Probation periods in Ontario explained
What “probation” really means
Probation is a contract term, not an automatic rule. You’re only “on probation” if your signed offer or employment agreement says so.
The ESA still protects you. After 3 months of continuous employment, the Employment Standards Act, 2000 (ESA) requires notice or termination pay, even if you’re on probation—unless the employer proves wilful misconduct (a high bar, narrower than “just cause”).
Human rights still apply. Probation doesn’t erase protections under the Ontario Human Rights Code. If disability, family status, pregnancy, religion, or another protected ground is in play, the employer must consider accommodation.
Why probation matters for you
A valid probation clause lets the employer end employment for unsuitability during the probation window with less notice than you might otherwise receive at common law. But that clause has to be drafted and used properly—and that’s where many employers slip up.
When probation clauses become weak or invalid (your leverage)
No probation term in your contract. If your agreement doesn’t mention probation, you’re not on probation by default.
Added after you started, with no new consideration. Employers can’t usually bolt on a probation clause mid-employment without giving you something of real value in exchange.
ESA-offside wording. Any clause that tries to allow termination “at any time without notice” after 3 months—or that cuts off ESA minimums for anything less than wilful misconduct—is vulnerable. If one termination sub-clause breaches the ESA, courts can toss all the termination provisions (the “Waksdale” problem), putting you back into common-law notice.
Ambiguous or confusing drafting. If a clause could operate illegally in some scenarios, courts tend to read it against the drafter. “Saving clauses” rarely rescue bad wording.
Unilateral or open-ended extensions. Employers can’t usually extend probation unless the contract clearly allows it and sets limits. Indefinite or retroactive extensions are risky.
Extending because of a protected leave or needing accommodation. Employers should handle ESA-protected leaves and accommodation needs carefully. Extending probation because of a protected ground can be discriminatory.
No real suitability assessment or bad-faith process. Even in probation, employers are expected to assess suitability in good faith—with real feedback, a fair chance to improve, and consistent reasons.
Your rights and entitlements at key moments
First 3 months: The ESA doesn’t require notice or termination pay (still, human-rights and reprisal protections apply). If your contract has no probation clause or your termination clause is invalid, you may still have common-law notice rights.
After 3 months: ESA notice or termination pay is owed unless the employer proves wilful misconduct. “Poor performance” or “not a fit” usually isn’t enough to deny ESA minimums.
During probation with a valid clause: You can still ask for coaching, feedback, and accommodation. Document everything.
Red flags to watch for in offers and policies
“Zero notice during probation” without mentioning the ESA after 3 months.
“Cause” defined more broadly than wilful misconduct for ESA purposes.
Vague language about extending probation “as needed” with no limits.
Policies that quietly expand or contradict your signed contract.
What to do if you’re put on probation
Get your paperwork. Ask for the signed offer/contract, any policy it references, and any probation or termination language.
Ask for specifics. What does “unsuitable” mean here? What targets, training, or support are expected? Get it in writing.
Document your side. Keep a weekly log: feedback received, tasks completed, metrics hit, roadblocks flagged, help requested.
Raise accommodation early (if needed). Share functional limitations (not diagnosis) and propose realistic adjustments.
Push back—politely—on unfair extensions. If the contract doesn’t allow an extension, or the reason relates to protected grounds, say so in writing.
If you’re terminated during or after probation
Don’t sign on the spot. Ask for the termination letter, the contract, and time to review.
Check the calendar. Are you past 3 months? If yes, ESA notice or termination pay is likely owed unless wilful misconduct is proven.
Scrutinize the clause. If the probation or termination wording breaches the ESA or is unclear, you may be entitled to common-law notice (often more than the ESA minimums).
Consider human rights. If the timing suggests discrimination (e.g., after disclosing a disability or pregnancy), get advice immediately.
Negotiate. Use defects in the clause, process, or timing as leverage for more pay, benefits continuation, and a neutral reference.
Quick FAQ
Do I have to be told I’m on probation?
Yes—probation must be in your signed contract. If you never agreed to it, you may not be on probation.
Can they extend probation?
Only if the contract clearly allows it and the extension is reasonable and documented. Even then, ESA rules after 3 months still apply.
What if I’m still within the first 3 months?
You may not get ESA notice, but you still have human-rights protections. And if your contract’s termination language is invalid, you might have common-law notice rights.
What if I took a leave during probation?
Employers sometimes try to “pause” probation for absences or ESA-protected leaves. Whether that’s allowed usually depends on your contract and the reason for the absence. Push for clarity in writing.
