Introduction

In Ontario, there is a well-established practice of asking jurors to provide reasons for their verdicts. This practice is grounded section 108(5) of the Courts of Justice Act, R.S.O. 1990, c. 43, which gives trial judges, for jury cases, the discretion to require the jury to give a general verdict or answer specific questions, meaning jurors may be required to explain how or why they arrived at their general verdicts when answering specific questions.
