Parts Technician (246A) Red Seal Exam in Ontario

Certifying authority: Skilled Trades Ontario (STO). Last checked 2026-09-10.

Certification is voluntary in Ontario

This trade is not on Ontario’s compulsory list, so you may work in it without a certificate. The Red Seal still travels across Canada as a recognised credential, and employers frequently ask for it — but in Ontario it is a qualification, not a licence.

Sample Question 1 of 3
While unloading a mixed pallet, you notice that a 20 L pail of alkaline radiator flush concentrate has split at the seam and is seeping across the dock floor toward a floor drain. Two co-workers are walking through the area with pallet jacks, and the spill kit and the SDS binder are at the far end of the dock. In what order should you deal with this?
A) Check the SDS for the hazards and PPE; stop traffic and keep people back; put on the PPE and contain the spill with the kit, starting at the drain; then report it
B) Stop traffic and keep people back; check the SDS for the hazards and PPE; report it; then put on the PPE and contain the spill with the kit, starting at the drain
C) Stop traffic and keep people back; check the SDS for the hazards and PPE; put on the PPE and contain the spill with the kit, starting at the drain; then report it
D) Check the SDS for the hazards and PPE; put on the PPE and contain the spill with the kit, starting at the drain; report it; then stop traffic and keep people back
Correct answer: C

People are protected first by isolating the area. The SDS then tells you the hazards and the PPE needed before anyone touches the product; containment and reporting follow. The other options use the same steps in the wrong order: A does 'check the SDS for the hazards and PPE' before 'stop traffic and keep people back', B does 'report it' before 'put on the PPE and contain the spill with the kit, starting at the drain', and D does 'check the SDS for the hazards and PPE' before 'stop traffic and keep people back'.

Sample Question 2 of 3
A senior customer buys a pair of wiper blades in the rain and struggles to fit them in the parking lot. Your store offers basic installation of wiper blades and bulbs at no charge when time allows, and the counter is quiet. The customer asks if someone could help. What should you do?
A) Fit the blades for them and add a labour charge, as installation is work outside the sale
B) Fit the blades for them at no charge, as basic installation is one of the store's services
C) Show them the package diagram and let them fit the blades, as staff stay at the counter
D) Fit the blades for them at no charge, but only if they also buy washer fluid today
Correct answer: B

Basic installation of wiper blades and bulbs is a no-fee value-added service, and the counter is quiet, so the blades are fitted for the customer. Charging, refusing or tying the help to another purchase goes against the store's service.

Sample Question 3 of 3
Your dealer management system requires serial numbers to be recorded for high-value assemblies such as remanufactured engines, automated transmissions and programmed control modules, from receiving through to the customer's invoice. A new receiver wants to skip the serial numbers on busy days, since the part number already identifies the item. What should you tell them?
A) Record them, as serials trace each unit for warranty, recalls and theft
B) Skip them, as the part number does the same job as the serial number
C) Record them at the physical count, instead of at receiving
D) Record them when each unit is sold, from the box at the counter
Correct answer: A

Serial numbers trace each high-value unit from receiving through stock to the customer, which supports warranty claims, recalls and loss control. A part number identifies the type, not the unit (B), and recording later (C, D) leaves a gap in the trace from receiving.
