Forklift (Lift Truck) Operator Theory Test (Ontario and Canada)

Ontario has no government forklift licence or exam. O. Reg. 851 requires lift trucks to be operated by a competent person, so your employer or training provider tests your theory knowledge and evaluates your driving on the truck. Our 40-question mock uses an 80% pass mark, which is a VoltExam assumption because no official question count or pass mark is published.

Only a competent person, or a worker being instructed who is accompanied by a competent person (O. Reg. 851, clause 51(2)(a)). source ↗
How competence is shown
The operator demonstrates the required skills to a person with expert knowledge of lift trucks. The employer should keep a record of the skills shown, the truck class, the assessor's name and affiliation, and the date. source ↗
Test format and pass mark
Not published. The training provider or employer sets the theory test and the practical evaluation. VoltExam's 40-question, 80% mock is our own assumption. source ↗
What training covers

Retraining
CSA B335 recommends operator retraining at least every three years (clause 6.21 of the 2015 edition). Confirm the current interval in the 2025 edition with your trainer. source ↗
Truck examination
A competent person must thoroughly examine each lift truck before first use, then as often as the manufacturer recommends and at least once a year, with a signed record (O. Reg. 851, clause 51(1)(b)). source ↗

How to get certified

  1. 1

    Find out which trucks you will drive

    Competence is tied to the truck class and the workplace. Ask your employer which class (for example a Class 1 electric counterbalanced truck or a Class 2 reach truck), attachments and site rules apply.

  2. 2

    Learn the theory

    Cover the knowledge topics in Appendix III(a) of the ministry guideline: the OHSA and O. Reg. 851, truck classes, the stability triangle, load centre, the capacity plate, the operator manual and the dangerous activities list.

  3. 3

    Practise under supervision

    Until you are competent, O. Reg. 851 lets you operate only while being instructed and accompanied by a competent person. Practise pre-use checks, driving, ramps, load handling and shutdown on the truck you will use.

  4. 4

    Pass the theory test and practical evaluation

    Your training provider or employer sets a written test and has you demonstrate the skills to a person with expert knowledge of lift trucks. There is no government exam to book.

  5. 5

    Get recorded as competent

    The guideline recommends a record of the skills shown, truck class, assessor and date. Many employers also issue a wallet card, which is proof of training, not a government licence.

  6. 6

    Keep your training current

    CSA B335 recommends retraining at least every three years. Expect extra training when you change truck class, add an attachment, move to a new site or after an incident.

How to study

  • Learn the stability triangle and load centre until you can explain why a raised, forward-tilted or long load tips a truck. Many theory questions are scenarios built on these ideas.
  • Memorize the ramp rule: with a load, keep the load uphill (forward up, reverse down); without a load, keep the forks downhill (forward down, reverse up). Never turn on a ramp.
  • Read the capacity plate on a real truck and practise comparing a load's weight and load centre with the rating.
  • Know the key O. Reg. 851 sections: s. 51 (competent operation, yearly examination, no load over workers), s. 52 (lifting workers), s. 56 (signallers), ss. 57-58 (unattended equipment) and s. 59 (no overloading).
  • Walk through the CCOHS daily check list on a truck: engine-off visual checks first, then operational checks with the truck running.
  • Practise timed sets: a 40-question mock at 80% means no more than eight wrong answers.

Frequently asked questions

Do I need a government forklift licence in Ontario?

No. Ontario does not issue forklift licences. O. Reg. 851 requires lift trucks to be operated by a competent person, and the ministry guideline says it is the employer's responsibility to establish that competence, usually through training, a theory test and a practical evaluation.

How long is forklift certification valid?

No Ontario law sets an expiry date. CSA B335 recommends retraining operators at least every three years, and many employers follow that. You may need retraining sooner after an incident or when you change trucks or workplaces.

Does my forklift card transfer to a new job?

Your card shows past training, but each employer must make sure you are competent on its trucks, attachments and site. Expect at least a practical evaluation and site orientation at a new workplace.

What is on a forklift theory test?

Providers set their own tests, usually based on the ministry guideline's knowledge topics: the law, truck classes, stability and load centre, the capacity plate, pre-use inspection, safe travel, load handling, pedestrians, refuelling or charging, and parking. No official question count or pass mark is published.

Can I get forklift certified completely online?

You can study theory online, and CSA B335:25 adds online and virtual reality simulation as instruction and evaluation methods. Ontario's guideline still expects operators to demonstrate the skills to a knowledgeable assessor, so plan on a hands-on evaluation on the truck you will drive.

Can a forklift be used to lift a person?

Only under strict conditions. In an industrial establishment, O. Reg. 851 s. 52 requires a proper platform, a load under half the rated load if the truck is not designed for people, a sign showing the allowed load and controls attended by another worker. The guideline says lift trucks may not lift workers on construction projects.

Which rules apply at a federally regulated workplace?

Ports, airports, interprovincial trucking and other federal workplaces fall under the Canada Labour Code and the Canada Occupational Health and Safety Regulations. Part XIV requires operator training in inspection, fuelling and safe use, with records kept while the operator is employed.
