What the Course Entails and Exam Details

To be eligible for the G3 exam, individuals must first complete an accredited training program, which typically involves both theoretical classroom instruction and practical hands-on experience. The curriculum is based on the standardized TSSA Gas Technician 3 training, which spans approximately 12 weeks or 180 hours. The core units of study and the details covered include:

• Safety and Regulations: Covering the Occupational Health and Safety Act (OHSA), TSSA regulations, and personal protective equipment.

• Fasteners, Tools, and Testing Instruments: Identifying and using appropriate hand and power tools, and electrical testing devices.

• Properties and Safe Handling of Fuel Gases: Understanding the properties of natural gas and propane, and safe handling procedures.

• Utilization Codes, Acts, and Regulations: Deep knowledge of the governing provincial acts and the foundational standard, the CSA B149.1 Natural Gas and Propane Installation Code.

• Introduction to Electricity: Basic concepts, circuits, and troubleshooting, including reading technical schematics.

• Technical Manuals, Specifications, and Drawings: Interpreting engineering drawings and manufacturer instructions.

• Introduction to Piping and Tubing Systems: Concepts and methods for installing steel, copper, and plastic gas line systems.

• Introduction to Gas Appliances: Principles of combustion, appliance components, and venting basics.

What to Expect in the Final Exam

The final TSSA G3 licensing exam is a rigorous evaluation designed to test a student's technical knowledge and ability to navigate and apply industry codes. Unlike some practical components during the training course, the TSSA G3 final is a theoretical, written exam.

• Format: The exam consists of multiple-choice questions. It is an "open-book" exam, meaning candidates are permitted and expected to bring their annotated copy of the CSA B149.1 Natural Gas and Propane Installation Code Book.

• Passing Score: Candidates must achieve a score of at least 75% to pass and be eligible for their G3 license.

• Time Limits: While the precise time can vary slightly, candidates should expect the timed exam to last between three and four hours. Efficiently using the code book is critical to completing it on time.

• Rules: Effective September 1, 2024, all candidates must have a TSSA customer account, created through the TSSA Client Portal, to write the exam. The exam must be written within one year of completing the G3 training program.

How to Study and Exam Centers

Preparation is key to success on the G3 exam, especially regarding speed and accuracy with the code book.

Study Strategies:

• Take Practice Exams: Utilize "Gas Technician 3 (G3) License Practice Exam" resources extensively. These tests simulate the TSSA format, help identify weak areas, and, most importantly, train you to answer questions within the time limit. Treat each practice exam as a real test.

• Master the Code Book: Do not try to memorize every rule. Instead, master the index, table of contents, and specific tables of the CSA B149.1. Learn how to quickly find the required clauses and sections. Use tabs and highlights to make key areas faster to locate.

• Use Flashcards: Create flashcards for key definitions, electrical concepts, tool names, and essential formulas. This reinforces basic knowledge, freeing up mental energy for complex code-based questions.

• Review Class Materials: Thoroughly review the official modules from your accredited training, paying close attention to "Combustion principles," "Piping and Tubing Systems," and "Electricity."

Exam Centers:

The G3 licensing exam is not available via online portals or at common testing centers like Pearson VUE. It is administered by the TSSA and can only be taken at an accredited delivery agent (ADA). These are authorized colleges and private career colleges across Ontario that are licensed to deliver the G3 training program and conduct the final exam. You must register through your training school or directly with an accredited delivery agent after completing the necessary course requirements.
