Probationary Period & Employment Law Explained
What Is a Probation Period in Ontario?
A probation period is a defined initial period of employment during which an employer may assess an employee’s suitability for the role.
In Ontario, there is no automatic probation period under employment law. A probationary period only applies if it is clearly written into the employment contract through a valid probation clause.
Without a properly drafted probation clause, normal termination rules apply from day one.
Is a 3-Month Probationary Period Mandatory in Ontario?
No. Ontario employment law does not automatically create a 3-month probationary period.
The Employment Standards Act, 2000 (ESA) simply states that employees with less than three months of service are not entitled to statutory notice of termination. That is different from a contractual probation period.
A probationary period must be expressly written into the employment contract to be enforceable.
What Is a Probation Clause in an Employment Contract?
A probation clause is a term in an employment agreement that allows an employer to terminate employment during the probationary period based on suitability rather than just cause.
To be enforceable, a probation clause must:
- Be clearly written and unambiguous
- Comply with minimum standards under the ESA
- Not contract out of statutory rights after three months
Ambiguous or poorly drafted probation clauses may be unenforceable.
Termination During the Probationary Period
During a properly drafted probationary period, the standard for termination is “suitability” rather than “just cause.”
Suitability may involve:
- Performance
- Skills and capability
- Cultural fit
- Ability to meet expectations
However, employers must still:
- Act in good faith
- Provide a fair opportunity to demonstrate suitability
- Avoid discriminatory or human rights violations
Probation does not eliminate legal protections.
What Happens After Three Months?
Under the ESA:
- Employees with three months of service are generally entitled to statutory notice or pay in lieu.
- If the probation period extends beyond 90 days, statutory minimums apply.
Even during probation, contractual rights and human rights protections remain in force.
Can an Employer Extend the Probationary Period?
Yes, but only if the employment contract allows it.
If the contract does not permit extension, attempting to extend probation may risk constructive dismissal.
Extensions must be:
- Expressly allowed in the agreement
- Implemented in good faith
- Compliant with ESA minimum standards
Employers should obtain legal advice before extending or terminating during probation.
Probation Employment Law: Key Legal Principles
Under Ontario employment law:
- There is no automatic probationary period
- A probation clause must be clearly drafted
- Termination standards are lower but not unlimited
- Human rights protections always apply
- ESA minimums apply after three months
Many disputes arise from unclear employment contracts or improperly drafted probation clauses.

For Employees: What You Should Know
If you were terminated during probation:
- Review your employment contract carefully
- Confirm whether a valid probation clause exists
- Assess whether the employer acted in good faith
- Consider whether discrimination or reprisal occurred
Probation does not eliminate your legal rights.
For Employers: Reducing Legal Risk
To reduce exposure:
- Draft clear probation clauses
- Conduct documented performance reviews
- Provide feedback and opportunity to improve
- Avoid vague or overly broad language
- Seek legal advice before termination
Improperly drafted probation clauses are frequently struck down by courts.
A probation period is a contractual trial period at the start of employment allowing an employer to assess suitability before full employment protections apply.
No. A probationary period only exists if it is written into the employment contract.
If a valid probation clause exists and the employee has less than three months of service, statutory notice may not be required. However, employers must still act in good faith and comply with human rights laws.
A probation clause may be unenforceable if it is unclear, ambiguous, or violates minimum employment standards under the ESA.
As Christopher Achkar, employment lawyer and founder of Achkar Law, explains:
“A poorly defined probation period can expose your business to unnecessary legal risk. Before hiring or terminating during probation, speak to a lawyer to ensure your employment contracts and practices are legally sound.”
