How Is Overtime Pay Calculated in Ontario

Reviewed by Calculator Editorial Team

Overtime pay is a crucial aspect of employment law in Ontario. Understanding how it's calculated can help employees and employers comply with regulations and make informed decisions about work hours and compensation.

How Overtime Is Calculated

In Ontario, overtime pay is calculated based on the number of hours worked beyond the standard 40-hour workweek. The Ontario Employment Standards Act (ESA) outlines the rules for calculating overtime pay.

Overtime Pay = (Hourly Rate × 1.5) × Number of Overtime Hours

The calculation involves multiplying the employee's hourly rate by 1.5 for each hour worked beyond 40 in a workweek. This applies to both regular and premium overtime, with some exceptions.

Step-by-Step Calculation

  1. Determine the employee's hourly rate
  2. Calculate the number of overtime hours (hours worked - 40)
  3. Multiply the hourly rate by 1.5
  4. Multiply the result by the number of overtime hours
  5. Add the overtime pay to the regular pay

Note: The Ontario ESA requires employers to pay overtime for hours worked beyond 40 in a workweek, regardless of whether the employee is exempt or non-exempt.

Regular vs. Premium Overtime

Overtime in Ontario can be classified as either regular or premium, depending on the circumstances.

Regular Overtime

Regular overtime applies to hours worked beyond 40 in a workweek on a regular day (Monday to Friday). The calculation is straightforward:

Regular Overtime Pay = (Hourly Rate × 1.5) × Regular Overtime Hours

Premium Overtime

Premium overtime applies to hours worked on weekends (Saturday and Sunday) or holidays. The calculation is similar but includes an additional premium rate:

Premium Overtime Pay = (Hourly Rate × 2) × Premium Overtime Hours

This means employees earn double their regular hourly rate for weekend and holiday work beyond 40 hours in a week.

Practical Examples

Let's look at some practical examples to illustrate how overtime pay is calculated in Ontario.

Example 1: Regular Overtime

An employee works 45 hours in a week at an hourly rate of $20. How much overtime pay is due?

Overtime Hours = 45 - 40 = 5 hours Overtime Pay = (20 × 1.5) × 5 = $150

Example 2: Premium Overtime

An employee works 50 hours on a Saturday at an hourly rate of $20. How much premium overtime pay is due?

Overtime Hours = 50 - 40 = 10 hours Premium Overtime Pay = (20 × 2) × 10 = $400

Example 3: Combined Regular and Premium Overtime

An employee works 45 hours on a Monday and 10 hours on a Saturday at an hourly rate of $20. How much total overtime pay is due?

Regular Overtime Hours = 5 Premium Overtime Hours = 10 Regular Overtime Pay = (20 × 1.5) × 5 = $150 Premium Overtime Pay = (20 × 2) × 10 = $400 Total Overtime Pay = $150 + $400 = $550
