About the certification
In Ontario, Auto Body and Collision Damage Repairer is trade code 310B, a compulsory trade regulated by Skilled Trades Ontario. Apprenticeship is about 8,000 hours (7,280 on the job and 720 in school). Across Canada it is the Red Seal trade Auto Body and Collision Technician, so passing the Certificate of Qualification exam also earns the interprovincial Red Seal endorsement.
The Red Seal exam has 120 multiple-choice questions across 7 blocks. The heaviest are repairing frame and structural components (28 questions), non-structural outer body panels (24) and refinishing (22). Most questions are procedural or application scenarios, and under 10% are critical thinking. Red Seal doesn't publish the pass mark on the exam page; 70% is the standard Red Seal pass mark.
ExamHub's free 310B practice quiz has 212 original questions weighted to the real exam blocks, with an explanation and a source for every answer.

Five sample questions from the question bank, with the answer and explanation.
Why: Isocyanates have poor odour warning, and a half-mask air-purifying respirator offers limited protection against spray mist. Supplied-air respirators give a higher level of protection, and paints are applied under that protection.
Why: In a diamond condition one side of the structure has shifted forward or rearward relative to the other, so the shape becomes a parallelogram. Unequal diagonals with correct widths are the typical sign.
Why: The inverter and other components hold charge after the pack is isolated. The OEM waiting time lets that charge drain, and zero voltage is then verified with a suitable meter before touching HV parts.
Why: A fired pretensioner has used its one-time charge and the belt webbing may be stretched. Belts that have been loaded in a crash are replaced, since they cannot be relied on to restrain the occupant again.
Why: Solvents trapped under the next coat boil out later as tiny pinholes (popping) or cause dull spots. The data sheet gives the flash time for the conditions.
