About
Truck and transport mechanics keep heavy vehicles safe and on the road. They diagnose engine, brake, steering, electrical and drivetrain problems, carry out repairs and do scheduled maintenance. Much of the work is on diesel-powered trucks, tractor-trailers and buses.
The certificate of qualification is issued by the apprenticeship authority in each province or territory. When you also pass the interprovincial Red Seal exam, your certificate carries the Red Seal endorsement. That endorsement is recognised in every province and territory, so it makes it easier to move and work across Canada. It is a strong credential for jobs such as diesel mechanic and diesel heavy vehicle repair technician.
How to get it
Find a sponsoring employer
Most people enter the trade as an apprentice. You need an employer who will hire you, supervise your work and help you learn on the job.
Register as an apprentice
Sign up with the apprenticeship authority in your province or territory. They will track your progress and tell you what training you need.
Complete paid on-the-job training
You work in a shop under a certified mechanic and log your hours. This is where you build most of your hands-on skills over several years.
Attend technical training
You go to classroom and shop training at a college or training centre, usually in blocks of study. It covers theory, safety and the systems found in modern heavy vehicles.
Pass the certification exam
When you have finished your training and work experience, you write the exam for your certificate of qualification. If you pass the interprovincial exam, you earn the Red Seal endorsement.
Other ways in
Experienced mechanics who have worked in the trade without an apprenticeship may be able to challenge the exam. Check with your provincial or territorial apprenticeship authority to see if you qualify.
The exam
The Red Seal exam is a written, multiple-choice exam. It covers the full range of the trade, including engines, fuel and exhaust systems, brakes, suspension, electrical systems, drivetrains and safety practices. Study your technical training materials and practise with sample questions before you sit it. If you do not pass, you can usually try again after a waiting period set by your apprenticeship authority.
Licensed by each province
Each province and territory issues this itself, under its own rules. Compulsory in: Nova Scotia, Ontario, Alberta. Each province and territory issues its own certificate and sets its own rules. In Nova Scotia, Ontario and Alberta, you must be certified or registered as an apprentice to work in the trade. In other places, certification is voluntary or not offered, but employers often still prefer it. The Red Seal endorsement is recognised everywhere, so it helps you work in a new province without starting over.
Keeping it
Renewal rules depend on where you live. In some provinces, the certificate stays valid as long as you remain in good standing. In others, you may need to renew it or pay a fee on a regular schedule. Check with your provincial or territorial apprenticeship authority so your certificate does not lapse.
