Choosing a staffing agency can feel overwhelming, especially when several companies are offering similar services at different prices.
You might be looking for temporary employees to support a busy season, help filling a hard-to-recruit position, or a long-term partner to manage ongoing workforce needs. Whatever the situation, the agency you choose can affect your team’s productivity, hiring costs, and ability to meet business demands.
While pricing and the ability to fill open positions are important, they only tell part of the story. You also need to understand how an agency finds candidates, evaluates their qualifications, manages its responsibilities, and supports both your company and its employees.
In this guide, we’ll cover:
- What to look for when evaluating staffing agencies.
- Questions to ask before choosing a staffing partner.
- Warning signs that an agency may not be the right fit.
- How to compare staffing costs and service quality.
- Ways to build a successful long-term staffing relationship.
What Should You Look for in a Staffing Agency?
The right staffing agency should understand your hiring needs and have a clear process for meeting them.
Before signing an agreement, consider the following factors.
1. Experience with your industry and hiring needs
An agency that understands your industry may be better prepared to recognize the skills, qualifications, and working conditions required for your positions.
For example, a manufacturing company may need employees who are comfortable working in a fast-paced production environment, while a distribution centre may require candidates with specific equipment experience or availability for overnight shifts.
Industry experience can help an agency ask more useful questions and identify potential challenges before an assignment begins.
However, an agency does not necessarily need to specialize exclusively in your industry to provide good service.
Questions to ask:
- Have you recruited for similar positions before?
- What industries and types of roles do you regularly support?
- How do you learn about a company’s specific hiring requirements?
Pay attention to how the agency responds. A strong staffing partner should be interested in learning about your business rather than simply promising to send candidates.
2. A clear candidate recruitment and screening process
One of the main reasons companies work with staffing agencies is to access candidates without managing every stage of recruitment themselves.
However, not all agencies recruit and screen candidates in the same way.
Ask how potential employees are sourced, evaluated, and prepared for assignments.
Depending on the position, this may involve reviewing work experience, conducting interviews, verifying qualifications, checking references, or completing job-specific assessments.
The agency should also understand the difference between your essential requirements and the qualifications that would simply be nice to have.
For example, if you’re hiring an administrative assistant, the job title alone may not explain what the person will actually do. One company may need someone focused on customer service and scheduling, while another requires experience with invoicing and financial records and reports.
Questions to ask:
- Where do you find candidates?
- What screening takes place before someone is presented for a position?
- How do you confirm candidates understand the job requirements?
- How do you handle positions that are difficult to fill?
A clear recruitment process helps you understand what you’re paying for and how the agency approaches candidate quality.
3. Compliance, insurance, and workplace safety
For companies using temporary staffing services, compliance should be an important part of the selection process.
Employment standards, workers’ compensation, workplace safety, and agency licensing requirements can vary across Canada.
A staffing agency should understand the requirements that apply to its services and the locations where its employees will work.
It should also be prepared to discuss its insurance coverage, safety procedures, required training, and approach to workplace incidents.
Working with a staffing agency does not automatically remove your company’s workplace responsibilities. Both parties need to understand their roles.
Compliance also extends to verifying that employees are legally authorized to work in Canada.
For example, a company approached ABL Employment after discovering that its previous staffing agency had been supplying workers without the required work authorization. This exposed the company to potential legal and compliance risks, a situation that a staffing partner should never put its client in.
Questions to ask:
- What insurance and workers’ compensation coverage do you maintain?
- How do you address workplace health and safety requirements?
- How do you verify that employees are legally authorized to work in Canada?
- What information do you need about our workplace before assigning employees?
- How do you manage incidents, injuries or safety concerns?
- How do you stay current with applicable provincial requirements?
An agency that asks detailed questions about your work environment, equipment, training and safety procedures, and can clearly explain its employee verification practices, is demonstrating that it takes these responsibilities seriously.
4. Transparent pricing and billing practices
Price is often one of the first things companies compare when choosing a staffing agency.
While staying within budget matters, selecting an agency based only on the lowest quoted rate can overlook important differences in service.
For temporary staffing, an agency’s bill rate may account for employee wages, payroll-related costs, insurance, recruitment, administration, and the services included in the arrangement.
Before comparing quotes, make sure you understand what each agency provides.
Ask about additional charges, overtime, statutory holiday pay, minimum assignment requirements, and any terms that could affect your final invoice.
You should also understand how hours are recorded and approved.
For example, missing or incorrectly completed timesheets can lead to billing errors or delays. Agreeing on a timekeeping process and identifying who will approve hours can help prevent these issues.
Questions to ask:
- What is included in your quoted rate?
- How are overtime and statutory holidays billed?
- Are there additional fees or minimum requirements?
- How are employee hours tracked and approved?
- What happens if there’s a billing discrepancy?
The goal is to compare the overall value and reliability of the service, rather than focusing on the hourly rate alone.
5. Reliable communication and ongoing support
Good communication is one of the most important parts of a successful staffing relationship.
Your agency needs to understand your expectations, respond to concerns, and keep you informed when staffing needs change.
This becomes especially important in industries that operate outside regular business hours.
A warehouse running overnight shifts or a manufacturer operating on weekends may need support when an employee calls in sick, an unexpected order arrives, or an assignment needs to change.
Ask how the agency handles urgent requests and whether someone is available outside standard office hours.
Communication should also work both ways.
A staffing agency that regularly checks in with its employees may be better positioned to identify scheduling concerns, clarify expectations, and address problems before they affect an assignment.
Questions to ask:
- Who will be our main point of contact?
- What support is available during evenings and weekends?
- How do you handle urgent staffing requests or employee absences?
- How frequently will you communicate with our team?
- How do employees contact the agency when they need support?
Look for an agency that explains its communication process clearly and sets realistic expectations about response times.
6. Respectful treatment of candidates and employees
How a staffing agency treats its workforce can influence the quality of the relationship it builds with candidates.
Agencies that communicate regularly, explain job expectations, and provide support during assignments have more opportunities to understand what employees need to succeed.
Ask how the agency prepares candidates for work, handles employee concerns, and maintains relationships between assignments.
You can also look at reviews and feedback from both client companies and candidates.
Recognition and industry awards may provide additional context, but they should support, rather than replace, your evaluation of the agency’s processes.
Questions to ask:
- How do you prepare employees before their first shift?
- What support do employees receive during assignments?
- How do you respond when an employee raises a concern?
- What do candidates and client companies say about working with you?
A good staffing relationship should consider the needs of the company, the agency, and the person performing the work.
What Are the Warning Signs of an Unreliable Staffing Agency?
Knowing what to look for in a staffing agency also means recognizing when a potential partner may not be the right fit.
Some warning signs include:
- Unrealistic guarantees. Be cautious of agencies promising perfect attendance, zero turnover or that every candidate will be an ideal match. Even strong recruitment processes cannot eliminate every unexpected absence or hiring challenge.
- Unclear pricing. If an agency cannot explain what its rates include or how additional charges are handled, you may have difficulty comparing costs, or managing your budget.
- Limited interest in your workplace. An agency that does not ask about job duties, safety requirements, schedules, or working conditions may not have enough information to prepare candidates properly.
- Poor communication. Delayed responses, unclear points of contact or a lack of after-hours support can become bigger problems when staffing needs are urgent.
- Little information about screening. An agency should be able to explain how it evaluates candidates and determines whether they meet your requirements.
No staffing agency can guarantee that every assignment will go perfectly.
What matters is whether the agency has processes to reduce avoidable problems and respond when something goes wrong.
What Questions Should You Ask Before Choosing a Staffing Agency?
Once you’ve narrowed down your options, it can help to use the same questions when speaking with each agency.
This makes it easier to compare their approaches rather than relying on different sales presentations.
Staffing agency selection checklist:
- Does the agency have experience recruiting for our industry or types of positions?
- Can it clearly explain its candidate sourcing and screening process?
- Does it ask detailed questions about our workplace and job requirements?
- Can it explain its insurance, safety, and compliance practices?
- Are its rates, additional fees, and billing procedures clear?
- Does it offer communication and support that match our operating hours?
- Does it set realistic expectations about attendance, retention, and candidate availability?
- Does it have a process for addressing employee concerns and performance issues?
- Can it explain how it will measure and review the success of our partnership?
You may also want to request client references or examples of how the agency has handled similar staffing challenges.
The best choice will depend on your company’s priorities. An agency supporting occasional short-term assignments may need a different service model than one managing a large, ongoing workforce.
How Can You Build a Successful Relationship With Your Staffing Agency?
Choosing the right staffing agency is only the beginning.
Even an experienced agency needs accurate information and ongoing communication to deliver the service your company expects.
The strongest partnerships are built around shared expectations and a clear understanding of what success looks like.
Explain what the employee will actually do
Job titles do not always tell the full story.
Rather than requesting an administrative assistant, warehouse associate, or production worker based on the title alone, explain the tasks the person will perform.
Share the required skills, equipment, shift schedule, physical demands, working conditions, and who the employee will report to.
It also helps to separate essential qualifications from preferences.
For example, if a position requires basic computer skills but your company is willing to train someone on its specific software, communicate that distinction.
This gives the agency a clearer understanding of which candidates may be suitable and can prevent unnecessary limits on the candidate pool.
Give the agency a clear picture of your workplace
Whenever practical, allow your staffing partner to become familiar with the work environment before employees begin their assignments.
This may involve a workplace visit, a detailed orientation or sharing relevant information about equipment, safety requirements, and working conditions.
Your agency should understand where employees will report, what their first day will involve, and who will provide workplace instructions and supervision.
This information helps the agency communicate expectations to candidates, and prepare them for the assignment.
Share feedback early and regularly
If an employee is performing well, let your agency know.
If something isn’t working, communicate the concern as soon as possible and explain the issue clearly.
For example, saying that a candidate is not a good fit provides less useful information than explaining that the position requires stronger attention to detail, different equipment experience or greater comfort with a particular work schedule.
Specific feedback helps the agency adjust its screening process and better understand your expectations for future assignments.
The same applies to your overall experience with the agency.
Discuss what is working, where communication could improve, and whether your staffing needs have changed.
Plan ahead when possible
Not every staffing need can be predicted.
However, sharing upcoming projects, seasonal peaks, expected vacancies or changes in production volume can give your staffing partner more time to prepare.
For companies with ongoing temporary staffing needs, regular planning discussions may help the agency identify potential candidates before demand increases.
Long-term relationships can also help an agency become more familiar with your company’s culture, hiring managers and workforce requirements.
Over time, this knowledge can make future recruitment more targeted and reduce the need to explain the same requirements for every new assignment.
Agree on how success will be measured
Before beginning a staffing partnership, discuss what successful service looks like for your company.
Depending on your needs, this could include:
- How quickly open positions are filled.
- Whether candidates meet the required qualifications.
- Attendance and employee retention.
- Accuracy of timekeeping and billing.
- Communication and response times.
- Feedback from supervisors and assignment employees.
These measures should reflect the type of staffing support you’re receiving.
For example, a company using temporary employees for a short seasonal project may have different priorities than one seeking permanent employees through direct-hire recruitment.
Regularly reviewing performance gives both parties an opportunity to address challenges and improve the working relationship.
Why Does a Long-Term Staffing Partnership Matter?
When a company works with the same staffing agency over time, the agency has more opportunities to understand its operations and hiring preferences.
This can be especially valuable for businesses with recurring workforce needs.
Instead of starting from the beginning each time a position opens, your staffing partner may already know your shift schedules, required qualifications, workplace expectations, and the types of candidates who have succeeded in previous assignments.
That knowledge can support more focused recruitment and workforce planning.
A long-term relationship also creates opportunities for more useful conversations.
Rather than simply requesting a certain number of employees, your company can discuss upcoming projects, budget considerations, changes in demand, and recurring recruitment challenges.
An experienced staffing partner should be willing to offer recommendations, raise concerns, and explain when a different hiring approach may be more suitable.
However, a long-term relationship should still be evaluated on results.
Continue reviewing service quality, communication, candidate suitability, and whether the agency is meeting your changing business needs.
