Employment Contracts in Ontario: Key Terms to Know

An employment contract sets out the terms of the relationship between an employer and an employee in Ontario — what the role involves, how the employee will be paid, and what happens if the relationship ends. While an employment relationship can exist without any written agreement at all, a written contract gives both sides clarity on key terms that would otherwise be left to a mix of statutory minimums and less predictable common-law rules developed through court decisions.

Core terms generally include the employee’s role and reporting structure, compensation (base pay, bonus, benefits), hours of work, and the circumstances under which either side can end the employment relationship. Many contracts also include restrictive covenants — provisions limiting what an employee can do during or after employment, such as confidentiality and non-solicitation obligations.

Importantly, an employment contract in Ontario operates within a framework set by legislation, most notably the Employment Standards Act, which establishes minimum standards the contract can’t validly fall below no matter what the parties agree to in writing.

A written contract also tends to benefit both sides in less obvious ways. For an employer, it creates a documented record of what was agreed at the outset of the relationship, which can matter considerably if a dispute arises years later. For an employee, it provides a concrete reference point for compensation, role expectations, and entitlements, rather than relying on memory or informal conversation about what was promised when they were hired.

The role description in an employment contract typically covers job title, core duties, and reporting lines, sometimes with language allowing the employer some flexibility to adjust duties over time as business needs change. A role description that’s too rigid can create friction as a business evolves, while one that’s too vague can leave an employee uncertain about what’s actually expected of them.

Compensation terms should clearly state base salary or wage, payment frequency, and the structure of any bonus, commission, or benefits that form part of total compensation. Whether bonus or commission amounts are discretionary or guaranteed is a detail worth spelling out explicitly, since vague compensation language is a common source of disputes, particularly when an employee’s employment ends partway through a bonus period.

Hours of work, overtime eligibility, and vacation entitlement round out the core compensation-related terms, and these generally need to meet or exceed the minimums set by the Employment Standards Act regardless of what the contract itself specifies.

Benefits — including health and dental coverage, retirement contributions, and any allowances for things like a vehicle or phone — are often addressed in a separate benefits plan document rather than the employment contract itself, with the contract simply referencing eligibility. Where this is the approach taken, it’s worth understanding that the details governing those benefits typically live in the plan documents rather than the contract, and the two should generally be read together.

Termination provisions are often the single most consequential — and most frequently litigated — part of an Ontario employment contract. The Employment Standards Act sets minimum notice periods (or pay in lieu of notice) based on length of service, along with separate statutory severance pay for eligible employees at larger employers. These are floors, not suggestions: a termination clause that tries to provide less than the ESA minimum is generally void, meaning it’s treated as though it never existed, rather than simply being reduced down to the legal minimum.

When a termination clause is found void, the result is usually that the employee becomes entitled to common-law reasonable notice instead — an amount determined by a range of factors including length of service, age, position, and the availability of similar employment, which is very often substantially larger than the ESA minimums alone.

Our guide to severance and termination clauses in Ontario goes into more depth on how ESA minimums and common-law reasonable notice differ in practice.

Given how significant the gap between these two frameworks can be, both employers and employees generally benefit from understanding, before a contract is ever signed, which standard would actually apply if the relationship were to end. This is rarely obvious from a quick read of a termination clause, since the clause’s language — not just its apparent intent — determines whether it validly limits the employee to ESA minimums.

Restrictive covenants limit what an employee can do during or after their employment. Confidentiality clauses protect an employer’s sensitive business information and are broadly enforceable. Non-solicitation clauses, which restrict an employee from soliciting an employer’s clients or staff after leaving, are also commonly used and generally enforceable provided they’re reasonable in scope.

Non-compete clauses are treated quite differently under Ontario law. The Employment Standards Act generally prohibits non-compete agreements for most employees, with narrow exceptions — including certain executives and situations tied to the sale of a business. Our guide to non-compete agreements in Ontario covers this restriction, and the exceptions to it, in more detail.

Even where a restrictive covenant is legally permitted, courts generally expect it to be reasonable in scope, duration, and geography to protect a legitimate business interest. An overly broad covenant risks being found entirely unenforceable rather than simply narrowed down to a reasonable version by a court.

A probationary period allows an employer to assess a new employee’s suitability for the role over an initial period, often with a shorter notice requirement for ending the employment during that window. Importantly, this reduced notice treatment doesn’t apply automatically just because an employee is newly hired — it generally needs to be set out clearly in the written contract to have its intended legal effect.

Even during a probationary period, an employer still generally needs to meet the minimum notice requirements under the Employment Standards Act for employees who’ve completed at least a short minimum period of employment, and termination still can’t be for a reason prohibited by human rights or other legislation.

A probationary period is also distinct from a general introductory or training period that isn’t tied to any specific contractual notice provision. Without language in the contract expressly establishing a probationary period and describing its effect on notice, simply referring to a new hire informally as being “on probation” generally doesn’t change their legal entitlements on termination.

Most Ontario employment relationships are indefinite-term, meaning they continue until either party ends them, generally with notice. There’s no general concept of “at-will” employment in Canada — the U.S. idea that either side can end employment at any time, for almost any reason, without notice, doesn’t apply here.

A fixed-term contract is different: it’s set to end automatically on a specific date or when a defined project concludes, without either side needing to give notice at that point. Fixed-term contracts carry their own risk for employers in particular — ending one early without a properly drafted early-termination provision can, in some circumstances, require paying out compensation for the entire remainder of the fixed term, which can significantly exceed what would be owed under an indefinite-term arrangement.

Fixed-term contracts also raise their own questions around renewal. Where a fixed-term contract is repeatedly renewed over a long period, the overall pattern of the relationship — rather than the label used in any single renewal — can affect how the relationship is ultimately characterized if a dispute arises. This is one reason a series of back-to-back fixed-term contracts isn’t automatically treated the same as a single long indefinite-term relationship, and vice versa.

Whether you’re an employer drafting a contract or an employee reviewing one, the termination section generally deserves the closest attention, given how often these clauses end up being the focus of a later dispute. Compensation structure and restrictive covenants are worth a careful read as well.
