Ontario Overtime Calculator
Under Ontario's Employment Standards Act, most employees earn overtime pay at 1.5× their regular rate for hours worked over 44 in a week — Ontario has no general daily overtime rule. This page presets the 44-hour threshold: a 46-hour week at $20/h pays 44 × $20 + 2 × $30 = $940. Many occupations are exempt or covered by special rules (some professionals, IT professionals and supervisors among them), and hours can be averaged over up to four weeks only with a valid written averaging agreement — this page models the standard single-week rule with no averaging.

Frequently asked questions
After 44 hours in a workweek for most employees under the Employment Standards Act — not after 40 (that is the federal/FLSA figure and several other provinces' rule). Hours beyond 44 are paid at least 1.5× the regular rate.
No general daily rule: an employee can work a 12-hour day without daily overtime as long as the week stays within 44 hours (daily maximum-hours and rest rules still apply). Only the weekly 44-hour threshold triggers the premium in the standard model.
44 hours at $20 plus 2 hours at $30 (1.5×) = $880 + $60 = $940 gross, which is the worked example preset on this page.
The ESA exempts or applies special rules to many roles — including some professionals, information-technology professionals, and managers/supervisors (for work of a managerial character). This calculator models the standard non-exempt rule only.
Yes, but only under a written averaging agreement (employer and employee, or a collective agreement) covering up to four weeks; overtime then applies after an average of 44 hours a week over the period. This page does not model averaging — it prices a single week.
