Working Without an Employment Contract in Ontario: What the Law Provides and Why It Can Work in Your Favour
achkarlaw-admin2026-05-22T11:44:25-04:00Many employees in Ontario start working without signing a written employment contract. This is more common than people expect, particularly when a job begins quickly or an employer delays providing paperwork. Working without a written contract is legal in Ontario, but it creates real uncertainty about termination rights, severance, and employment terms that can have significant financial consequences if things go wrong.
Ontario's Employment Standards Act, 2000 applies to all employees regardless of whether they have a written contract. Common law reasonable notice also applies on termination where no valid written termination clause exists. In many cases, the absence of a written contract actually strengthens your position on termination.
Were you terminated without a written contract and offered only the ESA minimum?
Without a valid written termination clause, your employer may owe you common law reasonable notice, which is frequently significantly higher than the statutory minimum. Get advice before signing any release.

Even without a written agreement, Ontario law provides meaningful protections. An employment relationship can exist through a written contract, a verbal agreement, or an implied agreement based on conduct and the circumstances of how employment began. Courts recognize all three as legally valid.
The risks of working without a written contract
Unclear employment terms
Without a written agreement, proving the specific terms of your employment, including salary, bonus entitlements, job responsibilities, and benefits, depends on emails, text messages, job postings, and witness evidence. This creates uncertainty if a dispute arises.
Disputed termination rights
Termination is where the absence of a written contract matters most. Without a valid termination clause your entitlement defaults to common law reasonable notice. This is frequently much higher than the ESA minimum, but your employer may dispute what was agreed and try to limit what they pay.
Difficulty establishing what was promised
Verbal promises about compensation, bonuses, promotions, or other terms can be difficult to prove without written documentation. Courts may have to determine employment terms based on circumstantial evidence, which is uncertain for both sides.
Vulnerability to unilateral changes
Without a written agreement, it can be harder to establish exactly what your original terms were, making it more difficult to identify and challenge significant unilateral changes to your role or compensation as constructive dismissal.
When your employer tries to introduce a contract after you have already started
Employers sometimes attempt to introduce a written employment contract after an employee has already been working for some time. This raises important legal issues. A contract that significantly changes your existing rights requires fresh consideration something of value provided in exchange, such as a raise, a bonus, or a promotion. Simply being told to sign or face termination is generally not sufficient consideration.
If your employer is asking you to sign a new contract that limits your termination rights or changes your compensation after you have already started working, get legal advice before signing. A contract signed under pressure or without meaningful consideration may be unenforceable. For a full explanation of how employment contract enforceability works see our guide to employment contracts in Ontario.
Were you terminated without a written contract or is your employer asking you to sign one now?
Without a valid written termination clause, you may be entitled to significantly more than the ESA minimum on dismissal. And a contract introduced after you start working may require consideration to be enforceable. Get advice before acting.

Frequently asked questions about working without an employment contract in Ontario
Can you legally work in Ontario without a written employment contract?
Yes. Employment contracts do not need to be in writing to be legally valid in Ontario. An employment relationship can exist through a verbal agreement or through the implied conduct of both parties. All ESA minimum protections apply regardless of whether a written contract exists.
What are my rights on termination if I never signed a contract?
Where no written employment contract exists, or where the contract does not contain a valid termination clause, your entitlement on a without-cause termination defaults to common law reasonable notice. This is calculated based on your age, length of service, the nature of your role, and the availability of comparable work. It has no fixed cap and is frequently significantly higher than the ESA minimum of one week per year up to eight weeks.
Can my employer limit my severance by introducing a contract after I start?
Not without providing you with something of value in exchange for signing, known legally as fresh consideration. A contract introduced after employment has already begun that significantly limits your termination rights requires a meaningful benefit such as a raise, bonus, or promotion to be enforceable. Simply being told to sign does not constitute consideration. If you signed a contract after starting work and were not given anything in return, the termination clause may be unenforceable.
How does a court determine my employment terms without a written contract?
Courts look at the totality of the employment relationship including emails, text messages, job postings, verbal agreements established through witness evidence, workplace policies, and the conduct of both parties over the course of employment. Where terms are ambiguous or disputed, courts generally interpret them in favour of the employee on the basis that the employer, as the author of the employment relationship, had the opportunity to put clear terms in writing and chose not to.
My employer promised me things verbally that they are now denying. What can I do?
Verbal promises about compensation, bonuses, benefits, or other employment terms can be enforceable where they can be proven. Gather any supporting evidence including emails, text messages, messages from colleagues who witnessed the conversation, or documents that corroborate what was promised. Get legal advice about whether the promise is enforceable and how to pursue it.
Should I ask my employer for a written employment contract?
Yes, but carefully. A written contract creates clarity, but it may also contain termination clauses that limit your common law entitlement. If your employer provides a contract, have it reviewed by a lawyer before signing. An unfavourable termination clause could significantly reduce your severance entitlement.
