Probation clauses in Ontario

Probation is one of the most widely misunderstood terms in Canadian employment. Many employers believe a probationary period means an employee can be dismissed freely, with no notice and no exposure, for some fixed opening stretch of the relationship. That belief is wrong in several directions at once, and acting on it is how straightforward hires turn into claims.

The reality is narrower and more procedural. A probationary period is a contractual arrangement that, when properly created and properly run, gives an employer a defined window to assess suitability against a standard that is more forgiving than just cause. It does not suspend employment standards legislation, it does not suspend human-rights protections, and it does not survive being run carelessly.

Probation is a contractual term, not an automatic right

There is no default probationary period in Ontario employment law. If your contract does not create one in writing, you do not have one. A probationary period exists only because the parties agreed to it before employment began — which means it must appear in a document the employee actually accepted before starting work, not in a handbook handed over on day one.

Timing is the detail that most often destroys the clause. An offer accepted verbally, followed by a written agreement signed after the employee has already started, raises the question of what the employee received in exchange for accepting terms they were not bound by. Get acceptance in writing before the first shift, and keep the record of when it happened.

The statutory floor still applies

Ontario’s Employment Standards Act sets a service threshold below which statutory notice is not owed. Employers often assume their probationary period and that threshold are the same length. There is no rule that makes them the same, and a probationary period drafted to run past the statutory threshold does not suspend the entitlement that has by then accrued. A clause purporting to do so risks being unenforceable in its entirety.

Human-rights protections apply from the first day regardless. A probationary dismissal that is connected to a disability, a pregnancy, a request for accommodation, or any other protected ground is exposed no matter how the clause is written.

The same is true of reprisal. An employee who raised a health-and-safety concern, asked about unpaid wages, or refused unsafe work is protected from retaliation during probation exactly as afterwards. Where a probationary dismissal follows closely on a protected activity, the timing itself invites scrutiny, and a thin assessment record will not withstand it.

What "suitability" actually means

Where a probationary clause is valid, the employer is generally expected to have assessed the employee’s suitability in good faith: to have given them a fair opportunity to demonstrate they could do the job, measured against expectations they were actually told about. Suitability is broader than competence — it can take in reliability, judgement, and fit with the way the team works — but it is not a licence to dismiss for any reason or none.

A dismissal with no evidence that any assessment occurred is a weak position even inside a well-drafted probationary period. The question a decision-maker asks is not whether the employer was entitled to be dissatisfied, but whether the employer actually turned its mind to suitability and gave the employee a genuine chance to meet a known standard.

Running a probationary period that holds up

• Write down the expectations for the role and share them at the start, not at the end.
• Hold at least one documented check-in before the period closes, while there is still time to correct course.
• Say plainly when performance is falling short, and record that you said it — a reassuring conversation followed by a dismissal is difficult to defend.
• Record the specific, job-related reasons if you decide not to continue the relationship.
• Diarize the end of the period — letting it lapse unnoticed removes whatever benefit the clause offered.
• Pay whatever statutory entitlement has accrued even where you are satisfied the probationary standard was met; the clause governs the assessment, not the statutory floor.

Extending, and other things that quietly go wrong

Extending a probationary period is not automatic. Unless the contract expressly permits an extension, doing so is a change to an agreed term and raises the same consideration problem as any mid-employment amendment. An extension imposed unilaterally may simply be ineffective, leaving the employer past the original end of the period with none of its benefit.

Two more patterns cause avoidable trouble. Rehiring a former employee into a fresh probationary period ignores that prior service may count toward statutory entitlements. And applying a probationary clause to an internal promotion is usually ineffective, because the employee is already employed and the new terms need their own consideration.

Four assumptions worth discarding

Most probation disputes trace back to a small set of beliefs that sound reasonable and are not correct:

• "Probationary employees can be let go without notice." Statutory notice depends on length of service, not on what the contract calls the period. Once the service threshold is passed, notice is owed whatever the clause says.
• "We don't need a reason during probation." You need a reason connected to suitability, assessed in good faith, and you need to be able to show you formed it. Not needing just cause is not the same as not needing anything.
• "The handbook says employees are probationary, so they are." A policy document circulated after hiring generally does not create a contractual term the employee agreed to before starting.
• "Probation protects us from a human-rights complaint." It does not, at any point. Protected grounds and reprisal protections operate from the first day of employment onward.

If it is not working out

Deciding not to continue is a legitimate outcome of a probationary period, and handling it well costs very little. Confirm the period has not already lapsed, confirm what statutory entitlement has accrued and pay it without argument, and write the reason down in job-related terms before the meeting rather than reconstructing it afterwards.

Resist the temptation to soften the message into something that does not match the file. Telling a departing employee the role was eliminated, when the reason was suitability, creates an inconsistency that surfaces the moment the position is reposted. Brief, accurate, and consistent survives scrutiny; kind-but-inaccurate does not.

Have an employment lawyer review your standard offer and probationary language once, properly. It is the cheapest point in the entire employment relationship at which to fix this, and the clause you use is likely to be reused across every hire you make.
