Ontario Overtime Calculator (2026)
Ontario's Employment Standards Act 2000 (ESA) sets the overtime threshold at 44 hours per week — four hours higher than the US FLSA standard of 40 hours. Any non-exempt employee who works more than 44 hours in a workweek must receive at least 1.5× their regular hourly rate for all overtime hours. Ontario also permits overtime averaging agreements and time-off-in-lieu (TOIL) arrangements, giving both employers and employees flexibility in how overtime is compensated.

Crucial Fact: Ontario 44-Hour Threshold
Under Ontario Employment Standards Act 2000, Section 22, overtime pay only begins after an employee has worked 44 hours in a workweek. Working 42 hours does not trigger overtime pay unless specified in a collective agreement or employment contract. Overtime is paid at 1.5× regular wage.

How This Calculation Works & Applicable Rules
Calculation Methodology
- 01OT Threshold: 44 hours/week under ESA 2000, s. 22 — all hours above 44 must be paid at 1.5× the regular rate.
- 02Regular Rate: The hourly wage upon which overtime is calculated. For piece-rate, commission, or salaried employees, the regular rate must be computed from total earnings divided by hours worked.
- 03Overtime Averaging: Under ESA s. 22(2), employers and employees can agree in writing to average hours over a period of up to 4 weeks to determine overtime entitlement.
- 04Time Off in Lieu (TOIL): ESA s. 22.1 allows employers to provide time off at 1.5 hours for each OT hour worked instead of overtime pay, if the employee agrees in writing.
- 05CPP & EI: Canadian Pension Plan (CPP) and Employment Insurance (EI) premiums are deducted from all earnings including overtime.
Statutory Rules & Provisions
- •Ontario's 44-hour threshold is unique in North America — the US federal FLSA sets 40 hours, and California is even more restrictive with daily overtime after 8 hours.
- •O. Reg. 285/01 provides industry-specific overtime exemptions: managers and supervisors who perform management work more than 50% of their time are exempt from Part VIII (overtime) of the ESA.
- •Construction workers have industry-specific regulations (O. Reg. 213/91) that modify overtime entitlements.
- •Overtime averaging agreements must be in writing, must not exceed 4 consecutive weeks as the averaging period, and must be approved by the Director of Employment Standards if the period exceeds 2 weeks.
- •Minimum wage (General): Ontario General Minimum Wage is $17.20/hr effective October 1, 2025. Overtime premium is always calculated on actual wages — not the minimum wage.

Frequently Asked Questions
Why is Ontario's overtime threshold 44 hours instead of 40?
Ontario's 44-hour weekly overtime threshold was set when the Employment Standards Act was first enacted and reflects a policy choice that was not aligned with the US FLSA 40-hour standard. The threshold has been 44 hours for many decades. Labour advocates have long argued for alignment with the US 40-hour standard, and some Ontario NDP platforms have proposed reducing it to 40 hours, but as of 2025/2026 it remains at 44. This means Ontario employees can work up to 44 hours in a regular workweek without any overtime entitlement — four more hours than in most US jurisdictions.
What is an overtime averaging agreement in Ontario?
An overtime averaging agreement (OAA) is a written agreement between an employer and employee that allows hours to be averaged over a period of up to 4 weeks for the purpose of determining overtime entitlement. Instead of calculating overtime each week independently, the employer can spread hours across the averaging period. For example, a worker might work 50 hours one week and 38 hours the next — in a 2-week averaging period, the average is 44 hours/week, so no overtime is owed. OAAs must be in writing, signed by both parties, and the employer must retain a copy for at least 3 years after the agreement expires.
Can Ontario employees take time off in lieu of overtime pay?
Yes, under ESA 2000, s. 22.1, employees and employers can agree in writing that the employee will take paid time off (TOIL) instead of receiving overtime pay. The TOIL must be calculated at 1.5 hours for each hour of overtime worked. The time off must be taken within 3 months of the workweek in which the overtime was earned (or within 12 months if a written agreement is in place). If the time off is not taken within the required period, the employer must pay the outstanding overtime pay.
