Ontario Certificate of Qualification — based on Skilled Trades Ontario's official Hairstylist Curriculum Standard
About the certification
Hairstylist is a compulsory trade in Ontario, regulated under the Building Opportunities in the Skilled Trades Act, 2021 and administered by Skilled Trades Ontario (STO). It is recognized nationally as an Interprovincial Red Seal trade, but Ontario does not currently offer the Red Seal endorsement for it — candidates who pass the certifying exam receive a provincial Certificate of Qualification (C of Q) only.
Per STO's own general exam preparation guidance, candidates get up to 4 hours to write the exam (you can leave earlier if finished), and 70% is required to pass. The exam is multiple choice with 4 options per question, and STO states exams may run between 90 and 150 questions — it does not publish an exact fixed count for Hairstylist specifically, so third-party estimates of roughly 125 questions should be treated as an estimate, not an official figure.
This free practice quiz has 180 original questions across ten topic areas, consolidated from STO's official Hairstylist Curriculum Standard — Levels 1 & 2 (2012), which covers 480 hours of in-school training across 17 units. Test Me mode draws 125 questions with a 4-hour timer and a 70% pass mark to mirror the real exam's scale — your own sitting's exact count and timing may vary.

Why: Hairstylist is recognized nationally as an Interprovincial Red Seal trade, but Ontario does not currently administer the Red Seal exam for it — passing candidates receive a provincial C of Q only.
Why: Permanent waving and relaxing chemically break and reform disulfide bonds, strong sulfur-sulfur bonds within the cortex, which allows a lasting change to the hair's curl or straightness.
Why: Hair colour products are commonly grouped by how long they last: temporary coats the surface, semi-permanent partially penetrates and fades, and permanent chemically alters hair until new growth appears.
Why: Graduation, typically cut at lower to mid elevations, builds a stacked wedge of weight, while layering, typically at higher elevations, removes weight and creates more even movement.
Why: Bonding attachment methods use an adhesive, sometimes heat-activated as with keratin or fusion bonds, to fuse extension strands to natural hair near the root.
FAQ
No. Hairstylist is an Interprovincial Red Seal trade, but Ontario does not currently offer the Red Seal endorsement for it. Candidates who pass Ontario's exam receive a provincial Certificate of Qualification (C of Q) only, not a Red Seal.
Skilled Trades Ontario's general exam-format policy (which applies since Hairstylist has no separate published format) says exams run 90 to 150 multiple-choice questions, with up to 4 hours to complete and 70% required to pass. STO does not publish an exact fixed count for Hairstylist specifically, so treat 90–150 as the honest range rather than a precise number.
70% is the pass mark Skilled Trades Ontario applies to both provincial and Interprovincial certifying exams, including Hairstylist's provincial C of Q exam.
The 180-question bank is consolidated from Skilled Trades Ontario's official Hairstylist Curriculum Standard (Levels 1 & 2, covering all 17 in-school training units), STO's general exam-format guidance, and well-established cosmetology and infection-control knowledge. Every question is written fresh, not copied from any other prep site.
That mirrors the upper-middle of STO's published 90–150 question range and the full 4-hour window most Ontario trade exams allow, so practice conditions feel close to the real sitting. The exact count and timing at your own test can vary.
Yes — Hairstylist is a compulsory trade in Ontario. You generally need to complete the required apprenticeship hours (or qualify through another recognized pathway) before you're eligible to write the Certificate of Qualification exam.
