A vendor sends you workers and an invoice. A partner shares responsibility for whether those workers succeed and stay. That distinction sounds like soft language until a placement fails during your busiest week. The vendor’s incentive ends when the worker walks through your door; if that worker quits on day three, the vendor’s answer is to start a new search and a new invoice. A partner’s incentive runs through retention and output, because their model and their reputation depend on the placement actually working.

That is why the question deserves real weight rather than being treated as a procurement formality. The agency you choose is not just filling today’s gap; it is either absorbing the risk, the turnover, and the compliance exposure that come with a contingent workforce, or quietly transferring all of it to you. Getting that answer right is one of the higher-leverage decisions an operations leader makes, and it is almost always cheaper to get right at the start than to unwind after a placement has already failed on your busiest day.

Most employers cannot tell which one they have until something breaks, and by then the cost has landed on their floor. The six questions below surface the answer before that happens. They are deliberately concrete, because a partnership is proven in specifics: a licence number, a fill-rate figure, a site visit, a signed responsibility split, a replacement guarantee, and a plan for your peak. This matters across all major Canadian cities, and it matters more now that the rules around staffing have tightened.

The distinction is not academic. Over a year, the gap between a partner and a vendor shows up as the difference between roles filled and shifts run short, between a compliance file that is complete and one that is a liability, and between a workforce that stays and one that churns. None of that appears on the invoice, which is exactly why it is worth diagnosing before you sign rather than after a bad season has made the answer obvious.

Why the Distinction Has Real Teeth Now

A temporary help agency is a business that employs people to assign them to its clients on a temporary basis, and in Ontario those agencies must now hold a licence to operate. Since 1 July 2024, clients are also prohibited from knowingly using an unlicensed agency, which moved part of the compliance burden onto the employer using the service. The agency you choose is no longer just a sourcing decision; it is a risk decision, and that is precisely where a partner behaves differently from a vendor.

The tightening is not only legal. The labour market for industrial roles has stayed competitive even as the wider economy cooled, which means the agencies that can actually deliver workers have leverage and the ones that cannot have excuses. Put those two shifts together, real licensing risk on one side and genuine scarcity on the other, and the cost of choosing wrong rises sharply. A vendor that was merely inefficient in a loose, unregulated market becomes a liability in a tight, licensed one.

6 Questions That Reveal the Truth

1. Does Your Agency Hold a Valid Licence, or Are You Carrying Their Risk?

Why it matters. A client who knowingly engages an unlicensed temporary help agency commits an offence under the Employment Standards Act, with penalties that escalate from 15,000 to 25,000 to 50,000 dollars for repeat contraventions. That exposure is legally yours, not just the agency’s, so the licence is the first thing a partner makes easy to verify.

What to ask. Ask for the licence number directly. A partner volunteers it and points you to the public register; a vendor gets evasive. You can check any agency yourself through the Ontario temporary help agency licence search and read the framework on the Ontario licensing page. Evasiveness here usually tells you how the rest of the relationship will go.

In practice. A partner hands you its licence number in the first conversation, often before you ask, and treats your verification as reassurance rather than friction. A vendor answers a licence question with a pause, a we will send that over that never arrives, or a reassurance that you do not need to worry about it. In a regime where the offence is yours to commit, that difference is the clearest early read you get on how an agency treats the risks that land on your side.

2. Can Your Agency Tell You Its Fill Rate and Retention?

Why it matters. A partner measures outcomes; a vendor describes effort. Fill rate is the share of your open roles an agency actually fills within an agreed timeframe, and retention is how long those workers stay. A vendor talks about how many resumes it sent and how tight the market is, which are inputs, not results you can run a shift on.

What to ask. Ask for the numbers and then ask them to go into a service level agreement, a written set of commitments such as fill rate, time to fill, and response times, with consequences if they are missed. A partner agrees to be measured and reviews the figures with you. A vendor resists, because measurement is where the gap between effort and outcome becomes visible.

In practice. A partner opens with a number and a commitment: here is the fill rate we have held for clients like you, here is the time to fill we will target, and here is what happens if we miss. A vendor keeps the conversation on effort and, asked for retention data, says every client is different. Both can be true, but only one of them gives you something to manage against, and only one is willing to be wrong in writing.

3. Has Your Agency Ever Seen Your Floor?

Why it matters. The fit between a worker and an industrial role depends on things that never make it onto paper: the real pace of the line, the noise, the temperature, how far the picker walks in a shift. An agency that has stood on your floor understands what a good fit means in your operation. One that has never visited is matching keywords and hoping.

What to ask. Ask whether they will visit before placing volume. A partner walks the floor, meets the supervisor, and adjusts its screening to your reality, which shows up as lower early turnover. A vendor will quote for roles it has never seen and treat every mismatch as your problem to absorb.

In practice. A partner treats the first site visit as part of the quote, not a favour, and weeks later still remembers that your afternoon shift runs cold and your pick rate climbs after six. A vendor sends a rate card and a stack of resumes and, when the placements churn, explains that industrial work is just high turnover. The visit is cheap; what it tells you about how the agency thinks about fit is not.

4. Who Carries Payroll, Deductions, and Coverage, and Is It in Writing?

Why it matters. For temporary placements the agency is usually the employer of record, the legal employer responsible for payroll, source deductions, and statutory obligations even though the worker performs the job at your site and under your direction. When that split is left vague, gaps in responsibility surface at the worst possible moment, after an injury or a pay dispute.

What to ask. Ask, in writing, who maintains workplace safety coverage and how safety duties are shared, and confirm it against your obligations as the site operator through WSIB for businesses and the broader Employment Standards Act. A partner welcomes that clarity because it protects both of you; a vendor leaves it fuzzy, which means the risk quietly defaults to you.

In practice. A partner puts the split in writing before the first shift and raises the awkward scenarios early, because it would rather resolve them on paper than in a dispute. A vendor leaves the contract silent on the hard cases and assumes the gaps will never matter, which holds right up until an injury or a misclassification turns a quiet ambiguity into a bill. Clarity costs a conversation; ambiguity costs a claim.

5. When a Placement Falls Through, Who Owns It?

Why it matters. The moment a placement fails is the most reliable test of the relationship. Every agency looks good when the worker shows up and performs; the relationship is defined by what happens when the new hire no-shows on day two. A partner moves quickly to replace the worker and absorbs the cost. A vendor treats the failure as a fresh transaction and bills you again.

What to ask. Ask exactly what happens when a placement does not work out, and look for a defined replacement guarantee with a clear period and process. The first failed placement is also where the hidden costs of a vendor relationship appear: lost production, supervisor time spent retraining, and overtime your existing crew absorbs while the seat sits empty. Listen for whether the answer protects you or protects their invoice.

In practice. You learn more about an agency in the hour after a placement falls through than in the entire pitch that won the contract. A partner already told you the guarantee period, how fast a replacement arrives, and who absorbs the cost; a vendor improvises after the fact, often with a fresh fee attached, because nothing in the arrangement made the outcome its problem. The failed placement is the real audition.

6. Does Your Agency Plan for Your Peaks?

Why it matters. A partner builds a pipeline ahead of demand; a vendor reacts to a requisition after the pressure has hit. Canadian industrial demand is seasonal and sharp, and the labour market stays tight even when headlines cool. Statistics Canada’s Job Vacancy and Wage Survey has shown the vacancy rate in transportation and warehousing near 2.9 percent, so the workers you need are rarely available on demand.

What to ask. Ask whether they will sit down before your busy season, map your likely volume, and pre-screen candidates so they are ready when you need them. A partner asks about your next quarter, your seasonal pattern, and your growth plans. A vendor waits for the phone to ring, by which point it is already weeks behind.

In practice. A partner books the planning conversation before your season starts, builds a bench of pre-screened candidates, and checks in as your volume climbs so you are never sourcing from zero under pressure. A vendor waits for the requisition, then competes for the same scarce workers as everyone else who also waited, and hands you the delay and overtime as the cost of doing business. Planning ahead is the difference between filling a peak and surviving one.

The Bottom Line

The cost of a vendor relationship is rarely on the invoice; it is in the turnover, the risk, and the scrambles it leaves you to absorb. Run your current agency through these six questions and answer honestly. Their absence does not make an agency dishonest, but it does mean you are buying a transaction, and a transaction priced like a relationship is the most expensive arrangement of all. A partner clears this diagnostic:

None of these six tests requires a consultant or a long audit. You can run them in a single meeting, and the agency’s willingness to answer plainly is itself the result: a partner welcomes the questions because it already lives the answers, while a vendor grows vague exactly where specifics would expose it. The cost of asking is an hour of conversation; the cost of not asking is a season of turnover you could have seen coming.

Frequently Asked Questions

What is the difference between a staffing vendor and a staffing partner?

A vendor supplies workers for a fee and its responsibility largely ends at placement, while a partner shares accountability for whether those workers succeed and stay. A partner measures outcomes, signs up to service levels, absorbs the cost when a placement fails, and proves its compliance, including a licence you can confirm through the Ontario licence search. A vendor competes mainly on price.

What questions should I ask a staffing agency before signing?

Ask for their licence number, their fill rate and retention figures, whether they will visit your site, how payroll and safety responsibilities are split, their replacement guarantee, and how they plan for seasonal peaks. Start with the licence, which you can verify on the Ontario licence search. The specificity of the answers tells you whether you have a partner or a vendor.

Is it legal to use an unlicensed staffing agency in Ontario?

No. Since 1 July 2024, temporary help agencies and recruiters in Ontario must be licensed, and clients are prohibited from knowingly using an unlicensed one. Doing so is an offence for the client, with penalties that rise to 50,000 dollars for repeat contraventions. Verify any agency through the Ontario licence search.

What is a good fill rate for a staffing agency?

A strong agency consistently fills a high share of your roles within the agreed timeframe and will commit to a target in a service level agreement. The exact figure depends on role and market, and the Statistics Canada Job Vacancy and Wage Survey shows vacancies stay persistently open, so the key signals are whether the agency measures fill rate at all and whether it will be held to it.

Should I choose a staffing agency based on price?

Price matters, but the lowest markup often hides the highest total cost once turnover, risk, and re-hiring are counted, and a cut-rate unlicensed agency can expose you to penalties under the Ontario licensing rules. A slightly higher rate from a partner that backs its placements usually costs less over a season. Compare all-in cost and accountability, not just the hourly markup.

How do I switch staffing agencies without disrupting my operation?

Run your current agency through the six questions, verify any prospective partner on the Ontario licence search, then brief them on your roles, volumes, and seasonal pattern so they can build a pipeline before you transition. A good incoming partner plans the changeover around your schedule and pre-screens candidates so coverage never drops.

Questions Employers Ask When Evaluating Staffing Agencies

How does a staffing agency work and what does it cost?

A staffing agency recruits, screens, and places workers, and for temporary placements it is usually the employer of record handling payroll, source deductions, and workplace coverage. Pricing is typically a markup on the pay rate for temporary roles, or a one-time fee for permanent hires. Trimax Employment works to a clear rate so you can compare the all-in cost against hiring directly.

What should I look for in a staffing agency in Canada?

Look for relevant industry experience, a real screening process, transparent pricing, and proof of compliance such as a valid licence where one is required. Ask how they verify skills and references and how fast they can fill roles. Trimax Employment serves employers across all major Canadian cities and is happy to walk through its screening and compliance in detail.

What is the difference between a temp agency and a recruitment agency?

A temp agency supplies workers for short-term or flexible assignments and usually stays the employer of record. A recruitment agency finds candidates for permanent roles and hands them to the client, who employs them directly. Many do both. Trimax Employment offers temporary, temp-to-permanent, and direct placement so the arrangement can match the role.

Who is responsible for safety and compliance for temp agency workers?

Responsibility is shared. The agency, as employer of record, handles payroll and many statutory obligations, while the client controls the worksite and must provide a safe environment, training, and supervision under occupational health and safety law. Trimax Employment sets clear expectations with clients on safety and supervision before workers start.

How do I know if a staffing agency places quality candidates?

Ask about the screening process, fill rate, retention of placed workers, and how the agency handles a placement that does not work out. Quality agencies measure these, share them, and back placements with a replacement guarantee. Trimax Employment reports on fill rate and retention and stands behind its placements so you can judge quality directly.
