One of the most common questions employers ask when they first engage a staffing agency is whether they should hire temporary or permanent workers. The honest answer is that it depends — and often the right answer is a mix of both. Understanding the practical differences helps you make a more informed decision for each role you need to fill.
What temporary staffing actually means
When you hire through a staffing agency on a temporary basis, the worker is employed by the agency — not by you. The agency handles payroll, source deductions, WSIB premiums, and employer obligations under the Employment Standards Act. You pay a bill rate that covers the worker's wages plus the agency's markup, which accounts for those employer costs and the agency's fee.
This arrangement gives you workforce flexibility without adding headcount to your payroll. You can scale up for a production surge and scale back down when demand normalises, without the administrative burden of hiring and terminating employees directly.
When temporary staffing makes sense
- Variable demand: If your production volume fluctuates seasonally or by contract, temporary staffing lets you match your workforce to your actual workload.
- Short-term projects: For a defined project with a clear end date, temporary workers are a cleaner fit than permanent hires you would need to let go when the project wraps.
- Covering absences: Temporary workers can fill in for employees on leave without disrupting your permanent headcount.
- Evaluating fit before committing: A temp-to-permanent arrangement lets you assess a worker's performance and culture fit before making a permanent offer.
What permanent placement means
In a permanent placement, the staffing agency recruits and screens candidates on your behalf, and you hire the selected candidate directly onto your payroll. You pay the agency a one-time placement fee — typically a percentage of the worker's first-year salary — and the employment relationship is between you and the worker from day one.
Permanent placement is appropriate when you need someone to grow with your organisation, when the role requires institutional knowledge that takes time to build, or when the position is too senior or specialised to fill through a temp arrangement.
When permanent placement makes sense
- Core roles: Positions that are central to your operation and need consistent, experienced people — supervisors, skilled tradespeople, key administrative staff.
- Roles requiring investment: If you plan to invest significantly in training and development, a permanent hire protects that investment.
- Specialised or certified positions: Roles that require specific licences or certifications that are difficult to source on short notice.
The temp-to-permanent pathway
Many employers use a temp-to-permanent arrangement as a structured trial period. The worker starts on the agency's payroll, and after a defined period — typically 90 to 520 hours, depending on the arrangement — the employer has the option to hire them directly. This reduces the risk of a poor permanent hire and gives both parties time to assess fit before committing. If you are considering this model, clarify the conversion terms with your agency upfront, including any conversion fee and the minimum hours required before conversion.
A practical framework for deciding
Ask yourself these questions for each role you need to fill:
- Is this a permanent need or a temporary one? If you are not sure, temporary is the lower-risk starting point.
- How much does demand for this role vary? High variability favours temporary staffing.
- How much institutional knowledge does the role require? High knowledge requirements favour permanent.
- What is the cost of a bad hire? For senior or specialised roles, the cost is high — a thorough permanent placement process is worth the investment.
