The Elevating Device Mechanic exam is a closed-book, multiple-choice assessment designed to verify that candidates possess the necessary technical knowledge and regulatory awareness to work safely in Ontario. Depending on your apprenticeship and desired classification—such as a Class A (full mechanic) or Class F (construction hoist)—the exam scope will vary from 50 to 165 questions. You are expected to demonstrate proficiency in electrical troubleshooting, mechanical repair, and strict adherence to the Technical Standards and Safety Act.
The Technical Standards and Safety Authority (TSSA) governs the certification process in Ontario. However, the computer-based examinations themselves are proctored and administered in person by TSSA's third-party partner, Prometric. You must apply for eligibility through the TSSA Client Portal, but you will schedule the actual test date and location through the Prometric website once approved.
Achieving this certification is a legal requirement to work independently on elevating devices in Ontario. Without it, you are restricted to working as a mechanic-in-training under direct supervision. Certification proves your competence, drastically increases your earning potential, and opens doors to specialized roles in inspection, management, or highly technical troubleshooting within major elevator manufacturing companies.
The most challenging aspect for many candidates is interpreting the Code Adoption Document alongside the CSA B44 standard. Because regulations are heavily cross-referenced, candidates often struggle to find the definitive rule for a specific scenario. To conquer this, spend focused study sessions strictly on code navigation. Create an index of common regulatory topics and practice matching field scenarios to the exact legal clause. Use flashcards to memorize where specific dimensional tolerances and safety limits are located within the documents.
Calculating your final exam result is straightforward, as TSSA relies on a standard percentage-based system.
Determine the total number of questions on your specific exam (e.g., 150 questions for an EDM-A).
Count the total number of questions answered correctly. (All questions are typically scored equally).
Divide your correct answers by the total number of questions, then multiply by 100.
Example Result: If your exam has 150 questions and you answer 112 correctly, your score is (112 ÷ 150) x 100 = 74.6%. Since the passing mark is 70%, this would be a passing score.
Elevating Devices Mechanic (Class A): Install, maintain, and repair passenger and freight elevators. This role requires heavy lifting, precision electrical troubleshooting, and comfort working at heights in hoistways.
Elevator Inspector: Work directly for municipalities, private consulting firms, or regulatory bodies to ensure existing installations comply with the latest TSSA safety codes. This requires deep regulatory knowledge and a highly analytical mindset.
Escalator Specialist: Focus specifically on the complex mechanical chains, drives, and safety sensors of moving walkways and escalators in commercial spaces and transit hubs.
Accessibility Lift Technician: Specialize in installing and servicing lifts for persons with physical disabilities. This role often involves working in residential settings and requires strong customer service skills alongside technical expertise.
Confirm your scheduled time and location with Prometric at least 24 hours in advance.
Arrive at the testing center a minimum of 30 minutes before your appointment to complete the check-in process.
Bring a valid, unexpired government-issued photo ID (such as a driver's license or passport). Student IDs and health cards are not accepted.
Leave personal electronics, smartwatches, and cell phones in your car or the provided testing center lockers.
Bring approved, unannotated code books and reference materials if your specific exam classification permits open-book sections (check your TSSA eligibility letter for exact allowances).
Prepare to have your photo taken and your ID scanned as part of Prometric's strict security protocols.
Use the provided erasable whiteboard or scratch paper for complex electrical or mechanical calculations.
Manage your time carefully; keep an eye on the digital timer to ensure you have enough time to review flagged questions before the 3.5-hour limit expires.
Approaching your TSSA certification exam can feel overwhelming, but you have already put in the hard work during your hands-on training. This test is simply an opportunity to prove what you already know on paper. Break your study sessions into manageable daily goals, focus on understanding the "why" behind the safety codes, and trust in your preparation. Keep moving forward, and you will be ready.

Where do I actually take the test?
TSSA computer-based exams are proctored in person by Prometric. Once you receive your eligibility email from TSSA, you will use the provided instructions to book a seat at a local Prometric testing center.
How much does the exam cost?
The exam requires a flat pre-payment fee, typically around $156 CAD. This must be paid through the TSSA Client Portal via Visa or MasterCard at the time of your application.
What happens if I need to cancel my exam?
You can cancel or reschedule your exam directly through Prometric without penalty as long as you do so at least 22 days before your scheduled test date. Canceling closer to the exam date will result in forfeiting your fee.
Are there accommodations for candidates with disabilities?
Yes, TSSA is committed to providing equal opportunities. Candidates requiring accommodations must review the Examination Disability Accommodation Policy and submit their requests directly to TSSA for approval before booking with Prometric.
When will I find out if I passed?

Can I bring my own code books into the exam?
Certain exams allow specific reference materials (like the Code Adoption Document or CSA B44). You must verify the exact list of permitted, unannotated materials on your TSSA exam instruction sheet, as invigilators will strictly enforce these rules.
What do I do if my certification expires?
Every two years, EDM certificate holders must complete 12 hours of continuing education from an accredited provider, upload the proof, and pay a renewal invoice through the TSSA portal before the expiration date to maintain active status.
