QUICK ANSWER
Ontario has no single law that defines “full-time” with a fixed number of hours. In practice, full-time employment in Ontario is generally understood to mean working 40 hours per week, though many employers use anywhere from 35 to 44 hours as their standard. What the law does define clearly is the maximum hours an employer can require — and what happens when those hours are exceeded.
Why there is no single legal definition
Many people search for the official legal definition of full-time hours in Ontario expecting to find a specific number — like 40 hours — written into the law. The truth is that Ontario’s Employment Standards Act, 2000 (ESA) does not define “full-time” employment with a set number of hours. The ESA leaves that to the agreement between the employer and the employee, which is typically set out in an employment contract, a collective agreement, or the employer’s standard workplace policy.
What the ESA does define very clearly are the rules around maximum hours of work, overtime, and the protections that apply to all employees — whether they work full-time, part-time, or something in between.
What is generally considered full-time in Ontario?
While the law does not set a fixed number, here is what is commonly understood and used across Ontario workplaces:
35–40
Hours per week most commonly used by Ontario employers as the full-time standard
44
Maximum hours per week an employer can require before overtime pay kicks in under the ESA
8
Hours per day considered a standard workday in most Ontario employment contracts
What the ESA actually says about hours of work
Even though the ESA does not define full-time, it sets firm rules that protect all employees regardless of how many hours they work. Here are the key ones every Ontario employee and employer should know:
Maximum hours of work
An employer cannot require or even allow an employee to work more than 8 hours in a day or 48 hours in a week — unless the employee has agreed in writing and the employer has received approval from the Director of Employment Standards. This is a hard ceiling, not a guideline.
Overtime threshold
Once an employee works more than 44 hours in a week, every additional hour must be paid at a rate of at least 1.5 times their regular pay — what most people call “time and a half.” This applies regardless of whether the employee is called full-time or part-time.
Rest periods
Every employee is entitled to at least 11 consecutive hours off each day, at least 8 hours off between shifts, and at least 24 consecutive hours off each week — or 48 hours off every two weeks.
Meal breaks
Employees must receive a 30-minute eating period after every five consecutive hours of work. This break does not have to be paid — unless the employee is required to stay at their workstation during the break.
Full-time vs. part-time — what is the practical difference?
While the law does not draw a hard line between full-time and part-time, the distinction matters in practice — especially when it comes to benefits, job security, and how your employment is structured.

Important: Part-time employees have the same basic legal rights as full-time employees under the ESA. They are entitled to minimum wage, overtime pay after 44 hours, vacation pay, and termination notice. Being called “part-time” does not reduce your legal protections.
What if your employer calls you full-time but gives you unpredictable hours?
This is a growing issue in Ontario — particularly in retail, hospitality, and healthcare. Some employers label workers as full-time in their contract but schedule them inconsistently, leaving them with some weeks at 40 hours and others at 20. If this is happening to you, it matters legally — especially when calculating termination pay, overtime, and benefits entitlement.
Ontario’s ESA does provide some protections here. Under the Fair Workplaces, Better Jobs Act — also known as Bill 148 — employees are entitled to a minimum of 3 hours of pay whenever they are scheduled to work and show up, even if they are sent home early. If your scheduled hours are being reduced significantly without your agreement, that may also amount to a constructive dismissal, depending on the circumstances.
The simple summary
● Ontario law does not define “full-time” with a fixed number of hours — your employment contract or workplace policy sets that standard
● Most Ontario employers treat 35 to 40 hours per week as full-time, with 40 hours being the most common standard
● The ESA caps required hours at 8 per day and 48 per week, with overtime pay after 44 hours
● Both full-time and part-time employees are protected by the ESA — the label on your contract does not determine your rights, your actual situation does
● If your hours are being cut significantly without your agreement, that may be a legal issue worth discussing with an employment lawyer
