Overtime rules in Canada are set provincially. Most provinces require 1.5× regular pay after a weekly hour threshold, but the threshold varies: 40h in BC, Quebec, Manitoba, Saskatchewan, Newfoundland; 44h in Ontario, Alberta, New Brunswick; 48h in Nova Scotia and PEI.
Daily overtime
BC and Alberta apply overtime after 8 hours in a day, whichever threshold (daily or weekly) triggers first. BC adds an additional 2× multiplier after 12 hours in a single day.
Exemptions
Managers, IT professionals in some provinces, truck drivers under federal rules, and agricultural workers often have exemptions or different thresholds. Check your specific ESA.
