How Many Employees Does One 24/7 Post Need in Canada?
Holding one position every hour of 2026 in Canada takes 8,766 staffed hours. One full-time employee is genuinely available for about 1,806 of them, so the post needs 4.85 employees, which is 5 whole people.
One ring per person, one year each
Each ring is one employee's year, broken wherever they are on holiday, on leave, or off sick. No single ring closes, which is the whole problem: one person cannot hold a post that never stops.
Stack 5 of them and the picture closes. Trace any line out from the center and it crosses at least one solid arc, so every hour of 2026 has somebody on it. That is the relief factor, drawn rather than asserted.
Where the number comes from
- 1
Staffing one position 168 hours a week comes to 8,766 hours across the year.
- 2
Canada has 261 weekdays in the year, the starting point for one employee.
- 3
Take out 8 public holidays that fall on a weekday, 10 days of statutory paid leave, 9.1 days of average sickness absence, and 3 days of training: 30.1 days lost.
- 4
That leaves 230.9 working days per employee, and at a 39.1-hour week that is 7.82 hours a day, so 1,806 available hours a year.
- 5
8,766 coverage hours divided by 1,806 available hours is a relief factor of 4.85, so the post needs 5 people.
| Weekdays in the year | 261 |
| Public holidays on a weekday | −8 |
| Statutory paid annual leave | −10 |
| Average sickness absence | −9.1 |
| Training and onboarding (assumed) | −3 |
| Working days available | 230.9 |
| At 7.82 hours a day | 1,806 hours |
Paid public holidays are a statutory entitlement in Canada, so they sit on top of annual leave and are deducted separately here.
The training allowance of 3 days is a planning assumption rather than a sourced statistic, and it is deliberately low. Every other figure on this page carries a source. If your operation runs heavy certification cycles, raise it and the relief factor rises with it.
What the usual rule of thumb gets wrong here
The common shortcut is to divide coverage hours by contracted hours and add a quarter for absence. In Canada that gives 5.37 against a derived answer of 4.85, so the shortcut is high by 10.6 percent. A flat buffer travels badly because the things it stands in for, statutory leave and the length of the contracted week, are set nationally.
Nobody ever away. Not a real answer.

Other coverage shapes
The same availability figure answers any coverage window. Only the hours the post must be staffed change.
| Coverage | Hours a week | Relief factor | People |
|---|---|---|---|
| Round the clock, every day | 168 | 4.85 | 5 |
| Round the clock, weekdays only | 120 | 3.47 | 4 |
| Two shifts, every day | 112 | 3.24 | 4 |
| Extended day, weekdays only | 60 | 1.73 | 2 |
If your contract is more generous
10 days is the statutory floor in Canada, and most employers sit above it. Every extra week of leave is another week the post has to be covered by somebody else.
| Annual leave | Relief factor | People per post |
|---|---|---|
| 10 daysstatutory floor | 4.85 | 5 |
| 20 days | 5.07 | 6 |
| 25 days | 5.19 | 6 |
| 28 days | 5.27 | 6 |
| 30 days | 5.32 | 6 |
| 33 days | 5.39 | 6 |
The inputs, and what they do not say
How the leave figure is defined
Stated in WEEKS in law, not days. Canada Labour Code s.184 gives at least 2 weeks after 1 completed year of employment, converted here to 10 working days on a 5-day week. The figure EXCLUDES public holidays: general holidays are a separate paid entitlement, and CLC s.187 lets vacation be extended by one day for each general holiday that falls inside it, which confirms the two are not overlapping.
Why the contracted week is not the legal maximum
This page divides by a 39.1-hour week, the typical full-time contract in Canada, not by the 40-hour statutory figure. That larger number is a legal ceiling on how much someone may be asked to work, not a description of what a full-time employee is contracted for, and using it as capacity would understate the headcount a post needs.
The holiday count is a floor
Most public holidays in Canada are set regionally rather than nationally, so this page counts only the 8 days observed across the whole country. A specific region will observe more, which pushes the relief factor up. The public holiday calendar for Canada lists the regional days.
What these figures cannot be used for
Not a ranking. The sickness figure here comes from a national statistical source, while other countries in this library use the OECD labour force survey. Those systems define absence differently, and self-reported survey figures undercount short spells that administrative records capture. Each number is the best available answer for planning inside its own country, and the gap between any two of them is partly a gap between statistical methods rather than between workforces.
A relief factor also says nothing about whether a roster is legal or humane. It sets how many people the post needs across a year; it does not check rest periods between shifts, consecutive nights, or weekend distribution. Those constraints decide whether the pattern you build on top of this headcount is one anybody can actually work.
Research notes on Canada
Jurisdiction is the main trap. Only about 904,000 employees, roughly 6 percent of the workforce, are covered by the Canada Labour Code. Everyone else falls under one of 13 provincial or territorial employment standards acts, so no single national number is exactly right for any given employer.
Weekly hours: 40 is the federal STANDARD week (CLC s.169, 8 hours a day and 40 a week); the federal hard ceiling is 48 (s.171). Do not treat 40 as a universal overtime trigger. Ontario, the largest labour market, defines no 40-hour standard at all: the daily limit is 8 hours or the employee's regular workday, the weekly cap is 48, and overtime starts only after 44 hours. Alberta also uses 44. A model that pays overtime above 40 everywhere will overstate Ontario cost.
Contracted week: 39.1 is Statistics Canada Labour Force Survey average USUAL weekly hours for full-time employees (2025 average of the 12 monthly values, range 39.0 to 39.2). It is a statistical average, not a bargained standard. Canada has no sectoral bargaining, so the gap to statutory is small: union-covered full-timers averaged about 38.5 to 38.6 hours in 2025 versus 39.3 for non-union. Corroborating figure from table 14-10-0043-01 is 39.7 for full-time employment, higher because it includes the self-employed.
Annual leave: 10 working days is the floor, and only after a full year of service. Vacation TIME generally accrues only after 12 completed months, though vacation pay accrues from day one. Saskatchewan's floor is 3 weeks (15 working days) from year one, the highest in the country. Federally and in most provinces the entitlement steps up to 3 weeks after 5 years and 4 weeks after 10, so 10 days badly understates what a tenured team will actually book.
Public holidays are on top and are the single most common error in Canadian data: 10 federal general holidays under CLC s.166, 9 public holidays in Ontario. A planner who models 10 leave days and no holidays is short by another 9 or 10 absent days per person.
Sickness: 9.1 days is "days lost per worker in a year, illness or disability" for full-time employees, Canada, 2025. Statistics Canada derives it as the inactivity rate multiplied by an assumed 250-working-day year (52 x 5 minus 10 statutory holidays), so it already sits on a working-day base that matches a 5-day roster. No percentage conversion was needed. Total days lost including personal or family responsibility is 11.0; use that instead if your coverage model treats carer absence as unplanned. Sector spread is large: public sector 13.3 illness days versus private sector 7.7 in 2025, so a single national number will badly misprice a public-sector or healthcare roster. The series covers full-time employees only; part-timers are outside the base, and maternity or parental leave is not counted here.

Common questions
- How many people does one 24/7 position need in Canada?
- 5 people. One position staffed every hour of the year is 8,766 hours, and one full-time employee in Canada is actually available for about 1,806 of them once 30.1 days of holidays, leave, sickness and training come out. That is a relief factor of 4.85, which rounds up to 5 whole people.
- What is a relief factor?
- The number of employees needed to keep one position filled continuously, once the days nobody works are taken out. It is coverage hours divided by the hours one employee is genuinely available. In Canada that is 8,766 divided by 1,806, or 4.85. A factor below the headcount you actually employ means the post runs on overtime.
- Why is a flat 25 percent absence buffer not enough for Canada?
- Because it overshoots here. A raw hours calculation gives 4.29 employees, and adding a flat quarter takes that to 5.37, against a derived answer of 4.85. That is 10.6 percent too high, because the rule of thumb assumes more leave and sickness than Canada actually loses.
- Does the statutory leave minimum reflect what employers actually give in Canada?
- It is a floor, not a norm. This page computes on the statutory minimum of 10 working days because that is the figure the law fixes and a source can be attached to. Most employers sit above it, and the sensitivity table on this page shows what the relief factor becomes at more generous entitlements, so a planner can find their own contract rather than taking the floor as the answer.
