Before adding more resources, hospitals need a clearer picture of the capacity they already have.
Canadian hospitals have been adding staff for years. Yet maintaining reliable staffing coverage remains a challenge for many healthcare organizations.
According to the Canadian Institute for Health Information (CIHI), hospitals added approximately 87,000 full-time equivalents (FTEs) between 2014 and 2023, a 24% increase. After accounting for population growth, hospital staffing per 100,000 people increased by 9%.
That is meaningful growth. But it raises a question worth exploring: how much of that workforce translates into the right coverage, in the right place, at the right time?
The answer isn't simply a matter of headcount. It depends on how workforce capacity is planned, scheduled and deployed.

Headcount and capacity are not the same thing
Knowing how many people an organization employs is important. Knowing how many people are available to meet its staffing requirements is a different calculation.
A hospital may have a substantial workforce on its books and still struggle to cover particular shifts, units or roles. Some employees work part-time. Others have specific qualifications or unit restrictions. Leave, absences, contractual rules and the distribution of demand all affect the coverage that can be provided.
This is particularly important in a 24/7 environment. Having enough staff in total does not necessarily mean having enough qualified staff for a Tuesday night shift in a particular unit.
Nor does this mean every staffing gap can be solved through better scheduling. Hospitals face genuine recruitment and retention challenges, and some roles are difficult to fill regardless of how efficiently a roster is managed.
But headcount alone cannot explain where the gaps are occurring, why they keep recurring or whether available capacity is being used effectively.
For hospital leaders, the question is increasingly about understanding the relationship between the workforce they have and the coverage they need.
The Canadian workforce picture is not uniform
National figures can tell us a great deal about the direction of the healthcare workforce. They can also hide important differences between regions.
Statistics Canada's analysis of 2024 health-related vacancies found that the vacancy rate for registered nurses was 13.7% in remote regions, compared with 6.7% in accessible regions. For licensed practical nurses, the corresponding rates were 22.6% and 12.1%.
More than six in ten nursing vacancies in remote regions had been open for at least 90 days.
These figures underline an important distinction: some hospitals and communities face a genuine shortage of qualified people, and operational improvements cannot substitute for the recruitment and retention strategies they need.
At the same time, national or provincial vacancy figures cannot tell an individual hospital whether its own staffing gaps are concentrated in particular shifts, units or scheduling patterns.
That requires a closer look at local workforce data.
Four dimensions of workforce capacity
To understand what capacity an organization actually has, it helps to look beyond the total number of employees.
1. Scheduled capacity
How do planned rotations and scheduled hours compare with the coverage required? If the same shifts are repeatedly difficult to cover, leaders may need to examine whether the current rotation reflects actual operational demand.
2. Available capacity
Which employees are available to take on additional work, and when? Availability changes with leave, existing commitments, rest requirements and individual circumstances. A useful picture needs to reflect those constraints rather than assume every employee can cover every gap.
3. Deployable capacity
Of the people who may be available, who is qualified and eligible to work a specific shift or unit? Skills, credentials, collective agreements and local rules all matter. Capacity is useful only when it can be deployed safely and appropriately.
4. Unmet capacity requirements
Where does the organization continue to have gaps despite its existing workforce? Are they concentrated in particular roles, locations, days or times? Are they linked to long-term vacancies, short-notice absences or recurring patterns in the master schedule?
Looking at these dimensions together gives leaders a more practical picture than headcount alone. It also helps distinguish between problems that require additional staff and those where planning, visibility or deployment processes may be contributing to the gap.
What should hospital leaders be asking?
A useful starting point is to examine the relationship between required coverage, scheduled hours and the process of filling vacancies.
Five questions can help:
- Where are the largest differences between required coverage and scheduled staffing?
- Which units, roles and shifts repeatedly experience gaps?
- How quickly are open shifts filled, and how many steps or contacts does that take?
- Are qualified internal employees being reached through a timely and fair process before external coverage is pursued?
- Can leaders see staffing gaps alongside overtime, agency use, employee availability and shift-fill rates?
These questions are not about finding fault with schedulers or asking frontline staff to take on more hours. They are about making the operational picture clearer.
When these measures sit in separate systems or are reviewed independently, it can be difficult to see how one issue connects to another. A recurring vacancy, for example, may look like an isolated event until it is viewed alongside several months of scheduling and staffing data.
From counting people to understanding capacity
A practical workforce capacity review does not need to begin with a large transformation programme.
Hospitals can start by mapping required coverage against scheduled hours, identifying recurring gaps and reviewing how quickly open shifts are filled. They can then compare those patterns with employee availability, overtime and agency use.
The purpose is not to assume every gap can be eliminated. It is to establish where capacity genuinely falls short, where existing resources may be better aligned with demand, and where recruitment or additional resources remain necessary.
Workforce management and scheduling systems can support this work by bringing information about rotations, availability, eligibility and shift coverage into clearer view. They can help teams manage the process more consistently, but they cannot create qualified staff where none are available.
That distinction matters. Better visibility is not a substitute for investment in people. It helps leaders make better-informed decisions about where that investment is needed and how the existing workforce can best support care delivery.
The next workforce question
Recruitment will remain essential to healthcare. So will retention, safe staffing levels and sustainable working conditions.
But hiring numbers alone cannot tell a hospital how reliably it can meet its staffing requirements. Leaders also need to understand how their workforce translates into actual coverage, where capacity is constrained and which operational changes could make a difference.
The question is no longer just how many people a hospital needs to hire.
It is how much of the capacity it has can be translated into the coverage patients need — and where the real gaps remain.
