Safety Act (OHSA), employers owe full safety duties to new and short-service workers.
New workers are statistically:
- More likely to be injured
- Less familiar with hazards
- More dependent on supervision
Failing to provide proper training, instruction, and supervision exposes employers to regulatory penalties and liability.
WSIA: Injury Risk Still Applies
Under the Workplace Safety and Insurance Act (WSIA):
- Short-service employees are fully covered
- Claims often involve onboarding failures
- Employer premiums and experience ratings may be affected
New-worker injuries are a known compliance focus for the WSIB and the Ministry of Labour.
Termination Clauses: The Most Common Failure Point
Many Ontario employers believe they are protected, until a court finds their termination clause unenforceable.
Common errors include:
- ESA non-compliance at any point in time
- Ambiguous or outdated language
- Improper interaction with benefits or severance
Once invalid, the employer is exposed to full common law notice, even for a short-term employee.
🚨 Executive Risk Summary
Short service + invalid termination clause
= unexpected wrongful dismissal liability
Best Practices for Ontario Employers
1. Use Modern, ESA-Compliant Agreements
- Draft clear termination and probation clauses
- Regularly audit templates
2. Train Managers on Early-Termination Risk
- Document performance concerns
- Avoid casual language
3. Take Onboarding Seriously
- Address accommodation immediately
- Complete safety training before work begins
4. Get Advice Before Terminating
Especially where:
- No contract exists
- The employee was recruited or induced
- Human rights issues are raised
When to Speak With an Employment Lawyer
You should seek legal advice if:
- You are terminating a short-service employee
- You are relying on probation
- Your termination clause has not been recently reviewed
- A discrimination issue is possible
Early advice often prevents litigation, rather than managing it after the fact.
