Red Seal Certification in Ontario: How to Get It

Key Takeaways

• In Ontario, the Red Seal is earned by passing the certifying exam for a Red Seal trade. Skilled Trades Ontario then issues a Certificate of Qualification with the Red Seal endorsement.
• There are three main routes to certificate eligibility: apprenticeship completion, the trade qualifier route through a Trade Equivalency Assessment, and the internationally trained route using the same assessment process.
• Trade qualifiers and internationally trained workers must prove both competency and work experience equal to the total Ontario apprenticeship training time for their trade.
• Exam eligibility must be confirmed before booking. Candidates need an Authorization to Test Letter, and the Red Seal exam has a 70% pass mark.
• Costs vary by route. The Trade Equivalency Assessment is $235 + HST, the exam is $150 + HST, and eligible apprentices who completed on or after January 1, 2025, receive their first exam attempt free.
• After passing, you receive an Ontario Certificate of Qualification with the Red Seal endorsement, which is recognized across participating provinces and territories.

In Ontario, you get the Red Seal by passing the certifying exam for a Red Seal trade. Skilled Trades Ontario (STO) then issues a Certificate of Qualification (C of Q) with the Red Seal endorsement. There is no separate Red Seal application to fill in. For the 51 Red Seal trades designated in Ontario, the certifying exam is the Interprovincial Red Seal exam, and STO's exam page uses that exact wording.

This guide is for journeypersons and late-stage apprentices in Ontario, including experienced workers and internationally trained tradespeople who want to know how to get Red Seal certification in Ontario without guessing at the paperwork. Three routes lead to the same exam: apprenticeship completion, the trade qualifier route through a Trade Equivalency Assessment, and the internationally trained route, which uses the same assessment with foreign work records.

Below you will find the hours STO expects for popular trades, the documents each route needs, the booking steps in the STO Portal, every fee with its source, and what happens once you pass. Every number in this article was checked against Skilled Trades Ontario pages on September 25, 2026. Fees and required hours can change, so check the linked STO page before making any payment.

Step 1: Who Issues the Red Seal Certificate in Ontario and Where to Apply

Skilled Trades Ontario is the Crown agency that registers apprentices, delivers certifying exams and issues Certificates of Qualification. It replaced the Ontario College of Trades on January 1, 2022, so if you find older forms or advice that still name "the College", the process now belongs to STO.

Everything runs through one place: the STO Portal. Your account holds your STO ID, your payments, your Completion Form and, since 2025, your exam booking. STO took over exam scheduling from the Ministry's apprenticeship offices in April 2025 and now runs exam day itself, including on-site identity checks.

Red Seal trades in Ontario: 51 of 144. Ontario has 144 prescribed trades under the Building Opportunities in the Skilled Trades Act, 2021, and 51 of them carry the Red Seal designation. Whether a trade has Red Seal status in Ontario matters because it determines which exam you write: a Red Seal trade uses the interprovincial exam, a provincial trade uses an Ontario exam that stops at the provincial border.

To confirm your trade, open its page in the Trades Information section on skilledtradesontario.ca. A Red Seal trade page shows a "Red Seal trade" label right under the trade description. No label means the trade is provincial, and Ontario doesn't offer a Red Seal endorsement.

The national list of Red Seal trades on the Red Seal website also shows 51 for Ontario.

Step 2: Choose Your Route to the Red Seal Certificate in Ontario

Table 1: Routes to Red Seal Certificate in Ontario

Source: STO exam scheduling and TEA pages.

Route 1. Apprenticeship Completion

This route is for apprentices who have logged the full hours and finished every in-school level for their trade. Before you submit the Completion Form, check two things. Every on-the-job section of your Training Standard logbook must be signed by your sponsor, and you need the notice of completion of schooling requirements that STO sends once your last level is recorded. Missing signatures are the usual reason a completion stalls, and a sponsor who has closed the business is hard to reach afterward.

Submit the Apprenticeship Completion Form through the STO Portal; both you and your sponsor sign it. STO reviews the form, mails your Certificate of Apprenticeship, and, in trades with a certifying exam, automatically issues a Provisional Certificate of Qualification valid for one year. In compulsory trades, that provisional certificate keeps you legal on site while you prepare.

Apprentices whose training agreement was completed on or after January 1, 2025, do not pay for their first exam attempt; STO applies the waiver to the account automatically. Once eligibility is confirmed, the Authorization to Test Letter arrives by email, and you can book your exam.

Route 2. Trade Qualifier (Work Experience Hours)

If you are searching for how to challenge the Red Seal exam in Ontario, the answer is the Trade Equivalency Assessment. This route is for people with experience gained anywhere in Canada who do not hold an Ontario C of Q or an equivalent authorizing certificate from another province. STO calls these applicants trade qualifiers.

The TEA decides one thing: whether you may challenge the certifying exam. STO asks for two kinds of proof, and both must be sufficient and verifiable. First, competency in the skills listed in the Training Standard. Second, experience in the trade at least equal to the total training time of the Ontario apprenticeship program, counting both on-the-job and in-school hours. For an electrician, that means 9,000 hours of experience; for a cook, 6,000.

Evidence usually includes employer letters on letterhead, pay records, tax documents, and references you can contact. Read the STO Application Guide, then complete the Application Form. The same TEA assesses Canadian Forces experience using military records.

Two cautions. If you already hold a trade certificate from another province, do not start with the TEA. Check the Recognized Canadian Certificates process first because a verified certificate gets you an Ontario C of Q with no exam and no assessment, and ignore any "1.5 times the hours" rule you may have seen for other provinces. Ontario measures against the trade's own total training time, nothing more.

If STO does not approve your application, you can apply for a reassessment with new evidence for $100 + HST.

Route 3. Internationally Trained Tradespeople

Tradespeople trained outside Canada use the same Trade Equivalency Assessment, with the same $235 + HST fee and the same two requirements: competency against the Ontario Training Standard and experience at least equal to the trade’s total training time. The difference is the paperwork. Foreign work records must be verifiable, such as translated employer letters, licences or certificates from the country where you trained, and references STO can contact.

Plan for the exam language early. STO offers certifying exams in English or French only. An interpreter or translator is available only as an accommodation supported by medical documentation; low English or French proficiency alone does not qualify. You may ask to bring your own foreign language dictionary, but it must be a word-for-word translation dictionary with no definitions, and it will be inspected before and after the exam.

WorkUgo's credentialing guidance walks through how STO reads foreign experience and how to organize records so the assessor can match them to the Training Standard. WorkUgo does not provide immigration advice; questions about status, permits or settlement belong with Immigration, Refugees and Citizenship Canada and the Ontario Immigrant Nominee Program.

Step 3: Check Your Hours and Prepare Your Documents

Red Seal certification requirements in Ontario start with hours, and the hours belong to the trade, not to the province as a whole. STO's Registrar sets them under section 14 of the Building Opportunities in the Skilled Trades Act, 2021. Apprentices must log them; trade qualifiers must show equivalent experience against the same total.

Table 2: Ontario Apprenticeship Hours for Popular Red Seal Trades

Hours vary by trade, so open the STO page for your trade rather than relying on a workmate's numbers. Other provinces run different totals for the same Red Seal trade. For example, British Columbia and Alberta do not use Ontario's 9,000-hour figure for plumbers.

Documents checklist:

• STO Portal account and your STO ID number
• Apprenticeship Completion Form, signed by you and your sponsor (apprentices)
• Trade Equivalency Assessment Application Form, prepared with the Application Guide (experienced and internationally trained workers)
• Verifiable evidence of hours and competency against the Training Standard: employer letters, pay records, references
• A copy of your certificate (Recognized Canadian Certificates route)
• Exam accommodation form and supporting medical documentation, if needed
• Government photo ID for identity verification on exam day

Step 4: Book and Take the Red Seal Exam in Ontario

Eligibility comes first: either a Certificate of Apprenticeship or a TEA approval letter. Trade qualifiers pay the Red Seal exam fee of $150 + HST on the STO Portal; apprentices covered by the 2025 waiver skip this step for the first attempt. After payment or waiver, STO emails the Authorization to Test Letter. Nothing can be booked without it.

Here is how to book the Red Seal exam in Ontario once the letter arrives:

1. Sign in to the STO Portal, or create an account with the email STO has on file.
2. Select Examinations at the top of the page.
3. Enter your STO ID number.
4. Click your name and choose the exam type.
5. Answer the accommodation question; if you need one, stop and call STO instead.
6. Pick a date, time and location.
7. Add to cart, review the selection, and select Book now.
8. Watch for the confirmation email.

Request accommodations before you book, not on exam day. Some requests require a signed assessment or letter from a qualified health professional, and STO cannot approve a request without it. The accommodation form goes to [email protected].

Red Seal exam locations in Ontario are college campuses plus STO headquarters in Mississauga, grouped into four regions: Central, Eastern, Northern and Southwest. As of September 2026, the list includes 24 sites, from Centennial and Humber in the Toronto area to Algonquin in Ottawa, Confederation in Thunder Bay, and St. Clair in Windsor. Several sites deliver the exam online through the rsexam.ca system; if yours does, you'll receive an account activation email 7 to 14 days before the exam.

The Red Seal exam Ontario candidates write is the same interprovincial paper used in every participating province. It runs up to four hours, uses multiple-choice questions with four options, and has a 70% pass mark. Check your trade page for extra requirements before you book. Welders, for example, must pass a practical assessment before the written exam. STO issues the C of Q with Red Seal endorsement only after both are completed.

STO sends Red Seal exam results and next steps after the exam. If you fail, you must wait 30 days before retaking, and each additional attempt requires a new $150 + HST payment.

Step 5: What Happens After You Pass

Table 3: What You Receive After Passing

Source: STO Certificate of Qualification page

Passing the certifying exam in a Red Seal trade earns one document, the C of Q, with the Red Seal endorsement printed on it. People sometimes ask for a Red Seal license. In Ontario, that document is the C of Q, and it is the endpoint of trade certification. Apprentices who arrive through the Completion Form receive it as the outcome of the exam. Trade qualifiers pay an issuance fee first, which STO mentions on the TEA page but doesn't publish the amount. STO redesigned the certificate in November 2023; older certificates stay valid.

Show the C of Q to your employer and keep the wallet card on you. In a compulsory trade, you must renew every year for $60 + HST, and the Public Register updates with your new expiry date once the payment clears. In other trades, the certificate never expires.

Moving to another province is where the endorsement earns its keep. The Red Seal certification Ontario issues is the same interprovincial credential that every other participating province recognizes under labour mobility rules, so a Red Seal plumber can apply for the Alberta or Nova Scotia certificate through verification rather than a new exam. Each province sets its own fees and paperwork, so contact its apprenticeship authority before you move.

Red Seal Certificate Costs in Ontario at a Glance

Table 4: Red Seal Certificate Costs in Ontario

So what does Red Seal certification cost in Ontario in total? For an apprentice who completed after January 1, 2025, and passes the first time, nothing beyond existing apprenticeship costs. For a trade qualifier who passes the first time, $235 for the assessment plus $150 for the exam comes to $435.05, including HST, plus the C of Q issuance fee (confirm with STO).

On the exam fee for apprentices: CLAC reported in December 2024 that Ontario would remove it in 2025. STO's exam scheduling and apprenticeship completion pages now confirm the waiver for apprentices who completed on or after January 1, 2025, on their first attempt. The $150 + HST figure still applies to trade qualifiers, to apprentices who finished earlier, and to every retake. The waiver covers the written exam only.

How to Prepare for the Red Seal Exam in Ontario

Start with two documents. The Red Seal Exam Breakdown for your trade, published on the Red Seal website, shows how many questions come from each major work activity. For example, the Cook exam draws 13 of its 150 questions from hygiene, sanitation, and safety. The Ontario Training Standard lists the skills STO expects you to have signed off. Where the two overlap, study those areas most closely.

STO publishes a general Exam Preparation Guide, updated in June 2026, with pacing tips and printable planning sheets. The Red Seal website adds official sample questions in the same format as the real exam: one stem, four options, one correct answer. Both are free.

Then practise for the Red Seal test under time. Four hours for up to 150 questions works out to about 96 seconds per question, and candidates who have never worked at that pace tend to find out on exam day. Work through timed sets, mark every wrong answer, and go back to the Training Standard for the section behind each miss. Twenty free Red Seal practice questions on WorkUgo's exam prep platform will show where you stand before you commit to a full study plan.
