Quick answer: before you sign a staffing agency for the 2026 holiday peak, ask ten questions that expose cost, risk and reliability: its Ontario licence number, its WSIB clearance, what is inside the bill rate, how holiday pay and overtime are billed, its real fill and show-up rates, where its candidates come from, what safety training happens before day one, what a permanent conversion costs, who pays when an assignment ends early, and how it handles postings and records. Under Ontario law, several of these answers decide whether you share liability for the agency’s mistakes.

Most agency selection for Black Friday and the Christmas rush happens in a hurry, on price per hour. That is understandable in October, but it is how employers end up with a cheap rate, a 75% show-up rate on Cyber Monday and a surprise invoice for holiday pay in January. The ten questions below come with the 2026 numbers and the legal reasons behind them. For a shortlist of providers to put them to, see our 7 best staffing agencies for Q4 peak hiring.

Why Agency Choice Matters More in Peak 2026

Three things changed the agency decision for this holiday season. First, Ontario’s licensing regime is now fully in force, so the question is no longer whether an agency is reputable in general but whether it holds a current licence that you can verify, because using an unlicensed agency knowingly is itself prohibited. Second, cost pressure moved upward on October 1, when the general minimum wage rose to $17.95, and every agency bill rate quoted before that date needs to be re-checked against the new floor. Third, the January 2026 job posting rules mean the postings an agency runs on your behalf carry your compliance exposure as well as theirs.

At the same time, the cost of a wrong choice is concentrated into a very short window. With Black Friday on November 27 and Cyber Monday on November 30, a show-up problem or a payroll dispute in the first three weeks of December cannot be fixed by switching agencies, because nobody else has trained crews ready. That is why the questions below focus on evidence you can check in October, not promises you can only test in December.

The 10 Questions to Ask a Staffing Agency Before Peak

1. “What is your Ontario licence number?”

Since July 1, 2024, every temporary help agency and recruiter operating in Ontario must hold a licence, and clients are prohibited from knowingly using an unlicensed agency, according to the Government of Ontario’s licensing page. To be licensed, an agency pays a $750 application fee and posts a $25,000 irrevocable letter of credit that the Director of Employment Standards can draw on to repay wages owed to workers, as described in the ESA licensing chapter.

Worked example: checking a licence on the public registry takes about two minutes. Skipping it can cost far more, because under the ESA temporary help agency rules the client can be jointly and severally liable with the agency for unpaid regular wages, overtime and public holiday pay. If an unlicensed agency disappears owing 50 workers two weeks of wages at $21.00 an hour, that is up to $84,000 of exposure. The insight: the licence is not paperwork, it is your first layer of wage-default insurance.

2. “Can you send a current WSIB clearance certificate?”

A WSIB clearance certificate confirms that the agency’s WSIB account is open, properly classified and paid up. Under the WSIB clearance certificate policy, when a principal holds a valid clearance, the WSIB waives its right to hold that principal liable for the contractor’s unpaid premiums for the validity period. Without one, the principal may be liable for the contractor’s WSIB obligations up to the value of the labour portion of the contract, as the WSIB clearance FAQ explains.

Worked example: a 10-week contract for 50 workers at $21.00 an hour carries $420,000 in labour. At the 2026 WSIB average rate of $1.23 per $100, that is about $5,166 in premiums, and potentially more at a warehousing class rate. The insight: ask for a fresh clearance at signing and again before each invoice cycle in November and December, because certificates are time-limited and an agency can fall out of good standing mid-peak.

3. “What exactly is inside your bill rate?”

A bill rate has three layers: the worker’s wage, statutory costs the agency must pay as employer, and the agency’s recruiting, payroll, insurance, overhead and margin. In 2026 the statutory layer includes CPP at 5.95% (per the CRA CPP page), EI at 2.28% (per the CRA EI page), WSIB, 4% vacation pay and public holiday pay. On a $21.00 wage over a 10-week peak, those items add about $4.04 per hour worked.

Worked example: at a 1.40 multiplier, a $21.00 wage bills at $29.40. Subtract $21.00 and $4.04 in statutory costs and only $4.36 an hour (about 15% of the bill) is left for everything else the agency does. The insight: compare quotes on what is left after wage and statutory costs, not on the markup percentage. An agency quoting 1.30 may be squeezing the worker’s wage to protect margin, which shows up later as no-shows (see question 6).

4. “How do you bill public holiday pay and overtime?”

Three public holidays fall in the 2026 peak: Christmas Day (Friday, December 25), Boxing Day (Saturday, December 26) and New Year’s Day (Friday, January 1, 2027). Under the ESA public holiday rules, holiday pay is regular wages from the prior four work weeks plus vacation pay, divided by 20, and overtime at 1.5 times starts after 44 hours. The agency pays these as employer, but you pay for them through the invoice, and the ESA makes clients jointly liable if they go unpaid.

Worked example: holiday pay for 50 workers earning $840 a week is $174.72 each per holiday, or $26,208 for three holidays. Billed at a 1.40 markup, that becomes $36,691, a $10,483 difference. The insight: negotiate holiday pay and overtime premium billed at cost or at a reduced markup in writing now, because once Cyber Week overtime starts, you have no leverage.

5. “What were your fill rate and show-up rate last peak?”

Peak hiring competes with national shippers for the same people. Statistics Canada’s Q2 2026 job vacancy survey counted 510,200 vacancies nationally, and vacancies in trades, transport and equipment occupations were up 6.6% from a year earlier to 98,600. Every agency will say it can fill your order. Ask instead for last year’s Q4 numbers: percentage of ordered positions filled by the start date, day-one show-up rate and average time to back-fill a no-show.

Worked example: order 50 workers with a 92% show-up rate and you get 46. Four empty spots on 8-hour shifts for a 5-day week is 160 lost labour hours, the equivalent of one full extra crew-day in Cyber Week. The insight: ask the agency to over-book by about 10% for the first two weeks, with the right to release extras at no charge after the first four hours.

6. “Where do your candidates come from, and what will you pay them?”

The labour market is mixed going into peak: the August 2026 Labour Force Survey showed employment down about 42,000 with unemployment steady at 6.4%. More people are available, but reliable warehouse workers still choose between offers. The Job Bank Toronto-region median for material handlers is $21.00, while the median for order pickers sits at the $17.95 minimum. Your agency’s sourcing channels and the wage it offers decide which of those pools you are drawing from.

Worked example: an agency that pays $18.25 to protect its margin on a tight bill rate will attract candidates who leave the moment a $20 offer appears in December. The insight: ask the agency to state the worker pay rate in the contract, and ask how many active, already-screened candidates live within a 30-minute commute or transit ride of your site, especially for overnight shifts in Brampton, Mississauga or Vaughan.

7. “What safety training happens before day one, and who verifies equipment competency?”

The Institute for Work & Health found that workers in their first month face more than three times the risk of a lost-time injury compared with workers employed over a year. Every Ontario worker must complete basic awareness training, available free through the Worker Health and Safety Awareness in 4 Steps program. For forklifts, Ontario’s lift truck competency guideline requires operators to be trained and to demonstrate competency on the equipment they will use.

Worked example: an agency that completes the 4 Steps program, a lifting and PPE briefing and a ticket check before day one saves you roughly two paid hours per worker, or about $2,100 across 50 workers at $21.00, and gets them productive faster. The insight: write into the contract who delivers site-specific orientation and who evaluates forklift competency on your trucks, because a ticket from another site does not prove competency on your reach trucks.

8. “What does it cost to hire a worker permanently?”

Peak is the cheapest audition you will ever run. Under the ESA temporary help agency rules, an agency cannot stop a client from hiring an assignment employee directly, and can only charge the client a conversion fee during the six months starting on the worker’s first day with that client. After six months, no fee is allowed. The agency also cannot charge the worker anything for being hired.

Worked example: a worker who starts with you on October 19, 2026 can be converted fee-free from April 19, 2027. If you want them sooner, a sliding fee (for example, falling by a fixed amount each month) is a fair negotiation. The insight: agree the conversion terms in writing now, because your best peak workers will get offers elsewhere in January. Our temp-to-perm hiring guide covers how to run the evaluation.

9. “Who pays if we end an assignment early?”

The ESA requires an agency to give one week’s written notice of termination of assignment, or pay in lieu, when an assignment had an estimated term of three months or more and ends before that term. Notice is not required if the agency offers the worker another assignment of a week or more during the notice period. Most agencies pass this cost through to the client, so it belongs in your contract discussion.

Worked example: if you order 50 workers with an estimated term of October 5 to January 8 (just over three months) and cut the crew on December 4, one week of pay in lieu at $840 per worker is $42,000 that the agency may invoice to you. The insight: set the estimated term honestly, and if your volume really drops after Boxing Day, state a shorter estimated term with an extension option rather than a long one you may cut.

10. “How do you handle postings, records and audits?”

Since January 1, 2026, Ontario employers with 25 or more employees must include pay or a pay range, disclose any AI screening, state whether a vacancy exists and answer interviewed applicants within 45 days, under the ESA job posting rules. Agencies posting jobs at your site need to follow these rules too. Separately, the ESA requires both the agency and the client to record the hours each assignment employee works each day and week, and to keep those records for three years.

Worked example: if an employment standards officer asks for December hours for 50 assignment workers, you as the client must be able to produce your own record, not just point to the agency. The insight: require a weekly timesheet export in a format you can archive, and ask to see a sample of the agency’s job posting template to confirm the pay range and AI disclosure are present. Our temp agency compliance guide has a full checklist.
