Overtime pay is one of the most frequently violated areas of employment standards law on both sides of the Canada-US border. Employees leave money on the table because they do not know when overtime kicks in. Employers create liability because they misclassify workers, miscalculate the regular rate, or average hours across the wrong time period.
This guide covers the overtime rules in every major Canadian jurisdiction and across US federal and state law — including the important exception that is California. Use our Canada overtime pay calculator or our US overtime pay calculator to run the numbers for your specific situation.
Canadian Overtime Rules: Federal vs. Provincial
Canada's employment standards are primarily provincial — each province sets its own overtime threshold. The exception is federally regulated employees (banks, airlines, telecommunications, interprovincial transport, broadcasting) who are governed by the Canada Labour Code.
Overtime Thresholds by Canadian Jurisdiction
The key distinctions to note: British Columbia is the only province with a meaningful daily overtime trigger alongside its weekly threshold. Ontario's 44-hour threshold is higher than most other provinces, meaning Ontario employees work four extra hours per week before overtime kicks in compared to Quebec, Manitoba, or Saskatchewan workers. Nova Scotia and New Brunswick have the highest threshold in the country at 48 hours.
Ontario Overtime: The 44-Hour Rule in Detail
Ontario's Employment Standards Act requires employers to pay non-exempt employees at 1.5 times their regular rate for each hour worked in excess of 44 hours in a work week. A "work week" is a period of seven consecutive days — and the employer can designate any seven-day period as the work week, provided it is applied consistently.
What Counts Toward the 44 Hours?
Hours of work in Ontario include all time the employee is required to be at the workplace or at a location designated by the employer. This includes: mandatory meetings, required training sessions, waiting time if the employee is required to remain at the workplace, and in many cases travel time when travel is part of the job. It does not include genuine rest periods during which the employee has no work duties and is free to leave.
Overtime Averaging Agreements
Ontario allows employers and employees to enter into overtime averaging agreements that average hours over up to four weeks. Under such an agreement, overtime is only triggered if the average weekly hours exceed 44 over the averaging period. These agreements must be in writing, approved by the employee (or union), and meet specific legislative requirements to be enforceable. Improperly implemented averaging schemes are a common source of overtime liability.
Calculating the Overtime Premium
If a non-exempt employee earns $22/hour and works 48 hours in a week, the calculation is: 44 hours × $22 = $968 straight-time pay, plus 4 overtime hours × ($22 × 1.5) = 4 × $33 = $132 overtime premium. Total weekly pay: $1,100. Use our Ontario overtime calculator to check your numbers instantly.
British Columbia: Daily AND Weekly Triggers
BC's overtime regime is the most protective in Canada because it operates on both a daily and a weekly basis. The daily trigger catches employees who regularly work long days even if their weekly total stays under a threshold.
- Hours 1–8 per day: regular rate
- Hours 8–12 per day: 1.5 times the regular rate
- Hours over 12 per day: 2 times the regular rate (double time)
- Hours 1–40 per week (total): regular rate (subject to daily triggers above)
- Hours over 40 per week: 1.5 times the regular rate
The daily and weekly calculations are not additive — employers pay whichever results in the higher total. If an employee works 10 hours on Monday (triggering 2 hours of daily overtime) but only 35 hours total that week, the daily overtime applies even though the weekly threshold was not reached.
BC Averaging Agreements — Use Caution BC permits overtime averaging agreements similar to Ontario's. However, BC's Employment Standards Branch actively scrutinizes these arrangements, and agreements that reduce employee protections below the Act's minimums are void. Averaging must be genuinely agreed to by the employee — not presented as a condition of continued employment.
US Federal Overtime: The FLSA 40-Hour Rule
In the United States, the primary federal overtime law is the Fair Labor Standards Act (FLSA). The FLSA requires that covered, non-exempt employees receive at least one-and-a-half times their regular rate of pay for every hour worked beyond 40 in a workweek. Unlike many Canadian provinces, the FLSA has no daily overtime trigger — it is purely weekly.
Key FLSA Definitions
Workweek: Any fixed, recurring period of 168 hours (seven consecutive 24-hour periods). The employer can set the workweek to begin on any day and hour. Overtime is calculated within each workweek independently — it cannot be averaged across two or more weeks.
Regular rate of pay: Not just the hourly wage. The regular rate must include all remuneration for employment (except certain statutory exclusions) divided by the total hours worked. This means non-discretionary bonuses, shift differentials, and commissions earned that week must be factored into the regular rate before calculating overtime.
Compensable time: All time the employee is "suffered or permitted" to work. This includes off-the-clock work the employer knew or should have known about, time spent donning and doffing required safety gear, mandatory pre-shift briefings, and certain travel time.
Step-by-Step FLSA Overtime Calculation
Example: Warehouse Worker, 47 Hours in a Week
Note that the productivity bonus increases the regular rate, which in turn increases the overtime premium. Employers who pay bonuses and exclude them from the regular rate calculation are systematically underpaying overtime. Use our US overtime pay calculator to ensure your calculations are compliant.
California: The Daily Overtime Exception
California has the most protective overtime rules of any US state. California Labor Code section 510 creates a three-tier overtime system:
- Hours 8–12 per day: 1.5 times the regular rate
- Hours over 12 per day: 2 times the regular rate (double time)
- First 8 hours on the 7th consecutive day of a workweek: 1.5 times the regular rate
- All hours after 8 on the 7th consecutive day: 2 times the regular rate
- Hours over 40 per workweek: 1.5 times the regular rate (in addition to daily triggers)
California employers cannot average hours across a workweek to avoid daily overtime. An employee who works 12 hours on Monday and 4 hours Tuesday through Friday (total 28 hours) is owed four hours of overtime at 1.5× on Monday alone, even though the weekly total is well under 40. This catches many employers who think they are compliant because their weekly totals are low.
Other states with daily overtime provisions include Nevada (after 8 hours in a day for employees earning less than 1.5 times the state minimum wage) and Alaska (after 8 hours per day or 40 hours per week). Always verify the specific rules of the state where the work is performed.
Overtime Exemptions: Who Is Excluded
Both Canadian and US employment standards exempt certain categories of workers from overtime requirements. These exemptions are frequently misunderstood and misapplied — and improperly classifying an employee as exempt is one of the most expensive mistakes an employer can make.
Exemptions in Canada
Provincial overtime exemptions vary but commonly exclude:
- Managers and supervisors — only when their primary duty is management and they have meaningful authority over hiring, discipline, or firing; a "team lead" with no such authority is typically not exempt
- Professionals — lawyers, engineers, architects, and other regulated professionals are commonly excluded from overtime provisions in most provinces
- Agricultural workers — excluded in some provinces, though this is increasingly subject to human rights challenge
- Commission salespersons — in several provinces, outside salespersons working primarily off-site are exempt
- Information technology professionals — Ontario exempts IT professionals earning above a certain salary threshold
FLSA White Collar Exemptions (US)
The most commonly applied FLSA exemptions are the "white collar" exemptions for executive, administrative, and professional employees. To qualify, the employee must meet BOTH a salary basis test (currently a minimum of $684 per week, or $35,568 annually) AND a duties test showing they primarily perform executive, administrative, or professional work as defined by Department of Labor regulations.
Paying a salary does not automatically make an employee exempt. An employee paid $50,000 per year who primarily performs non-exempt work (data entry, routine processing, customer service) is not exempt simply because they are salaried. And an employee who earns $700/week and supervises two or more employees full-time in their primary duty IS likely exempt. The duties test is the critical analysis.
Common Employer Overtime Mistakes
Overtime violations are common not because employers are deliberately dishonest but because the rules are genuinely complex and frequently misunderstood. These are the errors that most often generate back-pay liability:
1. Misclassifying Employees as Exempt
Calling someone a "manager" or "supervisor" does not make them exempt. The duties test matters. An employee who manages no one, makes no hiring or firing decisions, and primarily performs the same tasks as the non-exempt staff below them is almost certainly non-exempt — regardless of title.
2. Calculating Overtime on Base Salary Alone
The regular rate must include non-discretionary bonuses, production incentives, shift differentials, and other forms of remuneration that are regularly paid to the employee. Calculating overtime only on the base rate while ignoring bonuses systematically underpays overtime when those bonuses are present.
3. Averaging Hours Across Pay Periods
In Canada, averaging requires a written agreement that meets specific regulatory requirements. In the US, it is simply not permitted under the FLSA — each workweek stands alone. An employer who says "you worked 50 hours this week but only 30 last week, so it averages out" is violating the law.
4. Not Counting All Compensable Time
Mandatory pre-shift briefings, required training outside regular hours, on-call time where the employee's freedom is significantly restricted, and certain travel time all count as hours worked for overtime purposes. Employees who are required to start their computer and load programs before clocking in — or who respond to work emails at home — may be owed overtime for that time.
5. Using Comp Time Instead of Pay
In the private sector in Canada and the US, comp time (giving time off in lieu of overtime pay) is generally not permitted as a unilateral employer practice. Some provinces allow "time off in lieu" agreements with employee consent, and federal law in the US restricts comp time to public-sector employees. Private-sector employers who bank comp time without a compliant agreement are accruing overtime liability.
