The ministry has recommended various study materials to help operators prepare for their exams. They are not intended to replace the appropriate training and experience an operator should have.

The study guides and manuals provide a broad overview to the subjects covered on exams. They may not completely cover all exam subject areas.

Please note: Need-to-Know Guides do not apply to the Operator-in-Training examinations.


To order study materials

Study manuals can be ordered by submitting a completed Study Manual Order Form to the OWWCO office.

For information on which guides apply for your exam, please read Preparing for Your Exam.
