About Contract of Employment
In Ontario, a "contract of employment" is the fundamental legal relationship that exists between every employer and employee. Unlike standard commercial agreements, this specific type of legally binding relationship is heavily governed by a mixture of the common law and statutory minimums, primarily the Employment Standards Act, 2000 (ESA).
A common misconception is that a contract of employment must be a formal, multi-page document signed by both parties. In reality, under Ontario law, this contract is formed the moment an offer of work in exchange for compensation is accepted. It can be entirely verbal, established through an exchange of emails, or formed by the conduct of the parties.
Every contract of employment contains both "express terms" (what was explicitly discussed or written down, such as your hourly wage or job title) and "implied terms." Implied terms are unwritten rules that the courts automatically read into the employment relationship. The most protective implied term under the common law is the employee's right to receive "reasonable notice" of termination. Unless a legally valid, written termination clause specifically limits this right (while still meeting ESA minimums), the implied contractual right to a generous common law severance package takes precedence.
Disputes frequently arise over the nature of these contracts, particularly when employers summarily dismiss employees (firing without notice based on alleged cause) or when verbal promises made during recruitment contradict written provisions. In some instances, negligent misrepresentation during the hiring process can significantly impact the legal validity of the contract's terms.
Because the foundation of your workplace rights depends on overlapping written agreements, spoken promises, and automatic common law protections, pinpointing exactly what your contract of employment entitles you to is complex. To understand your precise obligations and entitlements, having the history of your hiring and employment relationship evaluated by a legal professional in Ontario is highly recommended.
Frequently Asked Questions
Does my contract of employment have to be in writing to be legally binding?
No. In Ontario, an oral agreement or an agreement formed through a handshake and starting work is a perfectly valid and legally binding contract of employment. However, relying solely on an oral contract means the specific terms will default to common law principles rather than specific written limits.
What happens if I never signed an employment contract?
If you never signed a formal document, you still have an active, binding contract of employment. In the absence of written terms, Ontario common law automatically governs the relationship, reading in "implied terms" such as the requirement for your employer to provide reasonable notice if they dismiss you.
Can my employer enforce a contract rule that offers less than the ESA?
No. The Employment Standards Act, 2000 sets out absolute minimum requirements for things like minimum wage, vacation, and termination pay. Any term in a contract of employment that attempts to provide less than these statutory minimums is legally void.
Are promises made during a job interview part of my legal contract?
They can be, particularly if you relied on those promises to accept the job. However, if you later sign a written document containing an "entire agreement" clause, it may overwrite earlier verbal promises. Disputes over such issues often involve claims of negligent misrepresentation.
When should I have an employment lawyer look at my contract?
It is generally wise to consult legal counsel before resigning from your current job to accept a new offer, or if you are presented with a new contract to sign mid-employment. A lawyer can tell you exactly which rights you might be unknowingly signing away.
Common Scenarios
- An individual is hired at a restaurant on a verbal agreement and terminated five years later; the employer wrongly assumes no severance is owed because there was no "official" signed document.
- A worker leaves a secure position based on an executive's verbal promise of lucrative stock options, only to be given a written contract on their first day that completely excludes those promised options.
- A long-tenured employee is abruptly fired without notice for a minor mistake, leading to a legal dispute where the employee claims a breach of the implied contractual term of reasonable notice.
- During a company acquisition, a worker is handed a new manual outlining strict new terms of employment, leading to conflict over whether these new terms validly replaced their original, unwritten contract.
What You Should Know
- Retain copies of all early emails, text messages, offer letters, and job descriptions, as these pieces of evidence help prove the terms of your contract of employment if no formal consolidated document exists.
- Remember that continuing to work after an employer verbally promises you a raise or a new work hours arrangement can legally solidify those new terms as part of your ongoing contract.
- Never assume that a lack of signed paperwork means you lack fundamental workplace protections, as the Ontario common law automatically fills in missing terms to protect employees.
- Because the interplay between verbal promises, implied workplace duties, and unwritten expectations is intricate, getting a legal practitioner to clarify the true parameters of your binding relationship is a smart step before making major career moves.
