Introduction to AME Licensing in Canada
The Aircraft Maintenance Engineer (AME) license is the cornerstone of aviation safety in Canada. Issued by Transport Canada Civil Aviation (TCCA), the AME license authorizes qualified professionals to certify that maintenance performed on an aircraft meets the stringent standards set out in the Canadian Aviation Regulations (CARS). Without a licensed AME, no aircraft in Canada can legally return to service after maintenance.
Transport Canada recognizes three primary AME license categories — License M (Maintenance), License E (Electronics), and License S (Structures) — each with its own specialized scope, training requirements, and examination profile. These categories are defined under the TP14038E syllabus, which serves as the official regulatory framework for AME training and certification in Canada.
The AME designation is respected globally as a mark of technical excellence in aviation maintenance. Canadian AMEs are in high demand not only domestically but also internationally, thanks to bilateral aviation safety agreements that recognize Canadian credentials in many countries around the world.
License Categories: M, E, and S Explained
Choosing the right license category is the single most important decision you will make on your AME journey. Each category leads to a different career path with distinct responsibilities, work environments, and earning potential. Below is a detailed breakdown of each category.
License M — Maintenance (Airframe & Powerplant)
License M is the most common AME category and covers the maintenance of aircraft airframes and their powerplant systems. It is further divided into two ratings:
- M1 Rating — Small aircraft under 12,500 lbs MTOW, including non-turbine helicopters. M1 engineers work primarily in general aviation at flight schools, regional maintenance shops, and private hangars. The focus is on piston engines, basic electrical systems, and non-pressurized airframes.
- M2 Rating — All aircraft regardless of weight, including turbine-powered aircraft and all helicopters. M2 engineers operate at major airlines, large MROs (Maintenance Repair Organizations), and OEM service centres. The work involves turbine engines, pressurization systems, complex hydraulics, and advanced avionics integration.
License E — Electronics (Avionics)
License E covers the maintenance, testing, and certification of aircraft electronic and avionics systems. E-licensed engineers are specialists in:
- Communication and navigation systems (VHF, HF, GPS, ILS, VOR, ADF)
- Radar systems (weather radar, terrain awareness, traffic collision avoidance — TCAS)
- Flight management systems and autopilots
- Instrument systems (attitude indicators, altimeters, air data computers)
- In-flight entertainment and cabin systems
- Electrical power generation and distribution systems
License E engineers typically work in specialized avionics shops, airline maintenance bases, or MRO facilities. The avionics field is evolving rapidly with the introduction of next-generation aircraft like the Boeing 787 and Airbus A350, which rely heavily on integrated modular avionics and fly-by-wire systems.
License S — Structures
License S covers the repair, modification, and certification of aircraft structural components. S-licensed engineers are experts in:
- Sheet metal repair and fabrication (aluminium, steel, titanium)
- Composite structure repair (carbon fibre, fibreglass, Kevlar)
- Welding and brazing techniques (TIG, MIG, oxy-fuel)
- Structural inspection and damage assessment (NDT/NDI methods)
- Corrosion prevention and control programs
- Major structural modifications and repairs per Structural Repair Manuals (SRM)
Structures engineers are in high demand in both the airline world and in specialized MROs handling heavy maintenance checks (C-checks, D-checks). With the increasing use of composite materials in modern aircraft (the Boeing 787 is over 50% composite by weight), the structures discipline is more critical than ever.

Step-by-Step Pathway to Your AME License
Step 1: Meet Basic Eligibility Requirements
Before beginning the licensing process, you must satisfy these prerequisites:
- Be at least 18 years old at time of certification
- Hold a valid Transport Canada Medical Certificate (Category 1 or 3)
- Have completed secondary education (high school diploma or equivalent)
- Be fluent in English or French — reading, writing, and understanding technical documentation
- Have a clean aviation record with no enforcement actions by Transport Canada
Step 2: Choose Your License Category and Training Path
Decide between License M, E, or S based on your interests and career goals. Then choose your training pathway:
Path A: Approved College Program — Attend a Transport Canada-approved aviation maintenance program at institutions such as:
- British Columbia Institute of Technology (BCIT) — Burnaby, BC
- Canadore College — North Bay, ON
- Centennial College — Toronto, ON
- Northern Lights College — Dawson Creek, BC
- Holland College — Charlottetown, PE
- Université du Québec à Chicoutimi (UQAC) — Saguenay, QC
Programs typically last 18–24 months and can reduce your practical experience requirement from 48 months to 24–30 months.
Path B: Apprenticeship — Work under the direct supervision of a licensed AME for approximately 48 months while documenting your experience in an approved logbook. This route allows you to earn while you learn and gain real-world experience from day one.
Step 3: Complete Training and Begin Accumulating Experience
Enrol in your chosen program or begin your apprenticeship. Key experience areas you must develop competency in include:
- Inspection and testing of aircraft components and systems
- Repair and modification per approved data (manufacturer manuals, Service Bulletins)
- Troubleshooting and systematic fault diagnosis
- Record-keeping, journey log entries, and certification statements (CAR 571, CAR 626)
- Use of specialized tools, test equipment, and ground support equipment
- Safety practices, hazardous material handling, and environmental compliance
Step 4: Pass the Written Examinations
Study for and pass all five written exams. Each exam must be passed with a minimum score of 70%. Use Sky Licence's AI-powered practice platform to generate adaptive practice questions, simulate timed exams, and track your progress across every domain of the TP14038E syllabus.
Study tip: Focus on one exam at a time. Most candidates start with CARS and Standards (the regulatory knowledge base) before moving on to technical subjects. Allow 4–6 weeks of dedicated study per exam.
Step 5: Complete Your Practical Experience
Document your hands-on maintenance experience meticulously in a Transport Canada-approved logbook. Each entry should include the date, aircraft type, task description, reference to approved data, and the signature of your supervising AME. Organize your logbook by the competency areas specified by Transport Canada to streamline the review process.
Step 6: Pass the Oral and Practical Exam
The final regulatory hurdle is an oral and practical examination administered by a Transport Canada inspector. The inspector will test your depth of understanding across the TP14038E syllabus and evaluate your hands-on skills in a practical setting. Prepare by reviewing your logbook thoroughly, studying the syllabus in depth, and practising mock oral interviews with experienced AME colleagues.
Step 7: Submit Your Application
Once all exams are passed and practical experience is complete, submit your formal application to Transport Canada. Your package must include:
- Completed application form (available from Transport Canada Civil Aviation website)
- Official exam results for all written exams
- Certified logbook of practical experience
- Proof of training (college diploma or apprenticeship records)
- Valid Transport Canada Medical Certificate
- Application fee
Transport Canada will review your application and, once satisfied, issue your AME license. Congratulations — you are now authorized to sign maintenance releases and certify aircraft in Canada!

Frequently Asked Questions
Can I hold more than one AME license category?
Yes. Many engineers hold multiple categories (e.g., M + E or M + S). Each additional category requires passing the relevant written exams and demonstrating practical experience in that discipline. This makes you more versatile and valuable to employers.
How long are the written exam results valid?
Transport Canada considers written exam results valid for 5 years from the date of passing. If you do not complete your licensing process within that period, you may need to retake expired exams.
Is there a difference between AME and Aircraft Maintenance Technician (AMT)?
In Canada, the term AME (Aircraft Maintenance Engineer) is the official designation used by Transport Canada. In the United States, the equivalent is A&P (Airframe & Powerplant) mechanic. AMT is a generic term used internationally. The Canadian AME license is legally defined under the Aeronautics Act and CARS.
What happens if I fail an exam?
You can retake any failed exam. Transport Canada does not limit the number of retakes, but you must wait 30 days between attempts. Use the waiting period to focus on your weak areas. Sky Licence's adaptive question bank helps you target exactly the topics where you need improvement.
Do I need a college degree to become an AME?
No. While a Transport Canada-approved college program is the most efficient and structured route, you can qualify entirely through apprenticeship. However, the college route significantly reduces your practical experience requirement (by up to 24 months) and provides a more systematic theoretical foundation.
