Peak season gives you a short window and no margin. A warehouse, plant or finance team that needs 15 extra people in three weeks cannot run a long hiring process, and it cannot afford to guess wrong. The good news is that seasonal hiring comes down to a few traits, and you can test for each of them quickly.
Attendance matters more than the resume
A seasonal crew is built tight. When one person misses a shift, the line, the dock or the close calendar absorbs it immediately, and there is no slack week to make it up.
So screen for reliability first. Do it with questions and records, not impressions:
- Ask for availability in writing, including dates and shifts the person cannot work.
- Ask how they got to their last job and what they would do if that route failed.
- Check references with one question: would you rehire this person, and did they show up?
- Look for evidence of covered shifts, long tenure in a modest role, or steady school or volunteer commitments.
A candidate who tells you plainly what they cannot do is usually safer than one who says yes to everything.
Learning speed beats years of experience
Training windows in peak season are measured in hours or days. You do not need someone who has done the exact job. You need someone who follows a procedure the first time, asks a useful question when stuck, and is working alone quickly.
A simple way to test it in the interview:
- Ask for one example of picking up a new system or machine fast.
- Have them explain the task, how they learned it, and how long before they worked unassisted.
- Better still, teach them a small task for five minutes and watch them repeat it.
Certifications help. A valid forklift ticket or a WHMIS card saves you a day of onboarding. But treat them as a bonus. A quick learner without a ticket is often a better hire than a certified worker who resists instruction.
Safety attitude is a hiring criterion
Seasonal workers are new, hurried and often tired. That is when injuries happen. In both Canada and the US, you are responsible for training and protective equipment whether someone is on for six weeks or six years. In Ontario that duty sits under the Occupational Health and Safety Act, and in the US under OSHA requirements.
Your training covers the rules. What you are screening for is whether the person will follow them when the supervisor is not watching. Ask what they would do if they saw a spill, a damaged pallet or a missing guard. Listen for whether they would report it or work around it.
Steadiness when the plan changes
Peak means overtime, late orders, shift swaps and physical work. Some people take a change in stride, and others turn it into a problem for the whole crew.
Use a scenario in the interview. A large order lands at 3:30 pm and the afternoon crew is asked to stay two extra hours. What do they do? Strong candidates ask where help is most needed, keep a steady pace, and tell teammates what is already done. Weak answers focus on what is unfair or unclear.
This matters in office roles too. Seasonal AP clerks, order entry staff and customer service reps face the same pile-up at quarter-end or holiday volume.
Make the process match the calendar
Even good screening fails if it is slow. Strong seasonal candidates take the first decent offer, often within 48 hours.
- Decide your must-haves before posting: availability, a safety attitude and a learning check.
- Cut interviews to one short conversation plus a reference call.
- Make offers the same day where you can, with start date, shifts and pay in writing.
- Plan for a few no-shows and over-hire slightly in the first week.
- Tell strong performers early if there is a path to extra hours or a permanent role.
That last point pays back. A food manufacturer in the GTA that Traverse worked with hired over 20 people in 18 months across production, skilled trades and office roles. Temporary and short-term hires who proved reliable became a dependable pipeline for those permanent openings.
What to do next
Before your next peak, write down the three traits that matter most for each seasonal role and build one question or short exercise for each. Then set a decision deadline you can actually meet. If you would rather not run that process on top of your normal workload, a Traverse recruiter can help you screen and place seasonal and contract staff in Canada and the US.
