Ontario Employment Standards Act (ESA)
Ontario has a slightly higher weekly threshold than many other regions, starting overtime calculation at 44 hours rather than 40.
Reviewed by the Time Card Maker editorial team:
No daily overtime limit in the ESA (unless specified in contract/union agreement).
Overtime (1.5x) begins after 44 hours in a workweek.
Not required by the ESA.
Ontario Employment Standards Act (ESA) in plain language
For most Ontario employees covered by the general ESA rule, overtime begins after 44 hours in a workweek and is paid at one and one-half times the regular rate. Ontario does not generally create statutory overtime merely because one day exceeds eight hours.
Key terms for this calculation
- Workweek
- A recurring seven-day period established for calculating hours and overtime.
- Overtime rate
- At least one and one-half times the regular rate for covered overtime hours.
- Averaging agreement
- A written or electronic agreement to average hours across a specified two- to four-week period, subject to ESA conditions.
Ontario Employment Standards Act (ESA): worked example
A covered employee with a $25 regular rate works 48 hours in one workweek without an averaging agreement.
- 44 regular hours × $25 = $1,100
- 4 overtime hours × $37.50 = $150
- Estimated gross wages = $1,100 + $150
$1,250 before deductions.
Special rules, exemptions, multiple rates, averaging, or paid-time-off agreements may alter the result.
