Ontario Private Investigator Practice Exam 2026 - Free Private Investigator Practice Questions and Study Guide

A private investigator, while on the witness stand, may be permitted to refer to his or her notes with the court's permission. This is because notes can help refresh a witness's memory and ensure that they provide the most accurate and complete testimony. In this scenario, options A and D are incorrect because they suggest that a private investigator can freely use or not use their notes without permission, which is not the case. Additionally, option B is incorrect because witnesses, including private investigators, are not supposed to express their opinions on a case during testimony.
