How overtime works in Alberta
Under Employment Standards Code, s. 21, an employee in Alberta is entitled to overtime pay of 1.5× their regular hourly rate for every hour worked beyond the threshold.
Alberta applies both a daily and a weekly threshold. Overtime is triggered once an employee works more than 8 hours in a single day or more than 44 hours in a week. Overtime hours are calculated as the greaterof daily or weekly excess — not the sum. Use the "day by day" input mode in the calculator above for an accurate result.
Special rules & edge cases
- •Overtime is the GREATER of daily or weekly excess — you do not add them together.
- •Averaging agreements and compressed work weeks must be filed in writing.
Worked example
An employee in Alberta earning $25/hour works 9 hours each day, Monday to Friday (45 total): daily OT is 5 hours, weekly OT is 1 hours. The greater of the two is 5 hours of overtime, paid at $37.50/hour.
