Ontario Industrial Trades (OIT) Certification β Questions and Answers
Question 1: On a blueprint, the scale notation '1:2' means which of the following?
- 1 unit on the drawing equals 2 units in real life (Correct answer)
- The drawing has no defined scale
- 2 units on the drawing equal 1 unit in real life
- The drawing is full size
Correct answer: 1 unit on the drawing equals 2 units in real life
A scale of 1:2 means every 1 unit measured on the drawing represents 2 units in actual size, making the drawing half of real size.
Question 2: Which piece of Ontario legislation established Skilled Trades Ontario and restructured trade regulation in the province?
- Ontario College of Trades and Apprenticeship Act, 2009
- Building Opportunities in the Skilled Trades Act, 2021 (Correct answer)
- Trades Qualification and Apprenticeship Act
- Labour Relations Act, 1995
Correct answer: Building Opportunities in the Skilled Trades Act, 2021
The Building Opportunities in the Skilled Trades Act, 2021 dissolved OCOT and created Skilled Trades Ontario as the new regulatory body.
Question 3: On a blueprint dimension, what does a tolerance notation of '25.00 Β± 0.05' indicate?
- The tolerance applies only to the surface finish
- The feature may range from 24.95 to 25.05 units (Correct answer)
- The feature must be exactly 25.00 units
- The feature must be at least 25.00 units
Correct answer: The feature may range from 24.95 to 25.05 units
The Β± 0.05 tolerance means the actual dimension may be 0.05 units above or below the nominal 25.00, giving an acceptable range of 24.95 to 25.05.
Question 4: Which of the following is NOT a valid pathway to obtaining an Ontario Certificate of Qualification?
- Completing a registered apprenticeship and passing the certification exam
- Holding a journeyperson certificate from another province and applying for recognition
- Submitting a portfolio of photos of completed work as the sole requirement (Correct answer)
- Completing a Trade Equivalency Assessment and passing the certification exam
Correct answer: Submitting a portfolio of photos of completed work as the sole requirement
A portfolio alone does not satisfy Ontario's certification requirements; candidates must pass the provincial or interprovincial certification exam.
Question 5: On a piping or mechanical blueprint, what does the abbreviation 'NPS' stand for?
- National Plumbing Standard
- Normal Pipe Size
- Nominal Pipe Size (Correct answer)
- Non-Pressure System
Correct answer: Nominal Pipe Size

Question 21: What is the key difference between a 'specification' and a 'standard' in trade documentation?
- A specification defines requirements for a particular project; a standard is a general industry-wide requirement (Correct answer)
- Specifications are legally binding laws; standards are optional guidelines
- Standards are written by individual companies; specifications are written by government
- There is no difference β the two terms are interchangeable
Correct answer: A specification defines requirements for a particular project; a standard is a general industry-wide requirement
A specification is project-specific and defines the exact requirements for that job, while a standard is an industry-wide benchmark applicable across many projects.
Question 22: In technical drawing, what does GD&T stand for?
- General Drawing and Tolerance
- Grade, Dimension, and Template
- Global Design and Technology

- Complete the work as designed and note concerns in personal records only
- Contact the building owner directly and bypass the engineer
- Stop work on the affected portion and notify the engineer of record and supervisor (Correct answer)
- Proceed using personal judgment to fix it without documenting changes
Correct answer: Stop work on the affected portion and notify the engineer of record and supervisor
Identified design flaws must be escalated to the engineer of record and documented; tradespeople should not independently alter engineered designs.
Question 29: An apprentice is instructed by their journeyperson to take a shortcut that violates the Ontario Electrical Safety Code. The apprentice should:
- Complete the work and report it anonymously afterward
- Follow the instruction because the journeyperson holds authority
