Two exam lines, one study method
Every guide follows the same format: the exam facts, module-by-module theory with worked examples, a cram sheet of must-memorize numbers, and a full practice exam with explained answers.
TSSA Gas Technician G3 & G2

HCRA competency guides
One guide for each of the seven competencies required for an Ontario home builder or vendor licence. Built for experienced contractors preparing to write HCRA challenge exams.

Exam prep written for Ontario's tests
Generic study material doesn't cut it for Ontario licensing exams. The TSSA Gas Technician G3 exam is an open-book, code-navigation test drawn from all nine G3 curriculum units, and the G2 exam builds on it with fifteen more advanced units on piping, venting, controls, and heating systems. Our G3 & G2 guide teaches all 24 units the way the exams test them, with code-check drills that train you to find answers in your own CSA B149.1 and B149.2 books under time pressure.
The HCRA challenge exams are a different kind of test: seven separate competency exams for Ontario home builder and vendor licensing, each with a 70% pass mark, written for experienced contractors who can challenge without taking the course. Each of our seven HCRA study guides covers one competency in depth — business planning, financial management, project management and supervision, legal issues in housing, customer service and Tarion requirements, the Ontario Building Code, and construction technology — so you buy only the exams you still need after your CCEP decision.
Every guide is a practice-exam-first study system: learn the material, drill the numbers and code references, then sit a full timed practice exam with explained answers before your real exam date. See the G3 & G2 guide or browse the HCRA guides.

Questions
Are these official exam materials?
No. These are independent study aids. They aren't produced, reviewed, or endorsed by the HCRA, Tarion, the TSSA, CSA Group, or any course provider or training college, and they don't guarantee a passing grade.
How do I get my guide after buying?
Checkout is handled by our payment provider, and we never see your card number. Your download link appears right after payment and is also sent to your email.
I didn't get my download email.
Check your spam folder first. If it isn't there, email info@ontariobuilderexams.ca with the address you used at checkout and we'll resend it.
Can I get a refund?

Are the guides up to date?
Each guide shows the date it was last revised. Requirements and codes change, so always confirm current details with the issuing authority — the HCRA for builder licensing, the TSSA for gas technician certification — before writing an exam.
